Authors: Wadhwa Sanjay , Das Pallab , Singh Naorem Ajit , Suresh R , Araf Mahiuddin , Singh U.
Published: July 2019

The benign joint hypermobility syndrome (BJHS) was first addressed by Kirk as a distinct pathology in 1967, as the presence of rheumatic symptoms with generalised joint laxity in the absence of any demonstrable systemic rheumatic disease.

In this prospective, longitudinal, analytical study, we tried to find out the response of rehabilitation therapy in patients presenting with locomotor symptoms of BJHS and selected 61 patients randomly. The rehabilitation protocol followed: Explanation and reassurance, teaching of joint protection techniques and work modification, isometric muscle strengthening exercise (both extensor and flexor muscles), endurance exercise. Clinically most of the patients showed significant overall response quantitatively, in all the parameters.

It can be concluded that the rehabilitation protocol prescribed here is very much suitable both quantitatively and qualitatively for the patients of BJHS.

Authors: Kumar Shwetha
Published: July 2019

Ameloblastoma is an epithelial odontogenictumour of the jaw and exhibits diverse histopathologic subtypes like follicular, plexiform, acanthomatous and desmoplastic variantswhich occurs either singly or in combination. Granular cell ameloblastoma is a rare histological subtype of ameloblastoma accounting for less than 5% of the total. The rare granular cell variant is seen in combination usually with follicular or plexiform subtypes. The aim of this paper is to describe clinical and microscopic features of Ameloblastoma of a pure granular cell histopathological subtype occurring in a seventeen year old adolescent female patient in the lower right region of the mandible.
Neutrophil Exodus From The Gingival Crevice - A Novel Method of Quantification Using Durapore Filter Strips: A Cross Sectional Study
Authors: Kulkarni Sudhindra , Kanagotagi Sachin
Published: July 2019

Objectives

Neutrophils play a critical role as a part of the innate immune response. Although neutrophils are primarily protective, they release products partly responsible for the destruction seen in periodontal disease. The techniques presently available for counting neutrophils require special equipment and are only semi-quantitative. The aim of the present investigation was to check the efficacy of a single, rapid, non-invasive assay to enable the expedient quantification of oral neutrophils, and utilize the assay to quantify the number of neutrophils in periodontal disease.

Materials and Methods

Forty five subjects were recruited in the study. They were put into three groups based on the Gingival Index and Russell's Periodontal Index as clinically healthy (Group 1), gingivitis (Group 2) and periodontitis (Group 3). GCF samples were collected using a durapore filter and the number of neutrophils counted using an improved Neubaeur's Chamber.

Results

Neutrophils were present in GCF of all the samples. There was statistically significant difference between the neutrophil numbers in all the samples with respect to severity of periodontal disease. The strength of association was the strongest between probing pocket depth and neutrophil counts.

Conclusion

This study demonstrates that it is possible to collect and quantify oral neutrophils by a single, rapid, noninvasive assay using durapore strips.

Published: July 2019

Pulp therapy helps in preserving a pulpally involved primary tooth by eliminating bacteria and their products and ensures hermetic seal of the root canals so that the primary tooth can complete its function without harming the successor or affecting the health of the patient. A thorough understanding of the pulp morphology and root formation and resorption in primary teeth as well as different materials and techniques used is imperative for a successful pulp therapy. One of the major areas of continued research is in the area of finding obturating materials to suit the specific properties of these teeth. This article seeks to present a review of the major obturating materials and techniques with their modifications as well as their advantages and disadvantages.

Assessment of the Effect of Selected Snack Foods on the Remineralization/Demineralization of Enamel and Dentin
Authors: Jensen Mark E. , Donly Kevin , Wefel James S.
Published: July 2019

This study utilized volunteer subjects to examine caries-like lesions for remineralization and demineralization patterns in dentin and enamel when nine different snack foods were eaten between meals. Caries progression was observed in enamel and dentin when apple juice, a cola beverage, and sweetened (strawberry) yogurt were consumed as snacks. Remineralization of enamel was observed when cheddar cheese, skim milk, 2% milk, whole milk, chocolate milk, and orange juice were used as between meal snacks. Dairy products, with the exception of the sweetened yogurt, generally reduced the amount of demineralization produced in dentin. This study helps establish a scientific basis for appropriate between-meal snacks for patients who are concerned about their dietary habits as a part of their overall preventive oral health plan.
Coaching for a Winning Dental Team
Authors: Schvvartz Steven
Published: July 2019

In 1943, Abraham Maslow, the “father of humanistic psychology,” formulated his “Hierarchy of Needs Theory.” Maslow proposed people have needs that must be satisfied, and these needs will motivate until they are satisfied. The needs are arranged in a hierarchy or pyramid ranging from basic needs to higher needs with an individual needing to satisfy a lower need before a higher need can motivate. The five needs of the hierarchy are: physiological needs, safety needs, social needs, esteem needs, and self-actualization. This article discusses adaptation of the hierarchy of needs to the dental practice to motivate staff to perform at a higher level.
Effectiveness of Dentist-Prescribed, Home-Applied Tooth Whitening, A Meta-analysis
Authors: Niederman Richard , Tantraphol Maggie C. , Slnin Patricia , Hayes Catherine , Conway Suzy
Published: July 2019

Introduction

Common clinical experience suggests that tooth whitening agents are 100% effective. This study uses meta-analysis of data from published randomized controlled clinical trials to determine the efficacy of tooth whitening agents.

Methods

A MEDLINE search strategy was developed and implemented to systematically identify clinical trials on dentist-prescribed, home-applied tooth whitening agents, using 10% carbamide peroxide, published between 1989-1999. Inclusion criteria (e.g., in English, human clinical trials) and exclusion criteria (e.g., not placebo controlled) were established and clinical trials that met these criteria were critically appraised for validity and clinical applicability. Meta-analysis was then used to quantitatively integrate the findings.

Results

Seven studies were identified that met the inclusion and validity criteria. These studies indicated that:

Whitening results in a significant mean change of 6 4 shade guide units (p < 0.01), while the placebo control group exhibited little change (0.7 0.6, p > 0.05).

93% of the bleached patients exhibited 2 shade guide unit change, while 20% of the placebo control group exhibited this change.

The brand of bleaching agent had a significant effect on tooth whitening, but the daily application time and duration of treatment did not.

Whitening is maintained for 6 months for 1/2 of the people treated.

Neither gingival indices nor plaque indices were adversely or favorably affected by bleaching.

Clinical Applicability

The data from the reviewed studies indicate that rather than being 100% effective, on average:

73% (93% for bleached group minus 20% placebo group) of people who whiten their teeth will exhibit a whitening that is 2 shade guide units greater than the placebo.

20% of the people who use dentist-prescribed, home-applied bleaching will achieve a mean whitening effect of 5 shade guide units.

Re-treatment for 50% of people may be necessary to maintain this effect longer than 6 months.

The methods used here are Internet applicable for other clinical topics.
Thermal Variations in the Pulp Chamber Associated with Composite Insertion Techniques and Light-curing Methods
Authors: Sinhoreti Mário Alexandre Coelho , Guiraldo Ricardo Danil , Consani Simonides , Correr-Sobrinho Lourenço , Schneider Luis Felipe Jochims
Published: July 2019

Aim

The aim of this study was to investigate the effect of different incremental insertion techniques, photoactivation, and restorative phases on thermal variations occurring during the polymerization of Filtek Z250 composite resin.

Methods and Materials

The experiment was conducted using 90 bovine incisor teeth. The teeth were randomly assigned to three groups according to the technique used for photoactivation with a halogen light (continuous, soft-start, or intermittent). The groups were further separated into three subgroups according to method of increment placement (bulk, oblique, or horizontal/vertical) for a total of nine groups (n=10). Restorations were placed in a controlled environment (37°C and 50±10% RU) and the temperature recorded using a digital thermometer coupled to a Type-K thermocouple inserted in the pulp chamber through the root canal in contact with the dentin. Data were analyzed using an analysis of variance (ANOVA) and the Tukey's test.

Results

Higher temperature values were found for continuous light photoactivation in combination with the placement of horizontal/vertical composite increments and photoactivation of the adhesive using a continuous light exposure.

Conclusion

The light source is the most important factor producing temperature changes during photoactivation of resin composite.

Clinical Significance

Temperature increases in the pulp chamber due to light curing should be considered to avoid harming the delicate pulp tissue when large restorations or inlays/onlays require several consecutive light curing exposures for a complete cure.

Oral and Maxillofacial Manifestations of Familial Adenomatous Polyposis (Gardner's syndrome): A Report of Two Cases
Authors: Martins Wilson Denis , de Oliveira Ribas Marina , Martins Guilherme , de Sousa Maria Helena , de Aguiar Koubik Ana Claudia Galvão , Åvila Lucia Fåtima Castro , Zanferrari Fernando Luis
Published: July 2019

Aim

The aim of this case report is to emphasize the importance of an early diagnosis of Gardner's syndrome through the detection of lesions appearing in the oral and maxillofacial area as well as to present two cases of the disease.

Background

Gardner's syndrome is an autosomal dominant disease characterized by gastrointestinal polyps that develop in the colon as well as in the stomach and upper intestine, along with multiple osteomas, skin, and soft tissue tumors. Cutaneous findings may include desmoid tumors, epidermoid cysts, and other benign tumors. Early diagnosis and therapy of the disease are critical because polyps have a 100% risk of undergoing malignant transformation. Craniomaxillofacial manifestations (osteoma formation, tooth impaction, diffuse opacities in the skull, mandible and maxilla, scalp tumors) usually precede polyposis.

Report

Case 1: Gardner's syndrome was diagnosed in a 25-year-old Caucasian man who was referred by his endodontist for evaluation of an uncommon radiographic image in the mandibular molar area. Further investigation revealed a familial adenomatous polyposis (FAP) complicated by adenocarcinoma of the colon. A colectomy and an ileorectal anastomosis were performed. Case 2: A 12-year-old Caucasian girl, who is a niece of the patient described in Case 1, presented with progressive difficulty with mouth opening but no complaints of digestive problems. Radiographic examination revealed multiple radiopacities in the maxilla, mandible left temporomandibular joint, and in the left mandibular angle. Multiple impacted teeth were present. A colonoscopy was suggested, but the patient's parents decided to continue the investigation and treatment with their own physician in their home town.

Since an early diagnosis is essential and general dental practitioners may be the first healthcare professionals to suspect the diagnosis, it is important for them to be familiar with the features of Gardner's syndrome.

Correlation between Levels of Sulcular and Capillary Blood Glucose
Authors: Moeintaghavi Amir , Ardakani Mohammad Reza Talebi , Haerian Ahmad , Ardakani Mohammad Afkhami , Hashemzadeh Mahdi
Published: July 2019

Aim

The aim of this study was to evaluate the correlation between capillary blood glucose levels (CBGLs) and sulcular blood glucose levels (SBGLs) using blood obtained from gingival tissue during routine periodontal examinations to determine if sulcular blood samples can be used as a non-invasive means to diagnosis blood glucose levels.

Methods and Materials

Thirty non-diabetics and 30 diabetic patients with moderate to severe periodontitis were included in the study and subjected to routine clinical periodontal examinations. Blood was collected using a 1.6-1.8 mm diameter micro bite collection tube to transport the sample from the gingival sulci of anterior teeth following periodontal pocket probing to a test strip of a glucose self-monitoring device. As a control, capillary blood was taken with a finger-stick. Statistical analysis was performed using the Pearson's correlation coefficient and a t-test.

Results

The blood glucose levels in patients ranged from 58 mg/dl to 477 mg/dl, and the values of blood samples taken from gingival sulcus or finger tip of the same patient showed a very high intra-patient correlation (r =0.99, p< 0.0001).

Conclusion

The results of this study suggest sulcular blood from a routine periodontal examination may be used for diabetes mellitus screening.

Clinical Significance

Considering 50% of diabetics remain undiagnosed, testing sulcular blood may provide a suitable method for identifying potential diabetic patients during routine dental visits since there is a correlation with capillary blood. Appropriate referrals to a physician can then be made when warranted.

Microleakage of an Adhesive System used as a Fissure Sealant
Authors: Imparato José Carlos Pettorossi , Raggio Daniela Prócida , Bonifacio Clarissa Calil , Navarro Ricardo Scarparo , Sardenberg Fernanda , de Carvalho Rubens Corte Real
Published: July 2019

Aim

The aim of this study was to investigate the microleakage of pit and fissure sealants in primary teeth and to determine if multi-step methods should produce better results in terms of microleakage prevention.

Methods and Materials

A total of 40 intact primary molars were randomly assigned to one of four sealant groups: resin based sealant Ultraseal XT (US – Ultradent) (Group 1, n=10); adhesive system Scotchbond Multi Purpose Plus (SBMP - 3M/ESPE) used as a sealant (Group 2, n=10); primer (SBMP) and US (Group 3, n=10); and primer, bond (SBMP) and US (Group 4, n=10). After thermocycling (x700, 5-55°C) all teeth surfaces were made impermeable with the exception of the occlusal surface. Samples were immersed in 50% silver nitrate for 8 hours, sectioned longitudinally with two cuts in the central fissure pit, and then immersed in photo development solution followed by 16 hours in fluorescent light. Pictures were obtained by light microscope (x40) and the degree of microleakage was evaluated by three blinded evaluators. The data were analyzed using the Kruskal Wallis test.

Results

Significant statistical differences (p<.05) were observed between Groups 1-3, Groups 2-3, Groups 2-4, and Groups 3-4. Group 3 showed higher microleakage scores.

Conclusion

The adhesive system and the resin based sealant demonstrated similar microleakage properties, suggesting the possibility that adhesives can be used in a clinical setting. Additionally, the increase in the number of clinical steps required by common application of resin based sealant, including use of primer or primer and bond, did not lead to better results in preventing microleakage.

Clinical Significance

The adhesive system can be used as a sealant without increasing the microleakage. Thus, the use of the adhesive system before the application of the sealant is not necessary to reduce the microleakage, although further research is warranted to support this conclusion.

Effect of Multiple Consecutive Applications of One-step Self-etch Adhesive on Microtensile Bond Strength
Authors: Arisu Hacer Deniz , Ömürlü Hüma , Eligüzeloğlu Evrim , Üçtaşli Mine
Published: July 2019

Aim

The aim of this study was to evaluate the effects of multiple consecutive coatings of a one-step self-etch adhesive system (Clearfil Tri-S Bond) on the microtensile bond strength (MBS) to dentin.

Methods and Materials

Nine caries-free human lower third molars were sectioned perpendicular to the long axis to expose the mid-coronal dentin. The teeth were separated into three experimental groups (n=3) according to the number of adhesive resin coats applied. In Group 1 one layer of Clearfil Tri-S Bond was applied according to the manufacturer's instructions. In Group 2 and Group 3 the adhesive was applied in two and three layers, respectively. In these two groups the first layer was applied according to the manufacturer's instructions but the second and third layers of adhesive were not light cured after application. After the placement of the composite, the teeth were sectioned to obtain approximately 1 mm2 beams for testing. Eighteen beams were prepared for each group using the ‘non-trimming’ method. The MBS values of all specimens were tested, and fracture modes were then determined using a stereomicroscope.

Results

The mean MBS values (in MPa) of Group 1 (one coat of the adhesive) was significantly lower (p=0.04) than those of Group 3 (three applied coats of the adhesive). There were no statistically significant differences between Groups 1 and 2 and Groups 2 and 3.

Conclusion

Within the limitations of this in vitro study the application of multiple coats of a one-step self-etch adhesive may provide an increase in bond strength compared to the application of only one coat of adhesive.

Clinical Significance

Three consecutive coats of one-step self-etching adhesive application can improve MBS.

Angulation of Mandibular Third Molars as a Predictive Factor for Pericoronitis
Authors: Bataineh Anwar , Hazza'a Abdalla , Odat Abd-albaset
Published: July 2019

Aim

The aims of this study were to investigate the association between pericoronitis and the angular position, state of eruption, and the depth of impaction of mandibular third molars as well as to compare these findings with similar studies.

Methods and Materials

A total of 242 patients ranging in age from 18 to 41 years of age suffering from pericoronitis were examined. Subjective and objective observations were recorded on a checklist that included the name, age, gender, type of pericoronitis and state of eruption, position of the affected tooth for each patient as well as any radiographic changes in the mandibular third molars.

Results

The peak age for the occurrence of pericoronitis was in the 21-25 year-old age group. The soft tissues adjacent to vertically inclined, partially erupted mandibular third molars at the level of or above the occlusal plane were the most commonly affected. There was a statistically significant association between radiographic changes and the mesioangular position of the tooth (p<0.002) and the age group of the subject (p=0.004), but the association was not statistically significant between the gender of the subject, type of pericoronitis, state of eruption, and depth of impaction.

Conclusion

The soft tissues adjacent to vertically inclined, partially erupted mandibular third molars were more frequently affected by pericoronitis than teeth that are soft tissue impacted or erupted. Mesioangular erupted third molars were the teeth most frequently associated with bone loss.

Clinical Significance

The soft tissues at highest risk of developing pericoronitis are those adjacent to mandibular third molars that are partially erupted, in a vertical position, and erupted to the level of or above the occlusal plane.

Teething Problems and Parental Beliefs in Nigeria
Authors: Owotade Foluso J. , Folayan Morenike O. , Esan Temitope A. , Oziegbe Elizabeth O. , Adekoya-Sofowora Comfort A.
Published: July 2019

Aim

To determine signs and symptoms associated with teething, parental beliefs about teething, and the effects of socioeconomic status on teething in Nigerian children.

Methods and Materials

A cross-sectional study consisting of 1,013 mothers of children between the ages four to 36 months who visited the immunization clinics at the Community Health Centres in Ife Central and Ife East Local Government Areas. Data was analyzed using STATA (Intercooled release 9) for Windows.

Results

A total of 765 mothers (75.5%) reported systemic signs and symptoms in their children. Fever (51.8%), diarrhea (12.5%), and vomiting (2.9%) were the most prevalent symptoms and signs reported. Teething problems were reported by 60% of mothers from a high socioeconomic class, as well as 76.7% and 77.9% from middle and low socioeconomic classes, respectively. Interestingly, 65.5% of mothers believed teething should be accompanied with systemic signs and symptoms such as fever (42.1%), diarrhea (13.9%), and vomiting (0.6%). No significant difference was noted between breastfeeding status, gender of the child, and reported systemic signs and symptoms noticed by the mothers.

Conclusion

Most mothers in the study reported signs and symptoms adduced to teething in their children irrespective of their beliefs. Fever ranked highest of the signs and symptoms reported. Mothers of children from the high socioeconomic class reported fewer teething symptoms. Breastfeeding status and gender of the child had no effect on teething problems in the children studied.

Clinical Significance

Most signs and symptoms adduced to teething by parents may actually be due to underlying infections. Thus, there is a need to rule out occult infection during the tooth eruption period.

Aggressive Pregnancy Tumor Mimicking A Malignant Neoplasm: A Case Report
Authors: Ababneh Khansa , Al-Khateeb Taiseer
Published: July 2019

Aim

The aim of this report is to present the management of an aggressive, highly proliferative pregnancy tumor with clinical and radiographic characteristics highly suggestive of a malignant neoplasm.

Background

Pregnancy tumor is a benign hyperplastic gingival lesion occurring during pregnancy that is indistinguishable from a pyogenic granuloma arising in nonpregnant females, or in males. The lesion usually grows over a few months and tends to bleed.

Case Description

A 28-year-old woman at four months of gestation was referred for a massive gingival swelling (5.5 cm in greatest diameter) on the mandibular left side. The lesion was painful and continued to grow very rapidly over a threeweek period, with spontaneous bleeding, and it interfered with speech and mastication. Advanced alveolar bone loss also was found beneath the lesion. A malignant process was suspected, and an incisional biopsy revealed a pregnancy tumor. The lesion was excised under general anesthesia during the pregnancy with no untoward reactions.

Pregnancy tumor represents an important differential diagnosis of oral masses and can behave in a very aggressive fashion, mimicking a malignant tumor.

Clinical Significance

This lesion should always be included in the differential diagnosis of soft tissue masses in a pregnant woman even if the lesion is clinically very aggressive. It is acceptable practice to excise aggressive variants of this lesion during pregnancy to avoid distressing side effects.

Periodontal Bacterial Load: A Proposed New Epidemiological Method for Periodontal Disease Assessment
Authors: Feres Magda , de Figueiredo Luciene Cristina , Vettore Mario Vianna , Leão Anna Thereza Thomé , Leal Maria do Carmo , Sheiham Aubrey
Published: July 2019

Aim

The purpose of this study was to identify a periodontal clinical measure that correlates with red complex bacteria usually associated with periodontal disease.

Methods and Materials

Periodontal clinical parameters were recorded in 116 postpartum women at six sites per tooth for all teeth excluding third molars. Two subgingival plaque samples per subject were collected and analyzed for 39 bacterial species using the Checkerboard DNADNA hybridization technique. Periodontal Bacterial Load (PBL) was calculated as the sum of all pocket depth measurements of 4 mm at sites with a Clinical Attachment Level (CAL) of 4 mm. The association of clinical and bacterial scores was analyzed using the Spearman correlation coefficient and the Kruskal-Wallis test.

Results

The PBL was correlated with microorganisms from the red complex that included Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola, individually or grouped (p<0.05). The PBL was not associated with periodontally beneficial species from the yellow, green, purple, and blue complexes (p>0.05). The proportions and mean counts of the red complex were increased according to the quartile groups of distribution of the PBL.

Conclusions

PBL appears to be a reliable measure of periodontal status in postpartum women.

Clinical Significance

PBL avoids bias in the assessment of periodontal status in studies of periodontal disease.

Evaluation of a New Intraoral Paralleling Device for Creating Guiding Planes: A Pilot Study
Authors: Borges Alessandra Buhler , Borges Alexandre Luiz Souto , Uemura Eduardo Shigueyuki , de Arruda Paes-Júnior Tarcisio José , Tango Rubens Nisie , de Araújo José Eduardo Junho , Kimpara Estevão Tomomitsu
Published: July 2019

Aim

The aim of the study was to assess the accuracy of a new intraoral paralleling device for creating proximal guiding planes for removable partial dental prostheses.

Methods and Materials

Thirty gypsum casts were divided into two groups in which the proximal surfaces of selected teeth were prepared using either a surveying device (Group 1) or the new ParalAB paralleling device (Group 2). In each cast guiding planes were prepared on the distal surface of the maxillary left canine (A), on the mesial and distal surfaces of the maxillary left second molar (B and C), and on the distal surface of the maxillary right canine (D). Each prepared surface formed an angle related to the occlusal plane that was measured five times and averaged by one operator using a tridimensional coordinate machine.

Results

The mean guiding plane angles (± standard deviation) for the prepared surfaces were A=91.82° (±0.48°), B=90.47° (±0.47°), C=90.21° (±0.76°), and D=90.50° (±0.73°) for the dental surveyor (Group 1) and A=92.18° (±0.87°), B=90.90° (±0.85°), C=90.07° (±0.92°), and D=90.66° (±0.76°) for the ParalAB paralleling device (Group 2). A two-way ANOVA, Tukey's, and Levène's tests (at p<0.05) revealed statistically significant differences among surfaces prepared by both groups and that one surface(A in Group 2) was more parallel to the path of insertion than the other surfaces.

Conclusions

The ParalAB device was able to prepare parallel surfaces and despite significant difference between groups, the ParalAB presented a small deviation from absolute parallelism and can be considered a valid method to transfer guide plans in the fabrication of removable partial dentures.

Clinical Significance

The preparation of suitable guiding planes on abutment teeth during the fabrication of removable partial dentures is dependent on the ability of the operator and requires considerable chair time. When multiple teeth are involved, achieving parallelism between abutment surfaces can be technically challenging, especially in posterior regions of the mouth. The ParalAB prototype intraoral paralleling device can aid the clinician during the preparation of accurate guiding planes with a minimum degree of occlusal divergence.

A New Concept in Restorative Dentistry: LIFEDT— Light-Induced Fluorescence Evaluator for Diagnosis and Treatment: Part 2 – Treatment of Dentinal Caries
Authors: Tassery Hervé , Koubi Stephen , Raskin Anne , Terrer Elodie , Dionne Alexandro , Weisrock Gauthier , Sarraquigne Caroline , Mazuir Alain
Published: July 2019

Aim

A new and innovative therapeutic concept using a light-induced fluorescence evaluator for diagnosis and treatment (LIFEDT) of dental caries based on the imaging and autofluorescence of dental tissues is proposed. The aims of this series of in vivo experiments are to compare and analyze the brightness variations of sound dentin and active and arrested carious dentin illuminated with an intraoral LED camera and to determine if this new device could be helpful in daily practice to discriminate between caries and sound dentin.

Methods and Materials

A new intraoral LED camera that emits visible blue light was used in this in vivo study to illuminate and photograph 15 teeth at high magnification. The magnified images were examined using the free Image J V® version 1.41 software. Four standardized rectangular areas were drawn on each picture that included both healthy and pathologic areas to analyze variations in brightness using a brightness formula: L* = 0.299 Red + 0.587 Green + 0.114 Blue.

Results

Statistically significant differences in the brightness were found between active and arrested caries processes in an area of infected dentin designated Z2. Within the limitations of this in vivo study, the images created with the intraoral LED camera revealed significant variations in fluorescence between sound dentin and active and arrested caries processes.

Conclusions

The LIFEDT concept provides a therapeutic concept based on these findings of variations in fluorescence between healthy and pathologic tissue.

Clinical Significance

This concept defines a pragmatic clinical and therapeutic approach for treating active and arrested carious lesions based on the interpretation of variations of a fluorescence signal and applying the LIFEDT concept to the treatment of dentin carious lesions.

Comparative Evaluation of Ketoconazole Tablet and Topical Ketoconazole 2% in Orabase in Treatment of Candida-Infected Denture Stomatitis
Authors: Khozeimeh Faezeh , Savabi Omid , Shahtalebi Mohammad Ali , Noori Mojtaba
Published: July 2019

Aim

Denture stomatitis is a common and recurring problem of denture wearers. Ketoconazole tablet is one of the antimycotic drugs that often has been used to treat this condition, but systemic use of this drug has some adverse effects that frequently lead to unfavorable compliance and treatment failure. This study was designed to compare the efficacy of topical ketoconazole 2% in orabase and ketoconazole tablet.

Methods and Materials

Thirty patients with denture stomatitis (positive culture) were divided into two groups. The first group received ketoconazole tablet (orally used 200 mg per day) for 14 days and the second group received 2% topical ketoconazole in orabase applied twice daily on the mucosal denture surface. Candida cultures were taken from the palatal mucosa before and on days 7 and 14 after commencement of the therapy. The mean of colonies before and 7 and 14 days after medication were calculated. Oneway ANOVA and paired t-test were used for data analysis (α=0.05).

Results

The mean of colonies number before receiving medication in the tablet and topical application groups were 454 and 441 respectively. The mean of colonies number after receiving medication in tablet and topical application group were 137 and 176 (on the seventh day) and 122 and 96 (on the 14th day), respectively; there was no significant difference between the two groups after medication (p=0.18).

Conclusion

Topical ketoconazole 2% in orabase can be useful in managing denture stomatitis. This topical medication has fewer side effects, whereas systemic administration of ketoconazole tablet is associated with some complications.

Clinical Significance

The application of topical ketoconazole 2% in orabase ointment can be considered in the treatment of denture stomatitis and has comparable efficacy with the ketoconazole tablet.

Public Awareness Level of Oral Cancer in a Group of Dental Patients
Authors: Peker Ilkay , Alkurt Meryem Toraman
Published: July 2019

Aim

The aim of this study was to evaluate levels of public awareness and knowledge about early signs and risk factors of oral cancer among a group of dental patients in Turkey.

Methods and Materials

This study included 1022 participants. Sociodemographic information of patients was obtained. A questionnaire about awareness and knowledge of oral cancer and early signs and risk factors related to the disease was completed by two examiners. Data were statistically analyzed with descriptive analyses, crosstabs and chi-square tests.

Results

In total 60.7% of participants had never heard of oral cancer. While 79.2% of the participants were unaware of the early signs related to oral cancer, 29.9% of them were unaware of risk factors of the disease. There were no statistically significant differences between age, gender, and education levels for awareness of risk factors. Statistically significant differences were found between age and gender and no statistically significant difference was found between education levels for awareness of early signs.

Conclusion

This study showed that public awareness and knowledge about oral cancer were insufficient in Turkey.

Clinical Significance

There is an important need to inform the public about oral cancer, its risk factors, and early signs of the disease. Media campaigns can be useful to raise oral cancer awareness.

Microleakage Evaluation of Core Buildup Composite Resins with Total-Etch and Self-Etch Adhesive Systems
Authors: Moosavi Horieh , Moazzami Saied Mostafa , Loh Shaghayegh , Salari Soheil
Published: July 2019

Aim

Core buildup composite resins with prefabricated posts are commonly used to restore endodontically treated teeth. This study compared the sealing ability of Core Max II and Panavia F2.0 cement with total-etch and self-etch adhesive systems.

Methods and Materials

Sixty recently extracted human second premolar teeth were chosen and their crowns were cut 3 mm above the CEJ. After preparing proximal boxes (4±1 mm buccolingually and 3 mm occlusogingivally dimensions) and finishing root canal therapy, the teeth were randomly divided into four groups (n=15): groups 1 and 2, Core Max II without and with total-etch adhesive; groups 3 and 4, Clearfil photocore composite, A2 shade, and Panavia F2.0 cement without and with self-etch adhesive respectively. The Dentatus posts (# 2 Long) were used in canals approximately 8 mm depth. According to manufacturer guidelines, pins were cemented and cores were restored. After keeping the specimens for 24 hours at 37°C and 100% humidity, they were thermally cycled for 500 cycles, sealed with nail varnish except 1 mm beyond the margins of restoration, and then immersed in a 0.5% fuschin basic for 24 hours. Samples were embedded in clear epoxy resin, sectioned mesiodistally, and observed at 20× magnification. The microleakage was assessed under stereomicroscope and the results were recorded in percentage of dye penetration to the whole path from the cavosurface margin of the proximal boxes to the end of the post. Analysis of variance and the Tukey test were used to evaluate the data (p=0.05).

Results

Groups 1 and 4 had the highest and the lowest values of microleakage respectively. Microleakage of Panavia F2.0 cement was lower than for Core Max II and for both cements using adhesive made the microleakage smaller than without it (p<0.05).

Conclusion

Application of adhesive using Core Max II cement and Panavia F2.0 cement is strongly recommended to decrease microleakage. Self-etch adhesive performed better than total-etch adhesive.

Clinical Significance

With regards to microleakage, the self-etching primer displayed better sealing than that obtained with the totaletching, two-step dental adhesive.

Authors: Al-Dwairi Ziad Nawaf , Darwazeh Azmi Mohammad-Ghaleb , Al-Zwairi Abd Al-Wahab
Published: July 2019

Aim

The aim of this study was to assess and compare the quantitative and qualitative oral colonization of Candida species between a group of healthy tobacco smokers and a comparable group of nonsmokers, and to investigate a possible correlation between oral candidal colonization and the quantity or duration of the smoking habit.

Methods and Materials

Fifty smokers and 50 nonsmokers were included in the study. Candida species were isolated using the concentrated oral rinse (COR) technique and identified using the germ tube test and API 20 C AUX yeast identification system.

Results

Overall candidal transmission was 84 percent. Candida species were isolated from 42 (84 percent) of the smokers and 37 (74 percent) of the nonsmokers (p>0.05). The mean CFU/ml were 333 (SD=358) and 268 (SD=332), respectively (p>0.05).

Conclusion

Tobacco smoking did not appear to increase oral colonization with Candida species in healthy subjects.

Clinical Significance

The effects of smoking on oral tissues and the mechanisms by which Candida proliferate intra-orally as a result of cigarette smoking warrant additional study.

Direct Resin Composite Restorations versus Indirect Composite Inlays: One-Year Results
Authors: Mendonça Juliano Sartori , Lauris José Roberto Pereira , de Lima Navarro Maria Fidela , Neto Ranulfo Gianordoli , Santiago Sérgio Lima , de Carvalho Ricardo Marins
Published: July 2019

Aim

The aim of this study was to evaluate the clinical performance of direct resin composite restorations (Tetric Ceram-TC) and indirect composite inlays (Targis-TG) after 12 months.

Methods and Materials

Seventy-six Class I and II restorations (44 direct and 32 indirect) were inserted in premolars and molars with carious lesions or deficient restorations in 30 healthy patients according to the manufacturer's instructions. Each restoration was evaluated at baseline and after 12 months according to the modified USPHS criteria for color match (CM), marginal discoloration (MD), secondary caries (SC), anatomic form (AF), surface texture (ST), marginal integrity (MI), and pulp sensitivity (PS). Data were analyzed by Fisher and McNemar Chisquare tests.

Results

No secondary caries and no pulpal sensitivity were observed after 12 months. However, significant changes in marginal discoloration (MD) criteria could be detected between baseline and one-year results for both materials (p<0.05). For marginal integrity (MI) criteria, the differences between baseline and oneyear recall were statistically significant (p<0.05). For marginal integrity (MI) criteria, Tetric Ceram (TC) showed results statistically superior to Targis (TG) in both observation periods (p<0.05). No statistically significant changes in color match (CM), anatomic form (AF), or surface texture (ST) appeared during the observation periods (p>0.05).

Conclusions

Direct resin composite restorations performed better than indirect composite inlays for marginal integrity, but all restorations were judged to be clinically acceptable.

Clinical Significance

Tetric Ceram direct restorations and Targis indirect inlays in posterior teeth provide satisfactory clinical performance and the comparison between them showed little difference after one year.

Trends in Extraction of Permanent Teeth in Private Dental Practices in Kerala State, India
Authors: Anand Pradeep S. , Kamath Kavitha P. , Nair Balakrishnan
Published: July 2019

Aim

The aim of the present study was to identify the trends in tooth loss among patients attending four general dental practices in the south Indian State of Kerala.

Methods and Materials

The reasons for extraction of permanent teeth among patients who had attended the four clinics during a one-month period were categorized as follows: (1) dental caries and their sequelae, (2) periodontal disease, (3) orthodontic, (4) impactions, (5) prosthodontic, and (6) other reasons.

Results

A total of 997 permanent teeth were extracted, of which 445 (44.6 percent) teeth were extracted due to dental caries and their sequelae, 331 (33.2 percent) teeth due to periodontal disease, 111 (11.1 percent) teeth for orthodontic purposes, 25 (2.5 percent) teeth due to impactions, 25 (2.5 percent) teeth for prosthodontic purposes, and 60 (6 percent) teeth for other reasons.

Conclusion

The results of the present study suggest that dental caries and periodontal disease were the two major causes of tooth mortality in this particular patient population.

Clinical Significance

This is probably the first study to report on the trends in tooth loss in general practice in India. Similar studies should be conducted in other regions of the country to generate valuable data regarding the oral health patterns of the nation's population.

Are Flowable Resin-Based Composites a Reliable Material for Metal Orthodontic Bracket Bonding?
Authors: Rosa Vinicius , Pick Bárbara , Azeredo Tatiana Rocha , Filho Eduardo Augusto Mascarenhas Cruz , Júnior Walter Gomes Miranda
Published: July 2019

Aim

To compare the tensile bond strength (TBS) and adhesive remnant index (ARI) of three flowable resin-based composites and three orthodontic adhesive systems for metal bracket bonding.

Methods and Materials

Sixty bovine incisors were randomly divided into six groups. Enamel surfaces were etched with 37 percent phosphoric acid for 30 seconds and stainless steel orthodontic brackets were bonded using either flowable resinbased composites (3M Flow, FL; Tetric Flow, TF; and Wave, WA) or orthodontic bonding systems (Transbond XT, TX; Concise Orthodontic, CO; Fill Magic Ortodôntico, FM). All specimens were thermal cycled and stored in distilled water at 37°C for 24 hours, after which they were subsequently tested for TBS using a universal testing machine. ARI scores were determined after the failure of brackets. TBS and ARI data were submitted to ANOVA, Tukey, and Kruskal-Wallis tests (p=0.05), respectively.

Results

Rankings of the resin-based composites based on TBS means (MPa) were TX (6.4±2.1), followed by CO (4.5±2.7), FM (3.7±1.2), FL (3.6±1.2), TF (3.3±1.2), and WA (2.4±0.6). CO exhibited the lowest ARI mean score (0.9±1.2) which was significantly different from the other five materials: TX (2.8±0.42), FM (2.8±0.42), FL (2.9±0.32), TF (2.9±0.32), and WA (3.0±0.01). However, there were no statistically significant differences among the other groups with mean scores of 2.8–3.0. A score of 3.0 indicated that all the resin remained bonded to the tooth surface.

Conclusions

The flowable resin-based composites tested (Fl, TF, and WA) used to bond metal orthodontic brackets to bovine enamel had low mean TBS values but acceptable ARI mean scores.

Clinical Significance

Flowable composites may not be appropriate for bracket bonding, unless the teeth to be bonded are not subjected to higher orthodontic stresses, such as those without an antagonist.
