An In Vitro Evaluation of the Diagnostic Quality Ultra-Speed Versus Insight Intraoral Dental Film
Authors: Schiff Thomas , Solomon Brandy Egan
Published: July 2019

Twelve sets of FMS (full mouth survey) radiographs were taken by California licensed radiology technicians. Ten of the sets of FMS radiographs were taken using Ultra-Speed “D” film on the left side of the patient and Insight “F” speed film on the right side of the patient. The remaining two sets of films were taken using Insight Film on both sides of the patient to act as a control. Ten faculty members of the Diagnostic Department were asked to evaluate the twelve sets of FMS radiographs and report whether they had a preference for the right side, left side, or no preference. Criteria for preference were diagnostic ability and clarity of the films. The results of the study showed a preference for the right side (65.7%), which was imaged with Insight Film, compared to the left side (34.3%), which was imaged with Ultra-Speed Film.

Nickel and Cobalt Hypersensitive Reaction Before and After Orthodontic Therapy in Children
Authors: Saǧlam Aynur Medine Şahin , Baysal Vahide , Ceylan A. Murat
Published: July 2019

Nickel and cobalt are major components of alloys used in orthodontics. The objectives of this cross-sectional study was to determine the prevalence of a nickel hypersensitivity reaction before and after orthodontic treatment with conventional stainless steel brackets and wires. The total sample consisted of 82 patients (55 females, and 27 males) from the Orthodontic Department at the Faculty of Dentistry, Süleyman Demirel University. A patch test and a questionnaire were used to evaluate hypersensitivity to these metals. The statistical analysis was carried out using Fisher's exact X2 (2 x 2) test. The prevalence of nickel allergy was found to be higher in females than males (14.55% in females, 0% in males), and the prevalence of cobalt allergy was found to be 9.76% (7.27% in females, 14.81% in males). Orthodontic treatment with conventional stainless steel alloys does not appear to have an allergenic effect on the gingival and oral health of the patient. A family history of an allergy to these metals or the use of metallic objects in contact with the skin do not characterize nickel and cobalt hypersensitivity. This suggests orthodontic therapy with conventional stainless steel appliances does not initiate or aggravate a nickel hypersensitivity reaction. There was no association between the before treatment and after treatment to a nickel and cobalt hypersensitivity reaction.

Gender Differences in Dental Anxiety: Is the Chair Position Important?
Authors: Settineri Salvatore , Tati Filippo , Fanara Giusi
Published: July 2019

Dental anxiety in the general population is more prevalent in females than in males. The presence of dental anxiety was studied in a group of 189 females and 176 males using the following scales: the Dental Anxiety Scale (divided into DAS 1 containing 6 items, which explores a patient's dental anxiety and DAS 2 containing 13 items, which looks at dental anxiety concerning dentist-patient relations), the Self-Rating Depression Scale (SDS), and the Quality of Life Index (QL-Index). The results obtained showed significant differences only in relation to dental anxiety regarding the use of instruments (such as needles and handpieces) and the tilted-back position of the chair (DAS 1). No significant gender differences emerged between the two groups in relation to dental anxiety regarding dentist-patient relations (DAS 2), depression (SDS), and the quality of life (QL-Index). The results may explain why women avoid dental care and indicate new designs to make the chair position more comfortable would be useful.

A Clinical Evaluation of the Clinical Remount Procedure
Authors: Al Quran Firas A.M.
Published: July 2019

One hundred patients were treated with complete dentures. The patients were divided into two equal groups; the first group (50 patients) received complete dentures and a clinical remount procedure was performed, while the second group received complete dentures without a clinical remount. A four point, nine scale Patient Denture Satisfaction questionnaire was used to evaluate the patients’ satisfaction with their dentures. When the clinical remount procedure was used, results have shown a highly significant improvement in the comfort of the upper dentures and in the fit and comfort of the lower dentures. There was a significant improvement in the chewing ability as well. In conclusion it is highly recommended the clinical remount procedure be used because it improves the patient's satisfaction with their dentures in many important aspects as shown in this study.

Presence of Actinobacillus actinomycetemcomitans on the community Periodontal Index (CPI) Teeth in Periodontally Healthy Individuals
Authors: Shibli Jamil Awad , Cortelli Sheila Cavalca , Feres Magda , Figueiredo Luciene Cristina , de Oliveira Vanessa Padilha , Cortelli José Roberto
Published: July 2019

The aim of this study was to compare the prevalence ofActinobacillus actinomycetemcomitans(A. actinomycetemcomitans)located at Community Periodontal Index (CPI) teeth versus randomly selected teeth to determine if the CPI teeth are representative of this bacteria subgingival colonization in periodontally healthy young individuals. Forty-four individuals between 18 and 27 years of age were included in the study (mean age 23.11 ± 2.91 years). Pooled subgingival plaque samples were collected with paper points from the mesio-buccal aspect of the CPI teeth (10 teeth for adults and 6 teeth for persons under 20 years of age) and transported in reduced Ringer's solution to the culture medium. Sixty days following the first microbial analysis, new pooled microbial samples were obtained from the mesio-buccal aspect of 10 or 6 randomly selected teeth. The presence ofA. actinomycetemcomitanswas determined using a selective culture medium. Microbiological data were assessed by the Wilcoxon test (p < 0.05). A border line significance (p=0.51) was observed between CPI teeth and randomly selected teeth in terms of detecting the subgingival occurrence ofA. actinomycetemcomitans. CPI teeth showed to be representative ofA. actinomycetemcomitanssubgingival colonization. Therefore, these results suggest that in periodontally healthy young individuals, CPI teeth could be an appropriate source of samples for the subginginval detection of this pathogen.

Dentinal Hypersensitivity: A Review
Authors: Walters Patricia A.
Published: July 2019

Dentinal hypersensitivity is generally reported by the patient after experiencing a sharp pain caused by one of several different stimuli. The pain response varies substantially from one person to another. The condition generally involves the facial surfaces of teeth near the cervical aspect and is very common in premolars and canines. The most widely accepted theory of how the pain occurs is Brannstrom's hydrodynamic theory, fluid movement within the dentinal tubules. The dental professional, using a variety of diagnostic techniques, will discern the condition from other conditions that may cause sensitive teeth. Treatment of the condition can be invasive or non-invasive in nature. The most inexpensive and efficacious first line of treatment for most patients is a dentifrice containing a desensitizing active ingredient such as potassium nitrate and/or stannous fluoride. This review will address the prevalence, diagnosis, and treatment of dentinal hypersensitivity. In addition the home care recommendations will focus on desensitizing dentifrices.

Bone Marker Levels in Gingival Crevicular Fluid During Orthodontic Intrusive Tooth Movement: A Preliminary Study
Authors: Isik F. , Sayinsu K. , Arun T. , Ünlüçerçi Y.
Published: July 2019

The aim of the present study is to observe the changes in bone turnover markers, deoxypyridinoline (Dpd), osteocalcin, n-telopeptide (NTx), and bone alkaline phosphatase (balp) during the experimental orthodontic intrusion of maxillary premolar teeth. The study population required fixed appliance therapy involving the extraction of the maxillary first premolar teeth. Gingival crevicular fluid (GCF) samples were collected from each patient by using paper strips before the appliances were fitted and 1, 24, and 168 hours after the activation of appliances. After the second activation on the 21st, 22nd, and 28th days of the study, samples were collected. Enzyme-Linked Immunosorbent Assay (ELISA) tests were performed following manufacturer's recommendations. The results of the study indicate Dpd, osteocalcin, and balp values decrease with force application. Among the tested parameters only Dpd values showed statistically significant changes through time. One, 7, 22, and 28 day results show a significant amount of decrease when compared to 0 days. The extra decrease on the 22nd day (the day after the second activation) is also significantly lower. NTx crosslink values could not be detected in the experimental samples.

Cephalometric Evaluation for Saudi Population Using the Downs and Steiner Analysis
Authors: Al-Jasser Nasser M.
Published: July 2019

The purpose of this study is to formulate cephalometric norms of the Saudi population; and to evaluate whether significant cephalometric differences exist between Saudi and Caucasian patients. Lateral cephalometric radiographs of 60 selected Saudis (30 males and 30 females) with esthetically pleasing and harmonious faces, Angle I molar relationship, with all permanent teeth present and no history of orthodontic treatment or facial trauma, age range between 20 and 30 years were analyzed using the Downs and Steiner analysis. The means, standard deviations, and ranges of the measurements were compared with the norms established by Downs and Steiner. Statistically, several significant differences were noticeable in the results of the present study when the cephalometric mean values for the selected Saudi population were compared with the norms suggested for a white Caucasian population by Downs and Steiner. The results of the present study are significant and showed normal Saudis have a slightly protrusive maxillae, a tendency to Class II facial pattern, and a high mandibular plane angle. These results have clinical implications in the diagnosis and treatment of adult Saudis with dentofacial deformities.

Evaluation of drug prescriptions written over a six-month period.

Setting

Dental Hospital, Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria.

Subjects

Retrospective analysis of 313 prescriptions written by dentists attending to outpatient dental patients.

Results

The total number of drugs on one prescription ranged from one to seven with Penicillins being the most commonly prescribed drug. Some prescriptions were found to be incorrect with regards to dose, frequency, and duration. Instructions as to the best time of administering drugs with regards to meals were not stated in any prescription.

Conclusion

Improvement through continuing education is desired on the part of prescribers to ensure a good standard of care and avoid practices that may increase antimicrobial resistance. Drug information services including side effects and drug interactions for professionals and consumers at the hospital is highly desirable.

Dental Anxiety Among Patients Undergoing Various Dental Treatments in a Nigerian Teaching Hospital
Authors: Udoye Christopher I. , Oginni Adeleke O. , Oginni Fadekemi O.
Published: July 2019

The aim of the present study is to evaluate the levels of dental anxiety among patients undergoing various dental treatments and to compare the anxiety levels with those of similar studies conducted with subjects from different socio-cultural backgrounds. Dental anxiety was evaluated by the administration of a questionnaire based on the Corah's Dental Anxiety Scale (DAS). Student t-test and analysis of variance (ANOVA) with Bonferoni correction was employed to compare the mean DAS scores. Females recorded higher total DAS scores than males (7.49 ± 2.96 and 7.16 ± 3.44, respectively). Patients in the 24-34 year age group showed the highest total DAS scores (8.25 ± 3.20) followed by the <24 year age group. The total DAS scores for age groups 35-39 and >50 years differ significantly from those of age groups <24 and 24-34 years. The highest DAS score was recorded for root canal therapy (9.30 ± 2.84) followed by extraction. The level of dental anxiety among this study population is lower than those reported elsewhere. The observed avoidance of dental treatment among Nigerians, despite the seemingly low mean DAS scores, may be related to dental anxiety. The authors are, however, of the opinion poor dental awareness may be a contributory factor.

Surgical Wafers: A Comparative Study
Authors: Vachiramon Amornpong , Bamber M. Anwar
Published: July 2019

A comparative study of occlusal wafers for orthognathic surgery made for 185 orthognathic surgery patients with the mean age of 24.4±4.3 years is presented. This study is intended to highlight any wafer-associated surgical problems, which determine wafer design. Various types of occlusal wafers were used during the period of this review, but in most of the cases a simple quick-cure acrylic wafer was found to be most satisfactory. However, some difficult patients with cleft palates or neuromuscular disorders may require wafers of a novel design and material.

Plaque Removal Efficacy of a Prototype Manual Toothbrush versus an ADA Reference Manual Toothbrush with and without Dental Floss
Authors: Biesbrock Aaron R. , Bartizek Robert D. , Bsoul Samer A. , Terezhalmy Geza T.
Published: July 2019

Objective

The objective of this study was to compare the plaque removal efficacy of a prototype manual Deep Clean toothbrush versus an American Dental Association (ADA) manual toothbrush and the ADA manual toothbrush in conjunction with floss.

Methods

This study was a randomized, examiner-blind, six-period cross-over, single-center study conducted in 60 adult subjects that examined plaque removal with a prototype Deep Clean manual toothbrush, an ADA reference manual toothbrush, and an ADA reference manual toothbrush followed by floss. During the course of this study, subjects used each treatment two times. Plaque was scored before and after brushing using the Rustogi Modification of the Navy Plaque Index. A mixed model analysis of covariance (ANCOVA) for a crossover design with baseline plaque score as the covariate was applied to the baseline minus one-minute post-brushing differences in average whole-mouth plaque scores. Supplemental analyses were also performed using the ANCOVA model separately for average gingival margin scores and for average interproximal scores, using the appropriate baseline score as the covariate. All comparisons were two-sided at the 0.05 level of significance.

Results

The prototype Deep Clean manual toothbrush delivered an adjusted (via ANCOVA) mean difference between baseline and post-brushing plaque scores of 0.245, while the ADA manual toothbrush plus floss delivered an adjusted mean difference of 0.207 versus 0.196 for the ADA manual toothbrush alone. The prototype Deep Clean manual toothbrush demonstrated a statistically significantly greater reduction in plaque than the ADA manual toothbrush plus floss (p<0.001), which in turn had a statistically significantly greater reduction in plaque than the ADA manual toothbrush alone (p<0.001). The prototype Deep Clean manual toothbrush group had, on average, 25.2% and 18.3% greater plaque removal scores than the ADA manual toothbrush alone and the ADA manual toothbrush plus floss groups, respectively. Results for the interproximal and gingival margin regions also demonstrated statistically significantly (p<0.001) greater plaque removal for the prototype Deep Clean manual toothbrush group relative to the other groups.

Conclusions

The prototype manual Deep Clean toothbrush was found to deliver greater plaque removal by 25.2% and 18.3% compared to the control manual toothbrush group (ADA reference manual toothbrush) and ADA manual toothbrush plus floss group.

Influence of Zinc-Oxide Eugenol, Formocresol, and Ferric Sulfate on Bond Stength of Dentin Adhesives to Primary Teeth
Authors: Sakanam Fouad Saad
Published: July 2019

This study evaluated in vitro the influence of a temporary filling {zinc oxide-eugenol (ZOE)} and two pulpotomy agents {formocresol (FC) and ferric sulfate (FS)} on shear bond strength (SBS) of two dentin adhesives to the dentin of primary molars. A total of 80 dentin surfaces were prepared and randomly allocated into 10 groups of 8 specimens each. Groups were subjected to different treatments, which included covering with a paste of ZOE mixed at different powder:liquid (P:L) ratios, placement on a gauze soaked in FC or FS, or they received no pretreatment and served as a control. XRVTM Herculite® composite cylinders were bonded to dentin surfaces using Prime and Bond® NT adhesive resin or Opti Bond Solo Plus adhesive resin. SBSs were determined using the lnstron® testing machine running at a crosshead speed of 0.5 mm/min. The use of ZOE mixed at the lower P:L ratio of 10g:2g significantly decreased the values of SBS of the two adhesives. The use of two pulpotomy agents (FC and FS) significantly decreased the SBS of the two adhesives. The bond strength to dentin of primary teeth was influenced by the pulpotomy agents used and the ZOE P:L ratio but not by the adhesive system used.

Tobacco Cessation for the Dental Team: A Practical Guide Part 1: Background & Overview
Authors: Davis Joan M.
Published: July 2019

Dental professionals are strategically placed to be the leaders in tobacco prevention and cessation as they provide preventive and therapeutic services to a basically healthy population on a regular basis. By expanding the dental exam, diagnosis, and treatment to include tobacco cessation, a potentially life saving element of care is added to an established service. In addition periodontal disease and the potential for oral cancer mandate the inclusion of tobacco cessation services into dental care. Though dental professionals are aware of the health issues associated with tobacco use, they often feel ill prepared or uncomfortable presenting patients with a clear cessation message.

In this, the first of a two-part article, the purpose is to provide dental professionals with the foundational knowledge necessary to provide effective tobacco cessation as a normal part of patient care.

Rehabilitative Management Offered Nigerian Localized and Generalized Aggressive Periodontitis Patients
Authors: Dosumu Oyekunle Oluwole , Dosumu Elizabeth Bosede , Arowojolu Modupeola Olayinka , Babalola Sunday Samson
Published: July 2019

This paper highlights the typical clinical features of aggressive periodontitis (formerly known as juvenile periodontitis in the South Western region of Nigeria), the attending psychological effect following tooth loss, and the rehabilitative management offered which included periodontal therapy, psychotherapy, and prosthetic replacement of the missing teeth. The psychotherapy is the main distinguishing treatment in this study from previously reported modes of management of this disease entity.

Subjects were from a part of the South Western region of Nigeria, and ages ranged from 15 to 22 years. They all presented very late with subsequent gross periodontal breakdown and subsequent psychological depression. The mean values of the probing depth (mm), degree of mobility, and the amount of bone fill (mm) from the periapical radiographs were recorded pre and post-operatively. The missing teeth were replaced with acrylic dentures, and psychotherapy was offered at three levels (individual, group, and conjoint-family psychotherapy).

There was significant improvement of these clinical parameters six months after treatment, and the partial denture replacement of the missing teeth improved their appearance as expected but did not totally improve the initial depressive state. The psychotherapy offered gave the patients positive psychological effects that further restored their ability to socialize in their environment, which added to their positive experience of life.

In conclusion the typical clinical features of localized aggressive periodontitis (LAP) and generalized aggressive periodontitis (GAP) patients in our environment are late presentation with gross periodontal tissue breakdown. Psychotherapy is an important aspect in the management of this group of patients in conjunction with the periodontal and prosthetic management, which gives total rehabilitation.

Hyperlipidemia in Patients with Periodontitis
Authors: Moeintaghavi Amir , Haerian-Ardakani A. , Talebi-Ardakani Mohammadreza , Tabatabaie I.
Published: July 2019

Background

Periodontitis is a bacterial infection, which has been classified as a local chronic inflammation. This, as well as cardiovascular disease, may share common risk factors such as smoking, diabetes, behavioral factors, aging, and male gender. The aim of this study was to evaluate the association between hyperlipidemia and periodontitis.

Materials & Methods

The levels of plasma lipids in 40 subjects with periodontitis (CPITN score III or IV, pocket depth 4 mm) with mean age 32.3 ±1.2 years were measured and compared with those obtained from 40 age and sex matched controls. Both groups were systemically healthy according to their medical history.

Results

Total cholesterol (CHL) and triglycerides (TG) were significantly higher in the case group (P=0.045 and P=0.016, respectively). HDL and LDL cholesterols were higher in patients but did not have any significant differences with controls. The frequency of persons with pathologic values of TG and CHL were significantly higher in cases compared with controls.

Conclusions

These results showed hyperlipidemia may be associated with periodontitis in healthy people. However, it is unclear whether periodontitis causes an increase in levels of serum lipids or hyperlipidemia is a risk factor for both periodontitis and cardiovascular disease.

Fetal Alcohol Syndrome: Anthropometric and Oral Health Status
Authors: Naidoo Sudeshni , Chikte Usuf , Laubscher Ria , Lombard Carl
Published: July 2019

The purpose of this study was to analyze the anthropometric measures and oral health status of children with fetal alcohol syndrome (FAS) and compare them to matched controls. The sample of 90 cases (children diagnosed with FAS) and 90 controls were matched for age, gender, and social class. The mean age of the cases was 8.9 years with the controls slightly older at 9.1 years. The results of the anthropometric measurements in respect of weight, height, and head circumference showed significantly lower values for the FAS children when compared to the controls. Several physical abnormalities described in children with FAS were seen in this study. Some of these abnormalities seen in the FAS children included deformities in the small joints of the hand, altered palmar creases, and malformation of the ears.

The prevalence of enamel opacities between FAS and controls was not significantly different and averaged around 15% for both groups. More than three quarters of both the cases and the controls demonstrated the presence of plaque and almost two-thirds demonstrated gingival bleeding on probing. FAS patients had statistically significantly (p<0.001) more dentofacial anomalies than the controls. The mean decayed, missing, and filled teeth (dmft) score for the FAS sample was slightly higher, though not significantly different from that of the controls, and the decayed component (d) made up the largest part of the index in both groups.

Effects of Nd: YAG Laser Irradiation on the Adaptation of Composite Resins to Root Dentin
Authors: Maden Murat , Görgül Güliz , Tinaz A. Cemal , Kivanç Bağdagül H. , Ulusoy Özgür like Atasoy
Published: July 2019

One of the most important goals of the restoration of endodontically treated teeth with a composite resin post system is to achieve good adaptation of the composite material to dentin walls to prevent microleakage apically and coronally. In post core systems, to avoid microleakage between the dentin wall and resin material, laser irradiation may seem to be an alternative therapy for increasing adaptation quality.

The aim of this study was to investigate the adaptation of a packable composite resin to lased root canal dentin when it was used as post material.

Forty-five freshly extracted human teeth were selected and post spaces were prepared. The teeth were divided into three groups. In group 1 the dentin of the post spaces were etched with 35% phosphoric acid, in group 2 the dentin surfaces were irradiated with an Nd: YAG laser, and in group 3 the dentin surfaces were initially treated with the laser and then etched. The teeth of all groups were obturated with a bonding agent and composite. The groups were divided into two subgroups: a group for the scanning electron microscope (SEM) study and a group for the microleakage study.

The lased group showed poor adaptation and more microleakage was detected (p<0.05; variance analysis). The laser beam and acid-etching showed no advantage compared to the acid-etching alone (p>0.05).

The Nd: YAG laser irradiation adversely affects adhesion to dentin for using composite resin as a post material and does not constitute an alternative to acid-etching.

The Color Differences Between Different Thicknesses of Resin Veneered Over Amalgam
Authors: Al-Jazairy Yousra Hussain , El-Hejazi Ahmed A.
Published: July 2019

Statement of Problem

Composites and compomers are popular in dental practice. However, little is known about their esthetic appearance as veneering restorative materials over amalgam restorations.

Purpose

Thisin vitrostudy was designed to assess the color differences of composite and compomer restorative materials, placed in thicknesses of 1 mm and 2 mm over amalgam.

Material and Methods

Thirty six cylindrical Teflon molds were filled with amalgam (13 mm diameter, 2 mm thickness) and stored at 37°C and 100% relative humidity for 7 days. Nine veneers (for each thickness of 1 and 2 mm) were fabricated from four types of tooth-colored restorative material, Dyract AP (DYR), Compoglass F (COMP), Herculite XRV (XRV), and Vitalecense (VIT), over amalgam specimens using Teflon-split molds and following the manufacturers’ instructions. A spectrophotometer was used to measure the color difference ΔE* between the two thicknesses.

Results

Color difference ΔE* values for 1 mm thickness veneers [XRV (2.52), Comp (5.46), VIT (6.73), and DYR (6.88)] were statistically significantly higher than the 2 mm thickness [XRV (1.32), Comp (3.24), VIT (4.89), and DYR (4.83)]. Although the XRV material had the lowest ΔE* values, no statistically significant difference was found between the two thicknesses. The color measurements at L*, a*, and b* showed most materials became darker in color at either thickness.

Conclusion

The thicker veneer specimens were found to be closer in color to the controls than the thinner specimens. Only XRV had color differences (ΔE*) small enough to be considered clinically acceptable (2.52 and 1.32 at 1 mm and 2 mm, respectively).

Clinical Implications

In thisin vitrostudy the color of XRV was affected the least when veneered on amalgam. Opaquers may be needed to be used with thinner veneers to minimize the effect of amalgam background.

Physical Properties of Four Acrylic Denture Base Resisns
Authors: Meng Thomas R. , Latta Mark A.
Published: July 2019

Resistance to impact fracture and high flexural strength are desirable properties of denture base acrylics. The purpose of this laboratory study was to determine the Izod impact strength, the flexural strength, the flexural modulus, and the yield distance for four premium denture resins. Bar specimens 86 x 11 x 3 mm of Lucitone 199, Fricke Hi-I, ProBase Hot, and Sledgehammer Maxipack were fabricated following the manufacturer's instructions for heat processing. The bars were surface finished using silicon carbide paper to 600 grit. Ten specimens from three lots of each material were made (n=30). Flexural strength, flexural modulus, and yield distance were determined by testing the specimens to failure using a three-point test fixture. Izod impact strength was determined using an Izod tester on un-notched specimens generated from the flexural test (n=60). Analysis of variance (ANOVA) and post-hoc Tukey's test were used for statistical comparison of each property. There were significant differences in the physical properties among the denture acrylics tested. Lucitone 199 demonstrated the highest impact strength, flexural strength, and yield distance (p<0.05). Lucitone 199 with an Izod impact strength of 5.5 ± 1.2 N·m, a flexural strength of 99.5 ± 4.5 MPa, and yield distance of 9.9 ± 0.76 mm exhibited statistically greater results than Fricki Hi-I, ProBase Hot, and Sledgehammer Maxipack. Fricki Hi- I with a yield distance of 7.3 ± 1.1 mm was statically greater than ProBase Hot and Sledgehammer Maxipack. Fricki Hi-I, ProBase Hot, and Sledgehammer Maxipack were statistically similar for the Izod impact strength and flexural strength tests performed. ProBase Hot and Sledgehammer Maxipack yielded statistically similar results for all tests performed. Flexural modulus had an inverse relationship to the impact strength, flexural strength, and yield distance.

Outcome of Endodontic Treatment of Teeth Filled Using Lateral Condensation versus Vertical Compaction (Schilder's Technique)
Authors: Aqrabawi Jamal A.
Published: July 2019

The purpose of this prospective clinical and radiographic investigation was to assess the treatment results following endodontic therapy of teeth filled with lateral condensation versus teeth filled with vertical compaction of warm gutta-percha. A total of 290 patients were treated using the standardized step-back technique for canal preparation, which were filled with either lateral condensation or vertical compaction in one single session. Five years later, the treatment results were assessed clinically and radiographically and related to the type of the obturation technique using Chi-square analysis. Of the 340 teeth that were reexamined, 160 teeth were filled with lateral condensation, and 180 teeth were filled with vertical condensation. The results showed a significantly higher success rate for the vertical compaction versus the lateral condensation technique of teeth presented with preoperative periapical lesions P<0.04. Regardless of the preoperative periapical status of the teeth, no statistically significant difference was found between the two techniques. The overall success rate of both filling techniques was 80.3%.

Brushing Effect of Abrasive Dentifrices during At-home Bleaching with 10% Carbamide Peroxide on Enamel Surface Roughness
Authors: Martins Luís Roberto Marcondes , Worschech Claudia Cia , Rodrigues José Augusto , Ambrosano Gláucia Maria Bovi
Published: July 2019

During tooth bleaching abrasive dentifrices might change the outer superficial enamel. The aim of this in vitro study was to evaluate the roughness of human enamel exposed to a 10% carbamide peroxide bleaching agent at different times and submitted to different superficial cleaning treatments. The study consisted of 60 sound human enamel slabs, randomly assigned to different treatment groups: G1 - not brushed; G2 - brushed with a fluoride abrasive dentifrice; G3 - brushed with a non-fluoride abrasive dentifrice; and G4 - brushed without a dentifrice. There were 15 enamel slabs per group. Slabs of molar teeth were obtained and sequentially polished with sandpaper and abrasive pastes. A perfilometer was used to obtain the mean of Ra value on the surface of each specimen to initial and experimental times. Bleaching was performed on the enamel surface for six hours daily. After that, each slab received a cleaning surface treatment and was stored in artificial saliva. Analysis of variance (ANOVA) and Tukey's HSD hoc analysis (α =0.05) revealed significant differences in roughness values over time for enamel bleached and treated with different superficial cleaning methods. G1 and G4 showed no significant differences in roughness over time, G2 and G3 showed a significant increase in the surface roughness values. This in vitro investigation showed the sole use of 10% carbamide peroxide did not alter the enamel surface roughness, but the cleaning treatments that employed the use of brushing with abrasive dentifrices resulted in a significant increase of enamel surface roughness.

Authors: Al-Malik Manal Ibrahim , Al-Sarheed Maha Abdulla
Published: July 2019

The aims of this study were to determine the characteristics of patients and type of dental treatment carried out using dental general anesthesia (DGA) during two years in a following three year period. A total of 182 patients received treatment between 1999 and 2001. The mean age was 4.9 years. The main indication for DGA was behavior management problems. Complete oral rehabilitation including complex restorative treatment and extractions was provided under DGA at a single visit. Failure to return for recalls was common; 83% of patients returned for the post-operative recall but only 26% after a three year period. Most of the patients requiring further treatment accepted it in the dental chair. Only one patient received a second DGA during the three years following treatment.

Efficacy and Safety of a Novel Stabilized Stannous Fluoride and Sodium Hexametaphosphate Dentifrice for Dental Hypersensitivity
Authors: Schiff Thomas , He Tao , Sagel Lisa , Baker Robert
Published: July 2019

Purpose

Dentinal hypersensitivity is a common complaint among dental patients. Recently, a novel 0.454% stabilized stannous fluoride dentifrice containing sodium hexametaphosphate (SHMP) was introduced that offers a desensitizing benefit. This trial was conducted to assess the desensitizing efficacy of this new dentifrice relative to a sodium fluoride control dentifrice.

Methods and Materials

This was a double-blind, parallel-group, randomized clinical trial conducted according to the American Dental Association (ADA) Guidelines for the Acceptance of Products for the Treatment of Dentinal Hypersensitivity. Ninety subjects who met the entrance criteria were stratified based on age, gender, and baseline sensitivity scores and randomly assigned to either the stabilized stannous fluoride + SHMP dentifrice (Crest®Pro-Health) or the sodium fluoride control dentifrice. Subjects were instructed to brush twice daily for eight weeks. Efficacy assessments were made, including tactile (Yeaple probe) and thermal (Schiff Air Index) sensitivity, and an oral soft tissue examination was conducted at baseline, week four, and week eight.

Results

The mean sensitivity score based on the Schiff Air Index for the stannous fluoride + SHMP group was statistically significantly lower than that of the control group, at both weeks four and eight (P < .0001). At week eight, the stannous fluoride + SHMP dentifrice group had an adjusted mean 44% lower than that of the control group. The mean tactile sensitivity score for the stannous fluoride + SHMP group was statistically significantly higher, indicating a reduction in sensitivity, than that of the control group, at both weeks four and eight (P < .0001). At week eight, the stannous fluoride + SHMP dentifrice group had a mean desensitizing improvement of 71% greater than the control.

Conclusion

The stabilized stannous fluoride + SHMP dentifrice provided statistically significant reductions in dentinal hypersensitivity at four and eight weeks compared to the sodium fluoride control dentifrice.

Authors: Al Quran Firas A. M. , Al-Dwairi Ziad N.
Published: July 2019

Aim

To determine the prevalence of tori in Jordanian edentulous patients, the sex variation in their distribution, and their clinical characteristics.

Methods

Three hundred and thirty eight patients were examined in the Prosthodontic Clinic in the Department of Restorative Dentistry at Jordan University of Science and Technology. The location, extent, and clinical presentation of tori were recorded related to the age and sex of patients.

Results

The overall prevalence of tori was 13.9%. The prevalence of torus palatinus was 29.8% (14/47), while that of torus mandibularis was significantly higher 42.6%(20/47). Both types of tori were associated with each other in 27.7% of cases (13/47).

Conclusions

There was no significant difference in the prevalence of tori between males and females. There seems to be a strong association between mandibular and palatal tori.

Comparative Clinical Evaluation of Acellular Dermal Matrix Allograft and Connective Tissue Graft for the Treatment of Gingival Recession
Authors: Rahmani M.E. , Rigi Lades Mohammad A.
Published: July 2019

Aims

“Gingival recession is a condition reported to occur due to abnormal periodontal anatomy, poor hygiene, excessive occlusal forces, toothbrush abrasion, and even iatrogenic or factitious causes. Though various surgical techniques are available to treat this problem, the most common is the palatal soft tissue autograft. Recently, an acellular dermal matrix allograft (ADMA) has been available as a substitute for the palatal tissue harvest. The aim of this study is to compare the ADMA with the conventional subepithelial connective tissue graft (SCTG) in the treatment of gingival recession.”

Methods and Materials

Fourteen patients with 20 gingival recessions of Miller's grade I and II were selected and randomized in two groups of control (SCTG) and test (ADMA). In each group ten recession defects were treated. The following parameters were measured at baseline and then at six months post surgery: recession height (RH), recession width (RW), probing depth (PD), attached gingiva (AG), keratinized gingiva (KG), and clinical attachment level (CAL). All parameters were analyzed using the two-sample t-test. Data analysis was performed using SPSS (version 11) software.

Results

The following mean changes (mm) occurred in SCTG and ADMA, respectively: 2.60±0.97 and 2.90±0.81 decrease in RH; 1.70±1.01 and 1.65±0.67 decrease in RW; 2.50±0.97 and 2.95±0.69 increase in KG; 2.25±0.92 and 2.65±0.85 increase in AG; 2.60±1.08 and 2.75±0.92 decrease in CAL; and finally 0.05±0.50 and 0.10±0.46 decrease in PD for the SCTG and ADMA groups, respectively. The percentage of root coverage for the two groups was 70.12%±22.81% and 72.08%±14.12%, respectively. The changes from baseline to the six-month visit were significant for both groups in terms of all parameters but PD. However, the differences in mean changes were not significant between the two groups in any of the parameters.

Conclusion

These findings imply the ADMA and SCTG techniques could produce the same results when used for the successful treatment of gingival recessions. In addition the ADMA could be used as an adequate alternative treatment modality for conventional techniques.

Evaluation of Swallowing Patterns of the Tongue Using Real-time B-mode Sonography
Authors: Ardakani Fatemah Ezoddini
Published: July 2019

The aim of the present study was to evaluate the swallowing patterns of the tongue using B-mode sonography. A total of 65 patients aged between eight and 35 years were enrolled in the study including 25 controls. The swallowing patterns of the 40 patients were divided into groups of ten normal, 12 inconsistent, and 18 abnormal. Eight patients with a swallowing abnormality had Angle Class I occlusions, two had Class II, and the remaining ten patients had Class III. The majority of abnormal or inconsistent swallowing patterns were found in cases of mandibular prognathism. Quantitative data was not analyzed in this study. The results of this study show that B-mode sonography, being a non-invasive procedure permitting direct visualization of the movements of the tongue in both coronal and sagittal planes, can be used with certainty for diagnosing swallowing abnormalities.
