Authors: Shinohara Elio Hitoshi , Cheng Cheong Kuo , Gaia Bruno Felipe , de Oliveira Neto Humberto Gomes , Martini Marcelo Zillo , Aburad Arlindo
Published: July 2019

Background

Surgical procedures under local anesthesia are routinely employed by the dentist and are susceptible to significant complications which demand immediate care from the dental professional.

Report

This report presents a case of severe arterial hemorrhage during a simple removal of a lesion during an incisional biopsy.

In the event of severe arterial hemorrhage in a conventional dental office, manual compression for containing the hemorrhage and use of an adequate light source to correctly visualize the origin of the bleeding is recommended. If visible, the dental surgeon must attempt to perform vascular ligature or an occlusive suture. If the hemorrhage cannot be controlled after these measures, the patient must be transported to a hospital while continuing local compression during transit.

Effects of an In-office Bleaching System (ZOOM™) on Pulp Chamber Temperature In Vitro
Authors: Yazici A. Rüya , Kugel Gerard , Khanbodaghi Azita
Published: July 2019

Aim

Several new techniques and materials for in-office bleaching have been introduced recently. The aim of this in vitro study was to measure the temperature increase in the pulp chamber of extracted teeth produced by the Zoom!™ in-office bleaching system and to investigate the influence of this light in conjunction with the bleaching gel on pulp temperature rise.

Methods and Materials

Ten extracted, caries-free, unrestored human maxillary central incisor teeth were used for the study. The root of each tooth was cut approximately 2-3 mm apical to the cementoenamel junction (CEJ), and the apical orifice of the root canal was enlarged. The remaining pulp tissue was removed and the empty pulp chamber was filled with a heat sink compound. A thin K-type thermocouple was inserted into the pulp chamber through the cut root area. The root surfaces of the teeth were partially submerged in a water bath during the testing procedure at 37°C. A whitening gel containing 25% hydrogen peroxide was applied to the buccal surfaces of all ten teeth and exposed to a Zoom!™ activation light for twenty minutes for three times; this was designated as Group I. The same teeth were then exposed with the Zoom!™ light for the same time period without the application of the bleaching gel and designated as Group II.

The intrapulpal temperature pre-treatment (baseline) and the temperature increase during treatment was measured for both treatment groups.

Results

There was a statistically significant difference between the two groups (p=0.003). Application of the Zoom!™ light in conjuction with the application of bleaching gel produced a greater temperature rise than did the light alone. The mean temperature rise for Group I (light and bleaching gel) was 1.11°C (0.18°C) and 1.01°C (0.12°C) for Group II (light alone) at the end of a five-minute exposure.

Conclusion

The Zoom!™ light either used with or without bleaching gel showed no significant increase in the intrapulpal temperature of teeth when used for the recommended exposure time.

Giant Cell Lesions with a Noonan-like Phenotype: A Case Report
Authors: Filho Manoel Sant'Ana , Cancino Claudia Marcela H. , Gaião Léonilson , Oliveira Flavio Augusto Marsiaj
Published: July 2019

Aim

The purpose of this article is to describe a case of multiple giant cell lesions of the mandible that occurred in a 14-year-old girl with phenotypic characteristics associated with Noonan Syndrome (NS).

Background

NS is a dysmorphic disorder characterized by hypertelorism, short stature, congenital heart defects, short and webbed neck, skeletal anomalies, and bleeding diathesis.

Report

A 14-year-old girl with a previous diagnosis of NS (sporadic case) presented with multiple radiolucent lesions in the body and ramus of her mandible.

In terms of clinical behavior and the described radiographic characteristics, giant cells lesions with Noonan-like phenotype can be considered a form of cherubism. Therefore, surgical intervention is not necessary, but radiographic follow-up and observation is very important during the control and gradual regression of the lesions.

A Method of Gauging Dental Radiographs during Treatment Planning for Dental Implants
Authors: Anil Sukumaran , Al-Ghamdi Hamdan S.
Published: July 2019

Aim

The goal of pre-surgical dental implant treatment planning is to position the optimum number and size of implant fixtures to achieve the best restorative results. The purpose of this article is to describe the use of radiographic imaging software to calibrate and measure anatomical landmarks to overcome inherent distortions associated with dental radiographs. The procedure along with its potential use as an adjunct to radiographic interpretation in routine clinical implant practice is presented.

Background

Diagnostic imaging is an essential component of implant treatment planning, and a variety of advanced imaging modalities have been recommended to assist the dentist in assessing potential sites for implants. Although technological advances have resulted in new imaging innovations for implant dentistry, dental radiography remains the most widely used tool for determining the quantity and quality of alveolar bone as it is a non-invasive procedure. However, the unreliable magnification factor associated with conventional radiographs remains a major problem when estimating the amount of bone available at the implant site.

This image measurement technique is capable of assessing the bone quantity by measuring the height and width of the alveolar crest for a specified region in a two dimensional plane in any direction related to the visible landmarks in the oral cavity. These measurements can be used by the clinician to select the type of implant and its position. Since there is no additional equipment or cost involved, the technique can be used as an important adjunct in implant practice.

Dental Trauma: Restorative Procedures Using Composite Resin and Mouthguards for Prevention
Authors: Soares Carlos Jose , de Freitas Santos Filho Paulo César , Quagliatto Paulo Sérgio , Simamoto Paulo Cézar
Published: July 2019

Aim

The aim of this article is to describe a step-by-step protocol for emergency care of a patient with a dentoalveolar injury in the anterior region of the mouth as well as the fabrication of a mouthguard to prevent future trauma.

Background

Dental trauma is one of the most serious oral health problems in active children and adolescents. Care of traumatized patients requires immediate initial emergency treatment followed by integrated procedures to restore damaged oral structures along with a subsequent trauma prevention strategy. Dentoalveolar injuries in the anterior region of the mouth are often characterized by tooth avulsion and coronal fracture. They are managed using procedures such as dental splinting, endodontic therapy with its unique characteristics, and restorative techniques to re-establish function and esthetics as well as protective mouthguards.

Report

A 16-year-old male presented with avulsion of his maxillary central incisors as a result of a direct, unintentional impact with an opponent during a basketball game. The teeth had been stored in physiological serum immediately following the injury and the patient received immediate care. On clinical examination, the right central incisor was fractured at the incisal third of the crown but no bone fractures were found. The teeth were reimplanted and splinted. The fractured right central incisor was restored following endodontic treatment and a mouthguard was fabricated for the patient.

The dentist must be knowledgeable about the most efficient and suitable treatment for each traumatic scenario in order to provide appropriate care for dental injuries. Coordinated multi-disciplinary action is fundamental in the successful treatment of these injuries. The dental mouthguard is an effective device for protecting the teeth and supportive structures during physical activities and must be part of the protective equipment used by athletes. It is the responsibility of the dental professional to make parents, trainers, and athletic associations aware of the risks associated with physical activities without orofacial protection; this should encourage the proper use of all protective devices to prevent dentoalveolar injuries that compromise oral functions, esthetics, and increase the cost of healthcare.

Positioning Magnets on a Multiple/Sectional Maxillofacial Prosthesis
Authors: Goiato Marcelo Coelho , Fernandes Aline Úrsula Rocha , dos Santos Daniela Micheline , Baräo Valentim Adelino Ricardo
Published: July 2019

Aim

The aim of this report is to describe a quick and simple method of positioning retention magnets when deformed patients are rehabilitated with an oculopalpebral prostheses attached to a maxillary denture/obturator.

Background

In patients with deformities requiring complex rehabilitations, the use of magnets is the most efficient means of providing combined prostheses with retention quality and stability. Usually prostheses with magnets are in sections and have a magnet in each section. When the sections are put together properly, the magnets are attracted to each other and retain the sections.

Report

An edentulous patient presented for a post-surgical evaluation of a maxillofacial prosthesis used to repair a partial maxillectomy and left orbital exoneration which removed all adjacent tissues leaving an open communication between the oral, nasal, and orbital cavities. The proposed treatment plan included construction of a maxillary complete denture with a palatal obturator and a mandibular complete denture. Magnets were used to attach the oculopalpebral prosthesis to the maxillary denture/obturator.

Use of retention magnets simplify the clinical and laboratorial phase, retains the denture, and makes it stable and comfortable for the patient. This treatment is one successful approach to the restoration of oral function and increases the patient's quality of life.

A Method for Stabilizing a Lingual Fixed Retainer in Place Prior to Bonding
Authors: Al-Emran Sulaiman , Barakati Rakan
Published: July 2019

Aim

The objective of this article is to present a simple technique for stabilizing a lingual fixed retainer wire in place with good adaptation to the teeth surfaces and checking for occlusal interferences prior to the bonding procedure.

Background

Bonding of an upper or lower fixed lingual retainer using stainless steel wires of different sizes and shapes is a common orthodontic procedure. The retainer can be constructed in a dental laboratory, made at chair side, or it can be purchased in prefabricated form. All three ways of creating a fixed retainer are acceptable. However, the method of holding the retainer wire in place adjacent to the lingual surfaces of the teeth before proceeding with the bonding process remains a problem for some practitioners.

Report

The lingual fixed retainer was fabricated using three pieces of .010” steel ligature wire which were twisted into a single strand wire. Another four to five 0.010” pieces of steel ligature wires were twisted in the same way to serve as an anchor wire from the labial side of the teeth. The retainer wire was bonded using the foible composite.

The technique presented here for stabilizing the retainer wire prior to bonding provides good stabilization, adaptation, and proper positioning of the retainer wire while eliminating contamination of etched surfaces which might arise during wire positioning before bonding. This technique also allows the clinician the opportunity to check the occlusion and adjust the retainer wire to avoid occlusal interference prior to bonding maxillary retainers. This same clinical strategy can be used to stabilize wires for splinting periodontally affected teeth and traumatized teeth.

A Study of Temperature Rise in the Pulp Chamber during Composite Polymerization with Different Light-curing Units
Authors: Millen Christopher , Ormond Martyn , Richardson Gillian , Santini Ario , Miletic Vesna , kew Peter
Published: July 2019

Aim

The study compared pulp temperature rise during polymerization of resin-based composites (RBCs) using halogen and LED light-curing units (LCUs).

Methods and Materials

A total of 32 teeth extracted from patients aged 11-18 years were used in the study. Thermocouples placed on the roof of the pulp chamber using a novel ‘split-tooth’ method. In Group 1 a halogen LCU with a light intensity of 450 mWcm-2 was used and in Group 2, an LED LCU with a light intensity of 1100 mWcm-2 was used. The teeth were placed in a water bath with the temperature regulated until both the pulp temperature and the ambient temperature were stable at 37°C. Continuous temperature records were made via a data logger and computer. The increase in temperature from baseline to maximum was calculated for each specimen during the curing of both the bonding agent and the RBC.

Results

The rise in pulp temperature was significantly higher with the LED LCU than with the halogen LCU for bonding and RBC curing (p<0.05). The major rise in temperature occured during the curing of the bonding agent. During the curing of the RBC, rises were smaller.

Conclusions

Curing of bonding agents should be done with low intensity light and high intensity used only for curing RBC regardless of whether LED or halogen LCUs are used.

Impacted Mandibular Canines
Authors: Tozoglu Sinan , Yavuz Muhammet Selim , Aras Mutan Hamdi , Büyükkurt Mustafa Cemil
Published: July 2019

Aims

The aim of the present study was to investigate the incidence of impacted mandibular canines, the associated pathology of these teeth, and to classify them.

Methods and Materials

This is a retrospective cohort study of 5022 panoramic radiographs taken of patients who presented to the Oral and Maxillofacial Surgery Service of the Faculty of Dentistry at Ataturk University in Erzurum, Turkey between January, 1998 and March, 2006. The panoramic radiographs and clinical data were reviewed. Observations were made on the status of missing permanent mandibular canines; retained deciduous canines; side and number of mandibular canines; sex and age of patients; and any other associated pathology or symptoms as well as treatment methods employed.

Results

The incidence of mandibular canine impaction is 1.29% in the 5022 individuals of this Turkish subpopulation. A total of 65 patients had impacted mandibular canines with 33 being females and 32 males. In this study 41 impacted mandibular canines were extracted. Twenty-three canines were attached to bonded buttons for orthodontic eruption purposes. After surgical exposure, one impacted canine was transplanted and the others were left in place for observation.

Conclusions

Maxillary canine impaction is more frequent than mandibular canine impaction. Mandibular canine impaction incidence in this study was found higher than in the published literature to date. This result may be evidence of an actual increase of the number of impacted mandibular canine teeth among patients.

Determining Tooth Size Ratio in an Iranian-Azari Population
Authors: Mirzakouchaki Behnam , Shahrbaf Shirin , Talebiyan Reza
Published: July 2019

Aim

The aim of this investigation was to determine the tooth size ratio in an Iranian-Azari population.

Method and Materials

The Bolton tooth size analysis was performed on a sample of 50 plaster models (25 male subjects, 25 female subjects) of Iranian-Azari subjects. The mesiodistal widths of all teeth were obtained and the Bolton anterior ratio and overall ratio were calculated. The mean, range, and standard deviation were calculated for the anterior and overall ratio, and a coefficient of variation was obtained for the tooth size ratio.

Results

For the anterior ratio (3-3), the Iranian-Azari had a mean of 78.0 mm with a standard deviation of 3.1; the range was 73.68 to 84.6 mm. For the overall ratio (6-6), the mean was 92.0 mm with a standard deviation of 2.4; the range was 88.09 to 97.5 mm.

Conclusions

The results from the Iranian-Azari subjects in the study are similar to Bolton's original data for an American population. These values and the degree of variation were similar to the original data by Bolton, indicating the Bolton analysis for Caucasian samples can be transferred to an Iranian-Azari population. It also confirms no relevant sexual dimorphism exists, and these values are valid for both male and female subjects.

Clinical Inertia in Dentistry: A Review of the Phenomenon
Authors: Rindal D. Brad , Rush William A. , Boyle Raymond G.
Published: July 2019

Aim

Dentistry has been slow to adopt innovations in dental practice even when they are recommended by national organizations and supported by evidence-based guidelines. The objective of this review is to describe clinical inertia, a concept described frequently in the medical literature, and to use findings from tobacco cessation and dental sealant studies as evidence of its existence.

Methods and Materials

A review of the literature published during the past 30 years was conducted to determine the state of affairs of two very different areas of dental practice, tobacco cessation intervention and application of sealants, to demonstrate the concept of clinical inertia in dental practice. Factors such as over estimating services provided, unfounded reasons not to act, lack of adequate training, and competing demands that account for the inertia were examined.

Discussion

Clinical inertia is a complex concept that needs more attention in dentistry. A variety of strategies will be required to overcome it in order to provide the best care for the public.

Conclusion

Clinical inertia is a useful paradigm for explaining delays in the incorporation of new knowledge into clinical practice. It offers a model against which the broader dental community can develop and test strategies to reduce the delays in translating best practices into daily practices.

Clinical Significance

The path to providing state-of-the-art care for the public is to engage in the discovery, dissemination, and acquisition of new knowledge then transform it into evidence-based best practices to be used in daily clinical practice.

Fracture Resistance of Endodontically-treated Teeth Restored Using Three Root-reinforcement Methods
Authors: Kimyai Soodabeh , Moosavi Horieh , Maleknejad Fathemeh
Published: July 2019

Aim

The aim of this in vitro study was to compare the fracture resistance of endodontically-treated anterior teeth with their roots reinforced using three different restorative methods.

Methods and Materials

Forty sound maxillary human central incisors were randomly assigned to four groups (n=10). The crowns of the teeth were removed at a level 2 mm incisal to the cementoenamel junction (CEJ). After root canal therapy, flared canals were simulated in three groups. In the first, second, and third groups the flared canals were reinforced with resin composite (RCO) (Clearfil DC Core Automix), two Reforpins (REF), and a resin cement (RCE) (Panavia F 2.0), respectively. In the fourth (DEN) group flared canals were not created. The same size fiber reinforced composite (FRC) posts were cemented with resin cement (Panavia F 2.0) in all groups. After post cementation and restoration of the teeth crown with a core build-up composite (Clearfil Photo Core), the roots of the teeth were embedded in acrylic resin blocks up to 1 mm below the CEJ. The samples were loaded in an Instron testing machine with a crosshead speed of 0.5 mm/min at a 45° angle to the long axis of the tooth on the palatal surfaces until failure occurred. Data were analyzed using the Kruskal-Wallis, Mann-Whitney, and Chi-square tests (p=0.05).

Results

Significant differences were found between fracture resistance in all of the groups (P<0.05) with the exception being among the RCO and REF groups. The least mean value 230 (130) N and the highest mean value 830 (220) N were shown in the fracture resistance of the RCE and DEN groups, respectively.

Conclusion

Reforpin can be used as an alternative to resin composite for internal reinforcement of weakened roots according to the results of this study. For reinforcement of flared canals, fiber posts along with Reforpin or resin composite proved to have higher fracture resistance than resin cement. Non flared canals had the highest fracture resistance.

Instability of Self-esteem and Affective Lability as Determinants of Self-reported Oral Health Status and Oral Health-related Behaviors
Authors: Dumitrescu Alexandrina L. , Dogaru Beatrice C. , Dogaru Cristian D.
Published: July 2019

Aim

The aim of the study was to examine the impact of the instability of self-esteem and affective lability on students’ self-rated oral health and oral health-related behaviors.

Methods and Material

The present study sample consisted of 178 first year medical students. A questionnaire was used to collect information about socio-demographic factors, behavioral factors, self-reported oral health status, the instability of self-esteem, and affective lability.

Results

Significant differences were found on the instability of self-esteem and affective lability on the following variables: gender, smoking, anxiety, depression, stress in everyday life, number of extracted teeth, and satisfaction with appearance of one's own teeth (Ps<0.05). The level of instability of self-esteem had a consistent association with the self-reported oral health status and satisfaction with appearance of teeth. The affective lability total score was a determinant of the number of extracted teeth, last toothache, self-rated gingival status, while anger was correlated with the number of current non-treated caries, extracted teeth, toothbrushing, and flossing frequency.

Conclusions

The results indicate there is an increased risk for impaired dental health among subjects with instable self-esteem symptoms or symptoms of anger.

Osteonecrosis of the Jaws Secondary to Bisphosphonate Therapy: A Case Series
Authors: Kumar Satish K. S. , Meru Michael C. , Sedghizadeh Parish P.
Published: July 2019

Aim

The objective of this report is to present the clinical experiences of several patients affected with osteonecrosis (ONJ) secondary to bisphosphonate (BP) therapy and to provide a discussion of the specific BPs implicated in this condition.

Background

ONJ secondary to BP therapy is becoming an increasingly reported complication following dental therapy. This is particularly true of surgical dental procedures such as extractions. BPs are a class of pharmaceuticals used in the treatment of numerous disorders affecting bone, including osteoporosis, cancer metastases to bone, hypercalcemia of malignancy, and multiple myeloma. Although ONJ is a more recently described phenomenon, it is an emerging problem that may be associated with significant morbidity such as oral dysfunction, impaired eating ability, pain, and compromised esthetics resulting in a poor quality of life in affected patients.

Case Report

This is a description of 13 patients affected with ONJ secondary to BP therapy managed at the Orofacial Pain & Oral Medicine Center, Special Patients Clinic, and Oral and Maxillofacial Surgery Clinic at the University of Southern California, School of Dentistry between October 2005 and April 2007, with a discussion of the specific BPs implicated in this condition, the clinical presentation, management, and follow-up.

Thorough reporting of every case of ONJ is important to help advance the understanding of this poorly understood condition. The authors’ approach to care represents a more conservative mode to management than previously described by many investigators.

Re-attachment of Anterior Tooth Fragment using a Self-etching Adhesive: A Case Report
Authors: Ozel Emre , Cildir Alper , Ozel Yonca
Published: July 2019

Aim

The purpose of this case report is to describe the re-attachment of an anterior tooth fragment using a selfetching adhesive.

Background

Fracture of anterior teeth by trauma is a common problem in children and teenagers due to their active lifestyle. Restoration of these teeth often presents a challenge because of the large pulp in young teeth and open apical foramen depending on the age of the child. New dental adhesive materials offer an alternative solution for the treatment of some anterior tooth fractures.

Report

A 17-year-old female patient presented for treatment of a fractured maxillary left central incisor. The clinical examination revealed the exposure of dentin, but there was no exposure of the pulp. The patient saved the tooth fragment making it available for re-attachment to the remaining tooth structure. Under local anesthesia and rubber dam isolation the tooth fragment was re-attached using a self-etching adhesive and a microhybrid composite.

The re-attached tooth fragment was assessed clinically, radiographically, and using photographs at one, six, 12, 24, and 36 month intervals. The tooth remained vital, and there was no change in the color of the tooth at the three-year recall.

Canalicular Adenoma Presenting as an Asymptomatic Swelling of the Upper Lip: A Case Report
Authors: Azevedo Luciana Reis , Dos Santos Jean Nunes , De Lima Antônio Adilson Soares , Machado Maria Ângela Naval , Grégio Ana Maria Trindade
Published: July 2019

Aim

The purpose of this report is to present the clinical and histological features of a canalicular adenoma (CA) occurring in the upper lip and vestibular fornix of a 62-year-old woman.

Background

CA is an uncommon benign salivary gland tumor occurring almost exclusively in the intraoral glands. This tumor has often been referred to as a variant of the basal cell adenoma. However, the World Health Organization's latest histological classification of salivary gland tumors recognizes it as a separate entity under the broader heading of monomorphic adenoma, which is not related to any of the subtypes of basal cell adenomas.

Case Report

A 62-year-old woman with a chief complaint of an extraoral swelling in the upper lip. The evolution of the lesion was not known by the patient who recognized it when she touched her upper lip and found “an acne” on it. The patient wore complete dentures since age 17 and was not aware of any pain or tenderness in the area. Extra and intraoral examination revealed a mobile nodular lesion located in the right aspect of the upper lip near the nose and in the vestibular fornix between the lateral incisor and canine. Microscopic examination confirmed the final diagnosis of CA. The patient is currently free of disease 54 months after surgical excision of the tumor.

Local excision of symptomatic nodules seems to be sufficient to manage patients with multifocal CA.10 But, unlike other benign tumors, CA may need a longer follow-up due to its tendency towards multifocal occurrence and late recurrence.3,7

Effect of Cavosurface Margin Configuration of Class V Cavity Preparations on Microleakage of Composite Resin Restorations
Authors: Ghavamnasiri Marjaneh , Bagheri Mahshid
Published: July 2019

Aim

The aim of this study was to compare the marginal leakage of hybrid and microfilled composite resin in Class V restorations with and without an enamel bevel.

Methods and Materials

Fifty-six cavities were prepared on the buccal and lingual surfaces of 28 extracted human molars using a round bur with the dimensions of 3×2×1.5 mm. The specimens were divided into two groups of 28 based on the cavosurface margin configuration (beveled and non- beveled). Each group was then divided into two subgroups (n=14) based on the type of composite resin (microfilled and hybrid) used for restoration. After completing restorative procedure, specimens were thermocycled and immersed in 0.5% basic fuchsine. Samples were embedded in polyester and then sectioned both mesiodistally and buccolingually. Dye penetration was observed with a stereomicroscope at 25x magnification. Statistical nonparametric analysis Kruskal-Wallis and Mann-Whitney tests were performed to compare the data (a=0.05).

Results

There was no statistically significant difference between the two types of composites and two types of enamel margins with respect to microleakage (P>5%). The degree of microleakage at the gingival margin located in dentin of each group was more than that of the enamel margin (P<5%).

Conclusion

An enamel bevel in a Class V cavity preparation had no effect on the reduction of marginal leakage using either hybrid or microfilled composite resin.

In vitro Mechanical Testing of Glass Fiber-reinforced Composite Used as Dental Implants
Authors: Lassila Lippo , Vallittu Pekka , Ballo Ahmed , Nărhi Timo
Published: July 2019

Aim

The aim of this study was to evaluate the design of fiber-reinforced composite (FRC) on some mechanical properties of a dental implant.

Methods and Materials

FRC implants were fabricated using different polymerization conditions and designs of the glass-fiber structure. Specimens were tested with a cantilever bending test and a torsional test. The degree of monomer conversion (DC%) was measured using a Fourier transform infrared spectroscopy (FTIR).

Results

Statistical analysis showed significant differences between groups revealing mean fracture load values from 437 N to 1461 N. The mean torsional force in fracture varied from 0.01 to 1.66 Nm. The DC% varied from 50% to 90%.

Conclusion

This study suggests by modifying the polymerization conditions and fiber orientation of FRC implants, the biomechanical properties of an FRC can be tailored to the needs of dental implants.

SEM Analysis of the in situ Early Bacterial Colonization on Two Novel Feldspathic Ceramics Submitted to Different Types of Glazing
Authors: Bottino Marco Antonio , Valandro Luiz Felipe , Pereira Sarina Maciel Braga , Kantorski Karla Zanini , Brentel Aline Scalone
Published: July 2019

Aim

The aim of this study was to evaluate in situ, the early bacterial colonization on feldspar-ceramics submitted to different glazing.

Methods and Materials

Fourteen standardized disc specimens (diameter: 5 mm, thickness: 1.5 mm) of each of two micro-particulate feldspathic ceramics (VM7 and VM13, Vita) were produced according to manufacturers’ specifications for a total of 28 specimens (24 for the analysis of biofilm and 4 for topographic analysis analyzing the ceramic surfaces). Specimens from each type of ceramic were submitted to two different glazing methods composing four groups: VM7 glazed using glazing liquid Vita Akzent® 25 (G1) and glaze firing (G2), VM13 glazed using glazing liquid (G3) and glaze firing (G4). Six individuals (n=6) wore oral appliances with four ceramic specimens, fixed on the buccal face of the appliances. After 8 hours, each sample was evaluated for the presence (1) or absence (0) of bacterial colonization under a scanning electron microscope (SEM) on five randomly selected fields. The value for each sample was cumulative of the results observed in the fields. One sample from each group was evaluated under a SEM to verify the topographic pattern.

Results

There was no difference with regard to bacterial colonization between the feldspar-ceramics and between the glazing types (Kruskal-Wallis non-parametric test).

Conclusion

Feldspar-ceramics submitted to firing or glaze firing with Vita Akzent® 25 present a similar condition for in situ bacterial colonization. The similar topographic pattern of the ceramic surfaces seems to have influenced the bacterial colonization.

Aim

The aim of this study was to compare the bond strength of resin composites to dental structure photoactivated with a light emitting diode (LED) curing unit.

Methods and Materials

One hundred bovine incisors were selected and a conical cavity was prepared in the facial surface of each tooth. Clearfil SE Bond (Kuraray CO., LTD. Osaka, Japan) adhesive system was applied, and the cavities were filled with a single increment of Filtek™ Z250 (3M ESPE, St. Paul, MN, USA) or Esthet-X (Dentsply-Caulk – Mildford, DE, USA). The specimens were assigned to ten groups (n=10) according to the irradiance used: 100, 200, 300, 400, or 500 mW/cm2. Photoactivation was accomplished using an Ultrablue IS LED (DMC Equipamentos LTDA, São Carlos, SP, Brazil). The radiant exposure time was kept constant. A push-out test was conducted in a universal testing machine. Bond strength values were submitted to a two-way analysis of variance (ANOVA) and a Tukey's test at the 5% significance level.

Results

The bond strength of the Z250 was higher than the Eshet-X (p<0.05). However, the modulation of irradiance adjusted to the same radiant exposure had no influence on Z250. The bond strength using an irradiance of 100mW/cm2 was higher than the other levels for Esthet-X. When composites were compared, no significant differences were detected between them for activation with irradiances of 100 and 200 mW/cm2.

Conclusion

The modulation of the luminous energy emitted by LED was almost unable to provide significant differences among the groups for both composites, except for a lower irradiance of Esthet-X.

Treatment of Painful Post-traumatic Peripheral Neuropathy with Capsaicin in an Edentulous Patient with Extreme Resorption in the Mental Region: A Case Report
Authors: Pastre Therezinha , Faot Fernanda , Wastphalen Fernando H. , da Rosa Rosena Santos
Published: July 2019

Aim

The aim of this report is to present a clinical case of extensive alveolar resorption in the mental region of the mandible of a complete denture wearer for which capsaicin was used for alleviation and remission of posttraumatic painful peripheral neuropathy.

Background

Resorption of the residual ridge occurs in a chronic and progressive manner, altering the configuration of the ridge and the mucosa covering it and subsequently compromising the stability of the complete denture prosthesis. Individual variability associated with such factors as gender, age, edentulous period, nutrition, excessive load and compression on the ridge, parafunctional habits, occlusal instability, and maladaptation of the prosthesis may have a role in the rate and manner of bone loss.

Report

A 62-year-old woman, edentulous at the age of 30, presented with complaints of pain and spontaneous “electrical shocks” in the mucosa under her mandibular complete denture. The pain increased while chewing approximately two years ago due to the pressure of this denture on her supporting tissues. The patient indicated the level of pain corresponded to a score of ten out of ten on the Visual Analogical Scale (VAS). Treatment included denture replacement and topical application of capsaicin gel using a custom tray technique.

The review of the literature and the results obtained from the management of this case have served to emphasize how much neuropathic pain research has demonstrated the complexity of its neurophysiologic mechanism due to the lack of association with any somatic manifestation.

During the fabrication of a new lower denture the topical application of capsaicin was shown to be effective in the relief and remission of the painful symptoms of the neuropathy as of this writing.

Published: July 2019

Aim

This case report aims at describing an infection of the tongue as a manifestation of aTrichosporon asahiiinfection, its association with bronchial asthma and steroid administration, and to present a review of the literature pertaining to its antifungal susceptibility profile.

Background

Trichosporon asahiihas been reported to be associated with a wide spectrum of clinical manifestations, ranging from superficial infection to severe disseminated diseases, particularly in immunocompromised patients.

Case Report

A 36-year-old male asthmatic patient with recurrent glossitis presented with a chief complaint of burning sensation and two red areas on the dorsum of the tongue of three months duration. The glossitis was associated withTrichosporon asahii, which had a reduced susceptibility to some azole antifungal agents.

Trichosporon asahiiis an emerging fungal pathogen which may cause a wide range of clinical manifestations. More reports on its various clinical presentations in the oral environment need to be made available in the literature. To date there is a paucity of data on its prevalence, pathogenesis, and antifungal resistance mechanism.

Implementation of a Digital Radiographic Image Acquisition and Retrieval System (DRIARS) Using a Wireless Network in an Orthodontic Department
Authors: Mupparapu Muralidhar , Binder Robert E. , Cummins John M. , Feldman Cecile A. , Cappelli Mark A. , Matheson Pamela B.
Published: July 2019

Aim

The objective of this report is to describe the implementation and pilot-test of an integrated wireless local area network (WLAN) system that incorporated the Planmeca Promax® CCD based digital panoramic/ cephalometric x-ray system, Dolphin® software, and multiple remote user units to increase the efficiency of data management by the residents in the Department of Orthodontics.

Background

The Department of Orthodontics of the New Jersey Dental School (NJDS) acquired the Dolphin® cephalometric analysis software and the Planmeca Promax® digital panoramic/cephalometric x-ray units on separate occasions. Dolphin has been in use for many years at this institution, the current version being 10, and the Promax was acquired in the Fall of 2002. The digital panoramic and cephalometric radiographs were acquired and stored separately in the Planmeca's Dimaxis database.

Report

During the incorporation of the WLAN, there was an opportunity to research and install the best available security system for the WLAN so it could be a network model for the other departments within the dental school and perhaps other dental schools around the nation.

Digital radiographs, once obtained, can be stored locally or transmitted securely to remote locations via a local area network. This article describes the selection criteria and methodology that would optimize the transmission and retrieval of such images instantaneously on demand at chair side locations. This will not only save significant clinical time but will enhance the productivity of the clinic in the long run.

Composite Resin Microhardness: The Influence of Light Curing Method, Composite Shade, and Depth of Cure
Authors: Zanchi Cesar Henrique , Demarco Flávio Fernando , de Araújo Camila Silveira , Schein Marcelo Thomé , Rodrigues Sinval Adalberto
Published: July 2019

Aim

The aim of this study was to investigate the influence of light curing method, composite shade, and depth of cure on composite microhardness.

Methods and Materials

Forty-eight specimens with 4 mm of depth were prepared with a hybrid composite (Filtek Z-100, 3M ESPE); 24 with shade A1 and the remaining with shade C2. For each shade, two light curing units (LCUs) were used: a quartz-tungsten-halogen (QTH) LCU (Optilight Plus - Gnatus) and a light emitting diode (LED) LCU (LEC 470 II - MM Optics). The LED LCU was tested using two exposure times (LED 40 seconds and LED 60 seconds). After 24-hour storage, three indentations were made at mm depth intervals using a Knoop indenter. Data were submitted to three-way analysis of variance (ANOVA) and Tukey's test (p<0.05).

Results

The three factors tested (light curing method, shade, and depth) had a significant influence on the composite microhardness (p<0.05). All groups presented similar hardness values in the first mm, except for composite shade C2 cured with LED for 40 seconds. The hardness decreased with depth, especially for shade C2 for 40 seconds. Increasing light-curing time with LED produced hardness values similar to the QTH.

Conclusions

The light curing method including variations of time, the depth of cure, and the composite shade influence the composite microhardness.

Clinical Significance

Clinicians should avoid thicker increments when working with composite restorations. Extended light-curing time might be indicated depending on the composite shade and on the light-curing device.

Clinical and Radiological Findings Related to Tuberous Sclerosis Complex: A Case Report
Authors: Gupta Siddharth , Bhowate Rahul , Degwekar Shirish S.
Published: July 2019

Aim

The aim of this report is to present the intraoral and extraoral clinical features of a young female patient with tuberous sclerosis complex (TSC) who exhibited multiple hamartomas of various organ systems including a fibromatous growth on the gingiva.

Background

TSC is a rare neurocutaneous syndrome exhibiting multiple hamartomatous proliferations that may involve multiple organs such as the brain, kidney, heart, eyes, lungs and skin. Oral manifestations such as enamel pitting and fibromatous growth of the gingiva are commonly seen in patients with TSC.

Report

A 16-year-old female patient presented with a painless interdental gingival growth in the maxillary left incisor and canine region that bled occasionally. Associated findings were adenoma sebaceum (angiofibromas) on the face, a Shagreen patch on the lumbosacral region, ash leaf spots on the trunk, and subangual fibromas (Koenen's tumor) on the nails of fingers and toes. The final diagnosis of TSC was made on the basis of the clinical findings of the skin, computerized tomography (CT) findings of the brain and kidney, ultrasonographic findings of kidney, and a histopathologic evaluation of the gingival growth which met the major and minor criteria required for a diagnosis of TSC.

This case report is a good example of the complex nature of patients with TSC. The diagnosis and management of these patients varies depending on the specific presentation of the disease. Dentists need to be mindful of the systemic issues as well as oral conditions related to this disease. Dental practitioners are advised to work closely with the patient's physician during treatment.
