Evaluación del conocimiento de los cirujanos dentistas brasileños sobre aspectos bioéticos en el tratamiento odontológico

Professional-patient relationship and its importance for a good performance and success of the dental treatment must be reflected upon by means of their bioethical aspects. Our study aimed at evaluating dentist-surgeons' knowledge (n=163) in conducting specialization courses at São Paulo State University-UNESP, on these aspects. Out of the people surveyed, 88.1% mentioned that a decision for the treatment should be made by mutual agreement between professionals and patients, however, 26.4% report that patients' or their legal representative's participation in decision-making can cause negative interference. Professionals' acting when patients choose a less suitable treatment, 95.6% try to convince patients that it is not the best choice and persuade them for a better one by keeping the paternalistic model. It was noticed that 20.3% did not know how to relate the importance of professional-patient interaction as regards the dental treatment. It was therefore concluded that many dentist-surgeons are not taking these bioethical aspects into account in clinical practice.

Concurrence between the maxillary midline and bisector to the interpupillary line

Purpose: Symmetry is one of the factors that contributes to facial harmony, and in oral rehabilitation it determines the success of esthetic treatment. Therefore, the aim of the present study was to analyze the axial symmetry between the bipupillar midline and maxillary central incisors midline of 102 dental students (both genders) distributed across five Brazilian dental schools. Materials and Methods: Students with no teeth missing and who had never been subjected to any dental treatment were selected. Photographs were taken with a Dental Eye III camera with a 100-mm macro objective and ratio of 1 : 10 from natural size, recorded on an Ektachrome ASA/ISO 100 film. The images were developed and applied to Microsoft Office Power Point 2007 software. The results were analyzed by analysis of variance and Student's t-test (= 0.05). Results: There was no significant correlation between bipupillar midline and the maxillary dental midline, irrespective of gender. Conclusion: No significant coincidence was observed between the interpupillary and dental midline. However, the interpupillar distance and its relationship with other anatomic structures may be used as a reference in treatment, but measurements must be assessed individually. CLINICAL SIGNIFICANCE Anatomic measurements and facial proportions can be helpful during the planning of esthetic oral rehabilitation. © 2009 Wiley Periodicals, Inc.

Incontinentia pigmenti presenting as hypodontia in a 3-year-old girl: A case report

Introduction. Incontinentia pigmenti or Bloch-Sulzberger syndrome is a rare X-linked dominant disease that mainly affects the skin, eyes, hair, central nervous system and teeth. The disease is predominant among women. Although dermatologic manifestations are among the most important aspects for the diagnosis of the syndrome, they are less damaging to the patient and do not require treatment. However, oral involvement characterized by hypodontia of deciduous and permanent teeth is important for the diagnosis and treatment of the patient. Case presentation. We report the case of a 3-year-old girl with ophthalmologic and neurologic disturbances, cutaneous manifestations and hypodontia. Since the patient did not present more damaging manifestations such as neurologic and/or ophthalmologic problems, her most severe complications were related to dental anomalies. The importance of integrated dental treatment, which combines pediatric dentistry, orthodontics and conventional prosthesis, is emphasized. Conclusion. Hypodontia is a frequent finding in incontinentia pigmenti, and dentists should be aware of this condition in order to help with the diagnosis. © 2009 Kitakawa et al; licensee BioMed Central Ltd.

Genetic polymorphism of Streptococcus mutans strains associated with incomplete caries removal

Aim: Despite the antibacterial properties of dental materials, the survival of residual bacteria under restorations has been demonstrated after incomplete caries removal. The aim of this study was to evaluate the genetic polymorphism of Streptococcus mutans strains isolated from deep dentinal lesions before and three months after incomplete caries removal. Methods: Samples of carious dentin were collected from 33 primary and/or permanent molars before and after indirect pulp treatment and processed for microbiological isolation of mutans streptococci (MS). After three months of the dental treatment, positive cultures for MS were detected in only ten of these teeth. DNA of MS isolates were obtained and subjected to polymerase chain reaction (PCR) for identification of S mutans. The arbitrary primed-PCR method (primer OPA-13) was used to detect the genetic polymorphism of S. mutans strains. Results: Identical or highly related S. mutans genotypes were observed in each tooth, regardless of the collect. Considering each tooth separately, a maximum of nine genotypic patterns were found in each tooth from all the collects. In addition, at least one genotypic pattern was repeated in the three collects. Genetic diversity was observed among the S. mutans isolates, obtained from different teeth after three months of the dental treatment. Conclusions: The persistence of identical genotypic patterns and the genetic similarity among the isolates, from the same tooth in distinct collects, showed the resistance of some S. mutans strains after incomplete caries removal treatment.

Escala de ansiedade odontológica: Reprodutibilidade das respostas dadas em entrevistas telefônicas e pessoais

Objective: To estimate the intra-examiner reproducibility of the Dental Anxiety Scale (DAS) when applied by phone and personal interviews and to evaluate the association between the level of anxiety and the factors of interest. Method: The participants were 50 individuals (n=38 females) with mean age of 23.9±8.9 years, living in the city of Araraquara, SP, Brazil. The volunteers answered the DAS by means of two phone interviews with one-week interval between them. After 30 days, the DAS was applied to the same participants by means of personal interviews at two moments with one-week interval between them. Intra-examiner reproducibility was determined using Kappa (K) statistics by point and by confidence interval. Results: The intra-examiner agreement for the level of anxiety was 0.82 (0.75-0.90) for the phone interview and 0.69 (0.60-0.79) for the personal interview. Two of the DAS questions presented statistically significant difference in the intra-examiner reproducibility, with better agreement for the answers given by the participants during phone calls. The prevalence of dental anxiety in the sample was 92.0%, in such a way that 70.0%, 18.0% and 4.0% of them presented low, moderate and exacerbated anxiety. Conclusion: The classification of the individuals according to the anxiety level performed by means of phone and personal interviews presented statistically similar agreement. However, there was better agreement with phone calls for the questions referring to anxiety in the dental office's waiting room and during preparation of the motor for use in the dental treatment.
