Effectiveness of different methods for the detection of binge drinking in dentistry students

The purpose of this study was to estimate the alcoholic beverage consumption among undergraduate students of a Dentistry Course and compare the effectiveness of screening methods for the detection of binge drinking. A total of 284 undergraduate students participated in the research. We used the full AUDIT and their reduced forms (AUDIT-3 and AUDIT-C). In addition, a ROC curve was created and its area was calculated. Of the students, 91.0% and 90.6% of the male and female genders, respectively, reported alcohol beverage consumption. Bing-drinking behavior occurred in 69.2% of the men and in 52.4% of the women. The 3 methods showed good discriminatory ability. For the women, there was a significant difference between the AUDIT-3 and AUDIT-C. Both the complete version of AUDIT and its reduced forms presented good discriminatory ability

Dentistry teachers and the burnout syndrome

The Burnout Syndrome is considered a psychosocial problem to which teachers are routinely exposed. This study was conducted to estimate the prevalence of burnout in Dentistry teachers and its relation to relevant socio-demographic variables. The participants were 70 teachers from the undergraduate Dentistry Course, Faculty of Dentistry of Araraquara – UNESP. Oldenburg Burnout Inventory (OLBI) was used. The prevalence of burnout was estimated. In order to compare performed. Mean age of participants was 46.0 ± 6.1 and teaching experience was 19.6±7.6 years. The prevalence of burnout was 17.1%. Low mean scores for Exhaustion (2.11±0.61) and Disengagement (1.73±0.50) were observed. There reported taking medication due to work (p=0.008) and for those who have thought about quit teaching (p=0.001). There scores according to the habit of taking medication, the experience as a teacher and gender

Laboratory testes with quality data in Dentistry

In laboratory tests, just following the manufacturer’s instructions of materials or equipments may not be enough to obtain reliable data. Thus, intra and inter-examiners studies may be required. The aim of this study was to illustrate the application of the Intraclass Correlation Coefficient (r) in a study related to the color changing and hardness of composite resin conducted by two examiners. The color and hardness of 10 specimens of composite resin were evaluated by a colorimetric spectrophotometer and hardness tester, respectively, at two different times. Two trained examiners performed two measurements with an interval of one week. Specimens were stored in artificial saliva at 37±1ºC for 7 days. The Intraclass Correlation was used for analysis of intra and inter-examiner reproducibility. The intra-examiner reproducibility was 0.79, 0.44 and 0.76 for L, a and b color coordinates for the examiner 1 and 0.84, 0.23, 0.21 for examiner 2. For hardness, r-values were 0.00 and 0.23 for the examiner 1 and 2, respectively, showing unsatisfactory agreement on color and hardness evaluation for both examiners. It was noted that only the observation of protocol for use of equipment and examiners training were not sufficient to collect reliable information. Thus, adjustments in the experimental protocol were made and devices were produced to standardize the measurements. The reproducibility study was performed again. For examiner 1, values as 0.90, 0.59 and 0.79 were verified for L, a and b coordinates and, for examiner 2 were obtained values of 0.90, 0.75, 0.95. In relation to hardness, r-values of 0.75 and 0.71 were obtained for examiners 1 and 2, respectively. The inter-examiner reproducibility was 0.86, 0.87, 0.91 for L, a and b coordinates and 0.79 for hardness. It was concluded that intra and inter-examiner calibration is essential for obtaining quality measurements in laboratory tests.

Visualisation and reconstruction in dentistry

Visualisation in the field of dentistry has nor, thus far, reached the same development as other medical fields. Potential applications of visualisation techniques in this area, however, are many, ranging from educational displays to training for delicate procedures. This paper reports on the investigation of techniques for handling three-dimensional models of teeth, aiming at investigation of dental structures. An algorithm was implemented for this purpose, which reconstructs three-dimensional teeth models from two-dimensional contour slices. Results employing various data sets are presented, including the output of VRML models for exploration.

Management of accidental swallowing in implant dentistry

This report describes a protocol for managing the accidental swallowing of dental instruments in implant dentistry, illustrated by a patient who accidentally swallowed a hexagonal wrench. The first step was to refer the patient to the medical emergency hospital service for radiographic and clinical evaluation. The hexagonal wrench was located in the stomach and was immediately removed with an endoscopic procedure. The gastric mucosa was sampled via biopsy and the sample submitted to the urease test, which was positive for Helicobacter pylori. Triple treatment was instituted for gastritis caused by H pylori to avoid exposing the patient to unnecessary risk. Removal of a foreign body by means of an endoscopic procedure constitutes a safe and effective treatment.

Sexual haressement in dentistry: prevalence in dental school

OBJECTIVE: Sexual harassment is unlawful in all work and educational environments in most nations of the world. The goals of this study were to describe the sexual harassment prevalence and to evaluate the experiences and attitudes of undergraduate students in one dental school in Brazil. MATERIAL AND METHODS: An 18-item questionnaire was administered to 254 dental students with a completion rate of 82% (208). Students were requested to respond to questions about their background and academic level in dental school, their personal experiences with sexual harassment and their observation of someone else being sexually harassed. Bivariate statistical analyses were performed. RESULTS: Fifteen percent of the students reported being sexually harassed by a patient, by a relative of a patient or by a professor. Male students had 3 times higher probability of being sexually harassed than female student [OR=2.910 (1.113-7.611)]. Additionally, 25.4% of the students reported witnessing sexual harassment at the school environment. The majority of students did not feel professionally prepared to respond to unwanted sexual behaviors. CONCLUSION: These findings demonstrate that sexual harassment can occur in a dental school setting. There is a need for ongoing sexual harassment education programs for students and university staff. Increased knowledge of sexual harassment during graduation can better prepare dental professionals to respond to sexual harassment during their practice.

Brazilian dentistry profiles and workforce

The aim of this study was to assess the dentistry profile, based on social and demographic data, post-graduation formation, and to verify the insertion of dental graduates in the labour force. The participants were professionals graduated from a Brazilian Public Dental School, between 2000 and 2010. An instrument was sent by mail and/or e-mail to them. It was used Kruskal Wallis Test. Among 1047 questionnaires, 189 returned and 65.6% were answered by female. In relation to post-graduation course, 57.7% of professionals performed it, however 56.9% not attended only in their area; 66.6% of professionals are concentrated in cities larger than 100 thousand habitants. There was association between income and gender, and others. The predominant work modality was self-employed. Among the total, 36.5% want to work part-time in dentistry. The female gender was predominant and there was wage discrepancy between genders. The professionals have been concentrated in largest cities.

Qualitative methodogy: revealing a new path for research in dentistry

Currently, it is easy to find health professionals who not only attach importance to qualitative methods, but also recognize their help to better understand their patients' lives. However, its use in dentistry is still incipient, either due to ignorance or because of technical / operational difficulties in identifying possibilities for their use in research. Thus, the purpose of this study was to review the literature on the characteristics and peculiarities of the qualitative methodology, demonstrating their techniques of collecting, recording and analyzing data. For this, we performed a descriptive literature, from a survey in the "LILACS", "BBO" and "PUBMED" databases, by keywords related to the theme, selecting only the papers that mentioned the "importance" of qualitative research, the "characteristics and fundamentals," and the "techniques of collecting, recording and data analysis" involving this methodology. It was found that all studies have highlighted the importance of qualitative research to the construction of new knowledge that cannot be achieved by quantitative data. We found many different techniques to gather, record and analyze qualitative data applied to the dentistry field. It was concluded that qualitative research represents a new path to be followed by dentistry, so that we are able to plan actions in ethical and humane public health dentistry, bringing better results to the population, because of the depth of knowledge that your date can.
