Forensic Medicine and Anatomy Research (FMAR) , 2013, DOI: 10.4236/fmar.2013.13011
Abstract: This study proposed to evaluate the precision of Nicodemo, Moraes and Médici method and the method proposed by Demirjian and compare both methodologies in relation to the efficiency and applicability in the Brazilian population. The sample consisted of 124 panoramic radiographs of subjects in the age group from 7 to 16 years old, 66 patients female and 58 male. For the comparison of the genders in relation to the average percentage difference, the t-Student test was considered. In average the method of Nicodemo, Moraes and Médici presented for the female gender an estimated result 14.7% lower than the real age. For the male gender the estimative obtained was that for each year of variation of the real age the method of Nicodemo estimates a variation of 0.48 years, with a confidence interval of 95% given by (0.43; 0.54). For the method of Demirjian the result was that for each year of variation of the real age the method of Demirjian estimates a variation of 1.00 year, with a confidence interval of 95% given by (0.85; 1.15) for the male gender and 0.96 years, with a confidence interval of 95% given by (0.84; 1.08) for the female gender. It is concluded that the Method of Nicodemo, Moraes and Médici tends to underestimate the real age and that as the real age increases this underestimate becomes higher. Now, the method of Demirjian tends to over- estimate the real age in 8.2 months for the male gender and in 7.1 for the female one in average.

Introduction to Forensic Dentistry Continuing Education Course  [PDF]
Diane Osborne
Forensic Medicine and Anatomy Research (FMAR) , 2013,
Abstract: This course is an introduction to the basics of forensic dentistry beginning with its historical origins to modern advancements. After an introduction to basic principles, application of this information will be demonstrated in current cases, training in mass fatalities and participation in a mass fatality workshop scenario using dry skull remains. Time permitting, a tour of the Las Vegas Coroner’s Office will be available.

Microscopy Research (MR) , 2015, DOI: 10.4236/mr.2015.31001
Objectives: To evaluate quantitatively deformation of the angle of the horizontal plane of the bevel tip in new dental needles and in dental needles used in clinical procedures. Material and Methods: A cross-sectional study was performed with 360 dental needles from four different manufacturers. The needles were divided into four groups (90 per group): Group 1, Monoject\"\"; Group 2, DLP\"\"; Group 3, Badiject, and Group 4, Zeyco. The new and used needles were evaluated by scanning electron microscopy to evaluate quantitatively the deformation on the bevel. Results: All groups showed a significantly statistical difference between new needles and needles used for one or two injections (P < 0.05), except for those of Group 4, which exhibited no statistical difference. Conclusion: All dental needles used demonstrated tip deformation after their use, but in addition, dental needles without clinical use also showed deformation.

Health (Health) , 2015, DOI: 10.4236/health.2015.710141
Abstract: Objectives: To compare the empathy of students in two faculties of Dentistry in Peru and Argentina, three factors were considered: universities, academic year and gender. Material and Methods: Empathy matrices in Dentistry students were measured using the Jefferson Scale of Empathy, culturally validated in Peru and Argentina. Empathy data were compared among and within the faculties tested using a three-factor analysis of variance (model III), a Duncan test, and a discriminant analysis. The level of significance used was less than 0.05. Results: We found that differences existed between the students tested. The comparison between the levels of empathy in the studied factors and the presence of unexplained variance showed that empathy was able to differentiate populations. Conclusions: The results indicate variability in the empathy values associated with the factors studied. The discriminant test confirms the differences between faculties revealed by the data matrix resulting from the JSE. These differences are possibly due to the effect of educational and social factors.

Abstract: Background: The idea of establishing a Dental school at the Kwame Nkrumah University of Science and Technology (KNUST) was borne out of a need. There was a shortfall in the supply of dental surgeons, especially in the northern half of the country. Aim/Objective: To seek for feedback from KNUST Dental school graduates over the past six about their overall assessment of the BDS courses taught during their clinical training and challenges faced in the course of their training. Methodology: A cross-sectional retrospective study of all KNUST Dental school graduates from 2012 to 2017. A structured goggle form questionnaire was developed. The Google form link was emailed to the representatives who in turn forwarded the link to their year mates. The questionnaire was filled online and submitted as requested. Results: This represented 63.0% of the entire graduates from KNUST Dental School. The male to female ratio was 1.3:1.0. The age range of our graduate was from 24 yrs (3.8%) to 32 years (1.9%). The average age was 26.3 years. 48.10% of respondents said their training was very good. The major challenges were inadequate clinical space (25.2%) and lack of materials and dental chairs for students’ clinic (27.3%). Conclusion: On the whole, the quality of the training was rated as very good even though some of the courses taught during the clinical training were rated as poor. Inadequate dental chairs, laboratory and clinic materials, supervision of student’s clinic were some of the major challenges expressed by the graduates.
Epispemología para los Odontólogos
Galarraga Rodríguez,Nelly R;
Acta Odontológica Venezolana , 2004,
Abstract: the study of the epistemology, provides us the foundations on which operate the theories and the investigation; as professionals of the health we are usually inclined toward analytic procedures, looking for causal connections, but the conception of the nature of knowledge is much wider and our look can arrive as far as the horizon, for this reason we present this theoric and descriptive study, especially to dentists with the purpose of motivate them to read and to improbé their knowledge, on a topic that we estimate is important and useful, when thinking about an investigation or simply to carry out a reading.

Abstract: a descriptive study to 49 second-year dentistry students during the academic course 2002 - 2003 was carried out at the medical school in camagüey to evaluate the methods of characterization in the affective-motivational sphere, and the students' personal qualities with intervention of the group in the educational projection. the results of individual and group work were also determined. the techniques applied were created by adviser professors to determine the values and the individual and collective characteristics of the group of students as part of the educational work. the techniques consisted of painting a hand in which values were pointed out by the students in order of priority. in the center of the hand they expressed their adviser professor's predominant value. the students were told to draw a face where they reflected what they thought, heard, saw and spoke that was pleasant or not. to determine the individual acceptance in the group, they were given a list with the names of all students so that they classified them from the 1 to the 6 according to the individual approach to each one. after the techniques were applied in their initial phase, the intervention strategy that was part of the students educational project was carried out, so the activities could contribute to solve individual and group problems detected by the professor. the values students prioritized were dignity, solidarity and responsibility, increasing in the final evaluation collectivistic values. the adviser professors' values were responsibility, laboriousness in both surveys, humanism was predominant at the beginning and solidarity in the final survey. the presence of rejected and isolated students was determined by the group, decreasing this group of students in number after applying the strategy to incorporate those students to the group. the techniques used for the characterization reflected the students characteristics, their qualities and defects, as well as the changes experienced

Abstract: This personal reflection was written following the student protests which took place during the first semester of 2016 at the University of Talca, where like other universities in the country, the symptoms of an increasingly serious problem are being felt on a daily basis. Many students are experiencing a similar situation, as education in Chile is in a state of crisis, and dentistry is no exception.
