Evolution of forensic odontology: An overview

Awareness of Forensic Odontology among Dental Students and Faculty in Cyprus: A Survey-Based Study

This study aimed to evaluate the awareness, comprehension, and practices concerning forensic odontology among dental students and faculty at a Dental School in Cyprus. An online, cross-sectional, descriptive survey, employing an adapted, self-administered questionnaire, was disseminated to all dental students and faculty at the School of Dentistry, European University Cyprus, in November 2022. The survey assessed participants' demographic information and explored their awareness with questions alluding to knowledge, attitudes and practices in forensic dentistry. Of those surveyed, 47 faculty members and 304 students responded, yielding response rates of 66.2% and 80%, respectively. Statistical analysis, including Kendall's tau test and χ2 test were employed to examine correlations and associations, with Cramer's V used to measure the strength of significant associations. The predetermined significance level was α = 0.05. Awareness levels were assessed through participants' responses to specific questions in the survey. It was revealed that 87% of faculty and 65% of students were familiar with forensic odontology. A noteworthy 94% of faculty and 85% of students recognized teeth as DNA repositories. A high percentage, 98% of faculty and 89% of students, acknowledged the role of forensic odontology in the identification of criminals and deceased individuals. Awareness of age estimation through dental eruption patterns was evident in 85% of faculty and 81.6% of students. A substantial proportion (80% of faculty) maintained dental records, while 78% of students recognized the importance of dental record-keeping in ensuring quality care. Interestingly, 57% of students and 64% of faculty were aware of the possibility of dentists testifying as expert witnesses. The majority, 95.7% of faculty and 85% of students, concurred that physical harm, scars, and behavioral alterations predominantly indicate child abuse. The findings, revealing robust awareness among respondents, underscore the importance of enhancing faculty engagement in relevant seminars to further strengthen their knowledge. Additionally, emphasizing improved record-keeping practices for potential forensic applications emerges as a crucial aspect. These insights have implications for refining dental education in Cyprus and enhancing forensic practices by promoting ongoing professional development and emphasizing meticulous record-keeping within the dental community.

Dental Radiographic/Digital Radiography Technology along with Biological Agents in Human Identification

The heavy casualties associated with mass disasters necessitate substantial resources to be managed. The unexpectedly violent nature of such occurrences usually remains a problematic amount of victims that urgently require to be identified by a reliable and economical method. Conventional identification methods are inefficient in many cases such as plane crashes and fire accidents that have damaged the macrobiometric features such as fingerprints or faces. An appropriate recognition method for such cases should use features more resistant to destruction. Forensic dentistry provides the most appropriate available method for the successful identification of victims using careful techniques and precise data interpretation. Since bones and teeth are the most persistent parts of the demolished bodies in sudden mass disasters, scanning and radiographs are unrepeatable parts of forensic dentistry. Forensic dentistry as a scientific method of human remain identification has been considerably referred to be efficient in disasters. Forensic dentistry can be used for either "sex and age estimation," "Medical biotechnology techniques," or "identification with dental records," etc. The present review is aimed at discussing the development and implementation of forensic dentistry methods for human identification. For this object, the literature from the last decade has been searched for the innovations in forensic dentistry for human identification based on the PubMed database.

Analysis of 100 most cited articles on forensic odontology

OBJECTIVES

Bibliometric analysis of best-cited papers brings awareness about the influential publications and trends in the literature on a particular topic. This will help not only the researchers and academicians but also the students for selecting quality landmark articles. With this view in mind a bibliometric analysis was performed to identify the 100 top-cited papers on Forensic Odontology (FO) in the literature.

MATERIALS AND METHODS

A search was performed using Scopus database in August 2019. The articles were further reviewed and basic standard information related to bibliometric analysis was recorded.

RESULTS

The 100 most cited articles were published from 1985 to 2014 (77% published after 2001). The most frequently cited article received 259 citations, whereas the least received 31 (mean citations 58.78 ± 33.14). There were 16 different journals with Forensic Science International having the most number of articles (n = 36). One author had 16 articles while 8 authors had 4 or more articles published in the top 100 list. Belgium was the country with most number of articles (n = 17) followed by United States (n = 16). In terms of document type, 87 were original research, 7 conference papers and 6 reviews. Five organizations funded 5 of the top 100 articles. Katholieke Universiteit Leuven, Belgium affiliated the most documents (n = 16). Majority of the papers were related to age estimation (46) followed by victim identification (30), mass disaster (9), bite mark analysis (8), sex determination (5), race determination (4), dental DNA analysis (3), palatal rugae pattern (2) and lip prints (1).

CONCLUSION

This is first of its kind citation analysis of the 100 most cited articles in the field of FO. The results of this paper will help the researchers, academicians and students for appropriate article referrals.

Public awareness of forensic odontology and willingness to enroll in a prospective dental registry: A survey conducted in Saudi Arabia

Background

The establishment of a national dental registry provides a great opportunity for the healthcare and criminal investigation systems. Its feasibility would rely mainly upon public knowledge and a willingness to contribute dental profiles. The aim of this study was to evaluate the level of awareness among the Saudi public of forensic odontology and to evaluate their willingness to participate in a prospective national dental registry.

Methods

A cross-sectional survey based on a self-administered survey questionnaire was conducted in 2018 at the Al-Janadriyah National Festival in Riyadh, Saudi Arabia. Visitors were questioned about their demographic data and responded to 20 knowledge statements using the alternatives “correct”, “incorrect”, or “don’t know”. Their perception towards registries was assessed using 15 statements and a 5-point Likert scale. The percentage mean score (PMS) of knowledge, the mean positive response rate (MPRR) of participant perception, and their willingness to participate in a prospective dental registry were assessed with respect to their demographic characteristics.

Results

Complete surveys were received from 812 study participants (85.5% response rate). The PMS ± standard deviation of knowledge was 39.8 ± 22.5 and the MPRR of perception was 64.7 ± 25.5. More than two-thirds of the responders (n = 548, 67.5%) indicated a willingness to register in a future national dental registry. Differences in knowledge were identified with regard to sex, marital status, education, and occupation, while differences in perception and willingness to enroll were influenced by sex. After adjustment for possible confounders, female participants and employed participants were 1.7 times (95% confidence interval [CI] = 1.2–2.4) and 1.6 times [95% CI = 1.1–2.5] more likely to enroll in the proposed registry (P = 0.004 and P = 0.03, respectively). Higher knowledge and perception scores were associated with more willingness to enroll in the national dental registry (adjusted [adj.] P = 0.03 and adj. P < 0.001, respectively).

Conclusions

A future national dental registry in Saudi Arabia is expected to be well-received by the public. An improvement in the public’s knowledge regarding the importance of forensic dentistry is expected to encourage their active enrollment in such a registry. Although women and employed participants were more willing to enroll, it is too early to predict the rates of participation, given the fact that nationwide marketing surveys have yet to be launched.

Role of forensic odontology in the Indian Armed Forces: An unexplored arena

Forensic odontology (FO) is a branch of forensic medicine that in the interest of justice deals with proper handling and examination of dental evidence. Teeth can survive in most conditions encountered at death and during decomposition, even when the body is exposed to extreme forces and/or temperatures. FO is being practiced worldwide since 1775, after which it has not only become an integral part of the judicial system of the developed countries but also been adopted by the armed forces and investigative agencies of these countries. In India, the awareness of FO is gaining pace since the last decade after the establishment of various organizations and the Dental Council of India making it a part of the curriculum. However, its identity as an individual endeavour is still to be established. Awareness and applicability of FO in the Indian Defense Forces would be of great help for better and accurate record keeping of the dedicated and vigilant warriors of our army. These records will be of great help for easy recognition of our army men at the time of calamities, wars, and other difficulties. It would also be useful in the identification of terrorists who enter our country and travel easily in disguise.
