In forensic science, the information that teeth provide to the age estimation process is very important. In adults, one of the most widely used indicators of skeletal age is the Root Dentin Translucency (RDT), mainly through the Lamendin technique, which is used in various Latin American contexts. Recently, Parra et al. (2020) have developed a Bayesian regression model using the Lamendin technique to establish standardized criteria for estimating age-at-death in adults in various forensic contexts. In this study, we evaluate the applicability of this proposal together with the proposal by Lamendin et al. (1992) and Prince and Ubelaker (2002) in Latin American contexts. A sample of single-rooted teeth belonging to 805 individuals from six Latin American countries was used. The results of the three proposals considered were analyzed taking into account factors such as age, sex, origin, and the tooth surface on which the variables were surveyed. Of the factors that would affect the estimates, it was found that the age of the individuals had the greatest influence. However, it was confirmed that the sex and surface of the teeth on which the measurements were taken did not influence the final result. On the other hand, as we expected, the application of the analyzed proposals would also be possible in other forensic contexts, as shown by the results obtained according to the origin. This research expands the FIDB with more information on Latino contexts.
International forensic protocols are typically developed by committees drawn from multiple disciplines and are presented to the forensic community in the hope the protocols will be adopted. While the contributors are undoubtedly experts within their respective disciplines, they may lack practical international large-scale death investigative experience. As a result, the protocols produced are often cumbersome or impractical. Many are abandoned or heavily modified after brief field trials, such as the INFORCE mass grave field protocol in Iraq in 2004 or the Simmon's personal identification protocol in Kosovo in 2000. Information gleaned from any brief field trials is rarely conveyed to the larger forensic community. This study presents the findings of a pilot study examining the validity and feasibility of a proposed protocol, the International Protocol on the Documentation and Investigation of Sexual Violence in Conflict:
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
