In forensic science, the information that teeth provide to the age estimation process isvery important. In adults, one of the most widely used indicators of skeletal age is theRoot Dentin Translucency (RDT), mainly through the Lamendin technique, which isused in various Latin American contexts. Recently, Parra et al. (2020) have developeda Bayesian regression model using the Lamendin technique to establish standardizedcriteria for estimating age-at-deathin adults in various forensic contexts. In this study,we evaluate the applicability of this proposal together with the proposal by Lamendinet al. (1992) and Prince and Ubelaker (2002) in Latin American contexts. A sample ofsingle-rootedteeth belonging to 805 individuals from six Latin American countrieswas used. The results of the three proposals considered were analyzed taking intoaccount factors such as age, sex, origin, and the tooth surface on which the variableswere surveyed. Of the factors that would affect the estimates, it was found that theage of the individuals had the greatest influence. However, it was confirmed that thesex and surface of the teeth on which the measurements were taken did not influencethe final result. On the other hand, as we expected, the application of the analyzedproposals would also be possible in other forensic contexts, as shown by the resultsobtained according to the origin. This research expands the FIDB with more informationon Latino contexts.
