In 1992, Lamendin and colleagues introduced a novel procedure for estimating age-at-death using root dentin translucency as the main estimation variable. Its applicability has been positively verified in various populations of the world, although with certain limitations.In 2020, Parra and colleagues used the Lamendin technique and modified the original method by constructing a Bayesian algorithm. They developed a Database that they called Forensic International Dental Database (FIDB), which was implemented with 693 observations from the USA, Peru, Colombia and Spain. Garizoain and colleagues recently expanded the FIDB to 1,793 observations from different Latin American countries such as Argentina, Ecuador, Guatemala, Mexico, Peru, and Colombia.The authors have reported that the FIDB contributes to understanding the behavior of Root Dentin Translucency (RDT) and Periodontal Retraction (RP) as physiological indicators for estimating age, knowing the margins of error in the estimates and strengthening the statistical calculations implemented. So far the authors have suggested that the combination of RDT and PR represents a useful, simple and positively applicable method for any population in the world.
