Thermal modifications of root transparency and implications for aging: a pilot study

An evaluation of dental methods by Lamendin and Prince and Ubelaker for estimation of adult age in a sample of modern Greeks

Teeth can be used as accurate tools in age-at-death estimation in forensic cases. No previous data exist on estimating age from teeth in a modern Greek population. The aim of this study was to evaluate Lamendin's and Prince and Ubelaker's ageing methods on a modern Greek skeletal sample. In total, 1436 single-rooted teeth from 306 adult individuals (161 males and 145 females) were examined. Only measurements of periodontosis and translucency showed positive correlation with age. Results showed a bias - an overestimation for ages under 40 years and an underestimation over this age. However, the use of wider age groups proved to be more appropriate. Low values of error were observed for the group of middle-aged individuals. In conclusion, both methods can be considered accurate in estimating age-at-death of middle-aged individuals. This study provides more information about the accuracy and applicability of these dental methods on modern European populations.

Technical note: The two step procedure (TSP) for the determination of age at death of adult human remains in forensic cases

This paper presents the principles and results of TSP (the two step procedure), a comprehensive (combined) method of age estimation in mature human skeletal remains. The first step consists of the examination of the pubic symphysis using the Suchey-Brooks system for a "pre-choice". Then for SBS phases I, II, III, (young adults up to about 40) the age estimate is given using the chronological interval corresponding to each phase. For SBS phase is IV, V or VI (mature adults, about 40 to 60), then (second step) the dental method of Lamendin (using single rooted tooth) will be applied alone. Both methods are fast, easy to learn and to use (requiring no preparation except cleaning soft tissues from the pubic bone) and are not expensive, making TSP usable by all pathologists or anthropologists in any Forensic unit. It is also of great practical use in mass disaster and mass grave situation. After 15 years of use, a literature review and four evaluation studies we confirm that TSP is more accurate than any single method for aging adults and at least as good as more complicated combined methods. Despite its advantages TSP is, like all other aging methods, not efficient in adults over 65 years of age.
