“…This in agreement to some of the previous studies [2,5,11,17,20,21] while in contradiction to study by Solari et al [20] and Chandrmohan et al [15] who find significant differences in development in males and females (Table 5). symmetry in third molar development in both jaws.…”

“…Tooth or dentition being the hardest structure in the body survives every disaster such as fire accidents, bomb blast, plane crashes, mass disasters etc [7,8,10]. The multiple teeth in varied stage of dental development provide the sufficient data source for accurate age estimation, but only till the age of 14 years [2,11,12]. After the eruption of second permanent molar that is i. e. after 12-13 years of age the only teeth remain to develop is the third molar [13,14].…”

Objectives: The need for age estimation is increasing day by day; difficulty in human age estimation after 14 years of age has greatly shifted the focus on third molar. Radiographic evaluation of presence, position and degree of third molar formation can be utilized in forensic age estimation. The present study aimed to evaluate the development of third molar in relation to chronological age. Methods:The present study included sample of 479 subjects in the age range 5-30 years, for each subject, orthopantomograph was taken. To assess the developmental stages of third molars; the staging system described by Nolla [1] CM was used.Results: Overall, no significant differences were observed in mean ages at which the developmental stages were reached in all four third molars. The absence of crypt was observed more for maxillary third molars, contrarily, stages 1, 2, 3 were reached earlier in mandibular third molars. In case of presence of four completely developed third molars in a subject, the probability of an individual to be older than 18 years of age was 94.35% for females and 95.23% for males. Conclusion:Third molar teeth are well known for their variability in development, eruption pattern, size, contour and relative positions as compare to other teeth. In spite of variations, third molars are still at the centre of medicolegal interest; and its significance in age determination is justified as no other reliable age indicator is available to determine the age in adults. Besides, it will help to separate adolescents from adults as jurisprudence differs for juvenile detainees.

“…The average age at which enamel formation is completed for each specific tooth has been determined previously and is dependent on the tooth number and gender of the person (3,4,10,11). If the sex of a person is unknown, the average time for enamel completion for males and females is calculated.…”

“…The date of formation of a tissue can be estimated from the bomb curve by considering these lags in incorporation and relating the 14 C concentration with the date. Enamel formation can occur over several years in humans (10,11). For radiocarbon analysis of tooth age, the upper limit of enamel formation has been used (i.e.…”

Age determination of unknown human bodies is important in the setting of a crime investigation or a mass disaster because the age at death, birth date, and year of death as well as gender can guide investigators to the correct identity among a large number of possible matches. Traditional morphological methods used by anthropologists to determine age are often imprecise, whereas chemical analysis of tooth dentin, such as aspartic acid racemization, has shown reproducible and more precise results. In this study, we analyzed teeth from Swedish individuals using both aspartic acid racemization and radiocarbon methodologies. The rationale behind using radiocarbon analysis is that aboveground testing of nuclear weapons during the cold war (1955-1963) caused an extreme increase in global levels of carbon-14 ( 14 C), which has been carefully recorded over time. Forty-four teeth from 41 individuals were analyzed using aspartic acid racemization analysis of tooth crown dentin or radiocarbon analysis of enamel, and 10 of these were split and subjected to both radiocarbon and racemization analysis. Combined analysis showed that the two methods correlated well (R 2 ‫؍‬ 0.66, p < 0.05). Radiocarbon analysis showed an excellent precision with an overall absolute error of 1.0 ؎ 0.6 years. Aspartic acid racemization also showed a good precision with an overall absolute error of 5.4 ؎ 4.2 years. Whereas radiocarbon analysis gives an estimated year of birth, racemization analysis indicates the chronological age of the individual at the time of death. We show how these methods in combination can also assist in the estimation of date of death of an unidentified victim. This strategy can be of significant assistance in forensic casework involving dead victim identification. Molecular & Cellular Proteomics 9:1022-1030, 2010.
