“…Research indicates that dental development is under greater genetic control and less susceptible to environmental influences (Cunha et al 2009, Franklin 2010, Saunders 2000. In addition, dental tissues are highly mineralized and thus more resistant to postmortem alterations (De Luca et al 2010, Meinl et al 2008.…”

The aim of this study was to test the accuracy of two methods for age estimation in non-adults, Cameriere's European formula and AlQahtani's London Atlas, on a multiethnic American sample. Radiographs of European, Hispanic and American Indian children (166 girls and 194 boys) aged between 6 and 17 years were analyzed following both methods. The accuracy of each method was assessed using the mean difference and the mean of the absolute values of the residuals (mean prediction error). Categories relating to ethnicity, sex and age were applied to the assessment of accuracy in order to compare these two approaches. Results indicate that Cameriere's European formula significantly underestimated age for both sexes (p < 0.001), with a mean difference of -

“…The obtained regression equations appear to be very useful for making predictions about GA, with each model explaining a very high percentage of total variance ( Table 2). The use of conventional regression analysis to relate the indicator variable (in this study: the longitudinal length in long bones) with age (in this study: gestational age) involves a systematic bias in age estimation: there is a tendency to overestimate age in younger individuals, and to underestimate it in older individuals [22,23]. Claude Masset [24] suggested that this trend is related to the age distribution of the reference sample but it has been also proposed that the use of age as the dependent variable in the regression analysis weakens the estimates [25].…”

A B S T R A C TThe estimation of gestational age (GA) on fetal remains can be an important forensic issue. Forensic specialists usually use reference tables and regression equations derived from reference collections, which are quite rare in what fetuses are concerned. Since these tools are mostly grounded on ultrasonographic measurements, which are known to differ from real bones measurements or are based on ancient literature, this study aimed the construction of tables and regression equations for the Portuguese population on the basis of diaphyseal bone length measurements (femur, tibia and humerus) of 100 fetuses of known GA, using post-mortem radiographs. There is a strong correlation between the longitudinal length of studied bones and GA; the femur exhibits the strongest correlation (r = 0.969; p = 0.000), followed by the tibia (r = 0.966; p = 0.000) and the humerus (r = 0.963; p = 0.000). Therefore it was possible to obtain regression equations and to build tables with reference values for each of the diaphysis analyzed.

“…Subsequent testing of the method or modifications thereof could mostly not demonstrate the same success rates [5,[42][43][44][45]. In general, it was found to be more accurate in the middle to older age groups and root transparency had a better correlation with age than periodontal recession.…”

Age estimation in unknown adult skeletons remains a considerable problem in forensic anthropology. In 1992, Lamendin and colleagues published a non-destructive method of age estimation on single rooted teeth. With this method, periodontosis and root transparency are judged against root height, and these are then used in regression formulae to estimate age.The aim of this study was to test the accuracy of the Lamendin method on a large sample of canines of South Africans, and if necessary to adapt the formulae for this population. A sample of known sex, age and population group was used. This included 537 upper and lower canines from 498 skulls, and included black males, black females, white males and white females. The age of the individuals ranged from 20 to 90 years. The original formulae gave relatively poor results, and in an attempt to obtain better accuracy the formulae were adapted with the current data. Even after adaptation of the formulae, the highest correlation between estimated age and actual age remained low (R 2 = 0.41), with mean errors ranging between 12 and 15 years. Periodontosis was better correlated with age than root transparency. The accuracy of the method was found to be much lower than what was originally published, but probably reflects biological reality and is on a par with other methods of adult age estimation.2
