“…Thus the sample size was considerably reduced. No other dental measurements were used because successful sex allocation was proven to be less reliable than the results based on canine measurements (Ditch and Rose, 1972;Işcan and Kedici, 2003;Cardoso, 2008). Furthermore, in the Bom Santo series, canines were numerically one of the better represented teeth.…”

“…His results indicate that the bucco-lingual diameter (BLD) of the permanent canine provides the best sex allocation (100% for the upper canine and 86% for the lower canine). Others also found a very significant sexual dimorphism in the BLD of canines in samples of individuals of known-sex (Yamada and Sakai 1992;Işcan and Kedici, 2003;Cardoso 2008;Rai et al 2008;Ruengdit et al 2011;Zorba et al 2011) and on an archaeological sample of individuals whose sex could be ascertained from their pelves and long bones (Ditch and Rose, 1972). In contrast, Vodanovic et al (2007) failed to do this in a sample of medieval Croatians of unknown sex.…”

Estimating sex on large assemblages of commingled skeletal human remains is challenging because it prevents the systemic observation of the skeleton and thus reduces the reliability of sex-ratio estimation. In order to tackle this problem, the applicability of sample-specific odontometric methods was assessed on the human skeletal remains from the Middle Neolithic cave necropolis of Bom Santo in Portugal. We present an approach that confirms some of the assumptions -the normal distribution of the data and the 1:1.5 sex ratio -indicated by Albanese et al. (2005) for the application of sample-specific methods. These assumptions are often difficult to assess in archaeological samples and thus prevent the use of sample-specific methods.The mean bucco-lingual diameter of 51 lower right canine teeth was used as a cut-off point to discriminate between sexes within a sample from Bom Santo. Before that, Shapiro-Wilk statistics was used to confirm that the distribution of the data in a sample of 51 lower canine teeth was normal. In addition, the range and central tendency of the data were compared to other samples for which the sex of the individuals was known in order to confirm that those parameters were consistent with those of a sample presenting a balanced sex ratio. The canine sex estimations were then compared with the sex estimation obtained from mandibles where canine teeth were still in situ (n = 8). No clear disagreement between the two methods was found thus demonstrating good potential of this method for sex estimation and for the sex ratio estimation in commingled human skeletal remains. Results indicated that sex ratios in Room A and Room B at Bom Santo were quite different. This indicates that the two locations may have been used in a different way according to sex.

“…The purpose of this procedure is, first, to estimate precisely the age of the skeletons, because the timing of tooth formation (the benchmark for aging) is affected by sex (Smith, 1991); and second, to elucidate any sex differences in growth pattern. Although inferring the sex of an immature skeleton before the onset of puberty is generally difficult, discriminant function analysis based on dimorphism of permanent tooth size is known to be effective (Ditch and Rose, 1972;Garn et al, 1979;Hanihara and Koizumi, 1979;Beyer-Olsen and Alexandersen, 1995;Matsumura, 1998). The results of sexing modern specimens of known sex by this method have also shown its efficacy.…”

This study investigated the growth patterns of morphometric features of ancient people determined from historic and prehistoric skeletal remains. Subadult skeletons from the Yayoi, medieval, and modern periods were used. The age of each skeleton was estimated from dental formation standards. Measurement methods followed standard anthropological methodology established for the adult skeleton. Quadratic regression formulae that showed the highest coefficient of determination were chosen to evaluate plausible growth patterns. The results are as follows. (1) The neurocranium of the medieval people showed a possible difference in growth pattern compared with the modern people. The cause of this difference is discussed in relation to brachycephalization. (2) In all the groups studied here, over the course of growth, the height of the lower facial region increases much more than that of the upper facial region. With this change, the contour of the orbit changes into a relatively wider-lower shape, and the contour of the nasal cavity shifts with age from a relatively wider-lower to a narrower-higher condition. (3) In all the groups studied here, over the course of growth, the nasal bones become more curved transversely. However, the angle of the frontal process of the maxilla, which forms the lateral sides of the nasal bones, changes only slightly, if at all. (4) Secular differences in mandibular morphology related to chewing stress emerge at an older age than do the regional differences of the Yayoi people's facial morphology, an effect that is probably related to genealogy. (5) Analysis of femur length suggests that the Yayoi people in the northern Kyushu and Yamaguchi region experienced less growth disruption than did the other people studied here.

Introduction: One of the critical steps in the process of identification is the sex determination of an unknown individual. Many studies have shown that sex can be determined using the human skeleton, especially by examining the pelvis and skull. Odontometric analysis of the human sexual variation has been less investigated, especially of primary dentition. Aim:To verify the presence of sexual dimorphism in primary teeth of local population of Faridabad, Haryana, India. Materials and Methods:The research was performed on dental casts of 500 children (250 boys and 250 girls, age range 3-5 years). Mesiodistal and buccolingual crown dimensions of maxillary and mandibular primary teeth were measured with a digital Vernier's caliper and were analysed for sexual dimorphism. Mann-Whitney-U test was used to check the statistical significance of difference in tooth dimensions among boys and girls.Results: Differences were found in the mean values of mesiodistal and buccolingual diameters of primary teeth, in which boys generally had larger crown diameters than girls. Conclusion:Primary teeth may be used as an additional tool for sex identification of juvenile skeletons where other dimorphic features are not much developed.www.jcdr.net Akshara Singh et al., Demystifying the Mysteries
