RESUMO
The skeleton plays an important role in sex determination in forensic anthropology. The skull bone is considered as the second best after the pelvic bone in sex determination due to its better retention of morphological features. Different populations have varying skeletal characteristics, making population specific analysis for sex determination essential. Hence the objective of this investigation is to obtain the accuracy of sex determination using cranial parameters of adult skulls to the highest percentage in South Indian population and to provide a baseline data for sex determination in South India. Seventy adult preserved human skulls were taken and based on the morphological traits were classified into 43 male skulls and 27 female skulls. A total of 26 craniometric parameters were studied. The data were analyzed by using the SPSS discriminant function. The analysis of stepwise, multivariate, and univariate discriminant function gave an accuracy of 77.1%, 85.7%, and 72.9% respectively. Multivariate direct discriminant function analysis classified skull bones into male and female with highest levels of accuracy. Using stepwise discriminant function analysis, the most dimorphic variable to determine sex of the skull, was biauricular breadth followed by weight. Subjecting the best dimorphic variables to univariate discriminant analysis, high levels of accuracy of sexual dimorphism was obtained. Percentage classification of high accuracies were obtained in this study indicating high level of sexual dimorphism in the crania, setting specific discriminant equations for the gender determination in South Indian people.

Disturbance in the organogenesis of tongue might lead to some malformations like tongue tie, bifid tongue and hairy tongue. Severe degrees of these anomalies may cause speech impairment or periodontal defects. The present study was done on patients of the southern coastal belt of India during the past two years, on gross tongue anomalies. The results of the present study reveal that occurrence of tongue tie is 0.2 percent and bifid tongue is 0.3 percent in the southern coastal population. Since great majority of these oral anomalies have genetic basis the purpose of the present report is to highlight that these anomalies can exist without any familial background and also to suggest that environmental factor may play a role in the etiogenesis of these anomalies.
La alteración en la organogénesis de la lengua puede dar lugar a algunas malformaciones como anquiloglosia, lengua bífida y lengua vellosa. Grados severos de estas anomalías puede provocar un trastorno del habla o defectos periodontales. El presente estudio se realizó, durante los últimos dos años, en pacientes de la franja costera del Sur de la India con anomalías graves en la lengua. Los resultados del estudio revelaron que, en la población costera del sur, la incidencia de anquiloglosia era de 0,2 porciento y de lengua bífida de 0,3 por ciento. Dado que la gran mayoría de estas anomalías orales tienen base genética, el propósito del presente informe fue poner de relieve que estas anomalías pueden existir sin ningún tipo de antecedentes familiares y también sugerir que los factores ambientales podrían jugar un papel en el etiogenesis de estas anomalías.
