ABSTRACT Cranial, facial measurements and indices are used to estimate the sex and different shapes of head, and face. It is highly important for Anatomists, forensic scientists, plastic surgeons, physical anthropologists. Six craniofacial indices namely, head length, head breadth, cephalic index, face length, face breadth, facial index were calculated. Method: The present study was performed on 100 male medical students of south India of 18-23 year age groups, anthropometric points were measured by using spreading, sliding caliper. Result: The present study showed the correlation is statistically significant between the cephalic and facial indices in males. Conclusion: predominant head type in males was Dolico cephalic in 19 year age group. Key words: Craniofacial indices, Dolicocephalic. Anthropometric points, Correlation. INTRODUCTION The Study of Humankind, physically, and concern to explain the functional significance of culturally is known as Anthropology. And it has bones, and the normal features of bone and its been developed by the following biologists measurements are described by Traditional Samuel George Morton, Charles Darwin and physical anthropology. Understanding the Alfred Russell Wallace and Comte De Buffon, processes of the mechanism responsible for a Paul Broca, John Frederick Blumenbach. specific trait is important and should be given Classical & New Physical Anthropology : due attention than to make a simple statement Methodological approach of physical about its presence or absence .It necessitates anthropology1 is primarily based on compute the development of descriptive, quantitative indices, Statistics, defined measurements. methods. Physical anthropology is concerned However, the recent technical advancement and with the direction of change age groups, and realization of role of genetics in anthropology, among individuals of past and present. It the global acceptance of anthropometry is linked continues to be study of biological variation and with genetic heterogeneity to understand the human evolution. And Genetic differences and variability of traits. The traditional physical environmental modifications are responsible for anthropology concerns to describe the features of the changes of sources, like the age group of bones, whereas New physical Anthropology individuals past to present. Human biology is 439 Praveen et al., Int J Med Res Helath Sci. 2013;2(3):439-446 approached by the physical anthropology with Human populations were characterized as either emphasis on humanity. Since cultural context is Dolicocephalic (long headed), Mesaticcephalic considered as basic key to understanding, and (Moderate headed), Brachycephalic (Short proper appreciation of the problems of human headed). These were earlier issues on the role of evolution. Hence the physical anthropology is cephalic index in determining the race and concerned with the communication of mapping of the ancestral population. The lack of environmental2 and socio-cultural factors. plastic evidence9 led to implementation of Physical anthropology is important in forensic advanced techniques in 2002, 2003 and provided sciences. It made some significant contributions, a genetic back drop in head shape10-13. and also age and sex have determined by Cephalic indices: Cephalic index is derived individual characterization. Physical from the Greek word “ Kephalic” meaning anthropology helps in the fields of “Head”, The Greek work “ ikos” meaning dermatoglyphics, serology, osteology, “Pertaining to” and the Latin word “Index” osteometry, and solves the problems of forensic meaning” that which points out”. Header length science3. is the distance from the glabella to opistocranion. Cephalic index and physical anthropology : And head breadth is the distance between two The cephalic index is nothing but the ratio of the irons. maximum breadth of the head to its maximum Formula: Cephalic index (CI) = [Head width/ length. Sometimes multiplied by 100 for Head length] X 100 convenience. It was given by Ander Retzius According to Frankfort agreement of 1882 , (1796-1860). In Twentieth century the index martin and smaller classification14. Skulls can be widely used by anthropologists to categorize classified on the basis of cephalic indices, human populations.
