Variation of facial parameter interzygomatic distance between kumaoni and terai ethnic groups in Uttarakhand region

Background and Objectives: Forensic Anthropology is one of the most important and valuable sections of medical human anatomy. The objective of this study is to use a few facial indices namely Interzygomatic distance used to predict anthropometric relationships between the ethnic groups with the help of anthropometric tools. The aim of this study is to observe the variation of facial indices in different ethnic groups of hilly peoples of the Uttarakhand region. Methods: After proper searching of past published literature databases, statistical analysis was applied to get proper findings. This study has been carried out from the year 2021 to May of the year 2022. The study sample comprised randomly selected (100; 50 males + 50 females) Kumaoni and (100; 50 males + 50 females) Terai ethnic groups subjects from overall two hundred (200) subjects of my study from remote areas of tribes of Uttarakhand region born and brought up in Uttarakhand region aged 21 years and above up to 35 years young subjects, have been chosen for the reason that by this age, there is the completion of facial skeletal growth by ossification of bones. Result: With the help of reviewing most of the papers of past publications, we analyzed some of the essential final results in our present study: the linear regression equation derived for the Interzygomatic distance. The statistical analysis becomes statistically significant in Terai females (0.02 (S)) but in Kumaoni males (0.09 NS), Kumaoni females (0.2 NS) and Terai males (0.2 NS) it becomes nonsignificant. Discussion and Conclusion: In this study, the p-value is 0.2797 in Kumaoni females and 0.0913 in Kumaoni males, in the case of females the p-value indicates that the result is statistically significant. In the case of Kumaoni males, the p-value is more than 0.05; it is statically nonsignificant. The p-value is 0.0279 in Terai females and 0.2678 in Terai males. In the case of males and females both, the p-value is less than 0.05, in the case of males and females, the p-value indicates that the result is statistically significant. Interzygomatic distance is a very good parameter to observe the facial widths in hilly people like Kumaoni and Terai.
