Abstract

Clinician geneticists, surgical reconstructive specialists, and anthropologists of the skull and face depend heavily on canthal measures, which vary from person to person. The aim of this research is to compare the canthal measurements of two different ethnic groups in Nigeria. The study's sample consisted of people living in the Nigerian cities of Udu and Oleh, ranging in age from 18 to 45. The inner and outer canthal distances, or ICD and OCD, were expressed in millimeters. The standard formula was used to calculate the Canthal Index (CI). The data were statistically examined using the independent sample t-test. In statistics, a p-value of 0.05 was used to assess significance. The results demonstrated the sexual dimorphism of the Urhobo ethnic group in terms of Outer Canthal Distance (OCD), with males having a significantly higher mean value and Isoko males having a higher insignificant mean value than Isoko females. Males had slightly higher mean ICDs than females in both ethnic groupings. There was no statistically significant difference between the OCD and ICD scores of Urhobo males and females compared to Isoko males and females despite Urhobo males and females having higher mean values. While Isoko males had greater insignificant CI values than Isoko females, Urhobo females had higher insignificant CI values overall. Urhobo and Isoko respondents' mean CI differences were statistically different.
