Background: Interpupillary distance(IPD) is the distance between the centers of two pupils.  This measurement is necessary for replacing maxillary central incisors in the field of dentistry. Aim: To assess and compare the interpupillary distance  between the  different ethnic populations. Materials and methods: The cross sectional study was conducted among undergraduate students of a private dental college and hospital.The anatomical IPD was measured by using a digital vernier caliper. The digital vernier caliper needle  was placed on the center of eyebrows and the measurement was taken between two eyebrows which are straight above the center of pupils.  Statistical analysis was performed using SPSS Software version 23 by one way anova test. Result: There were 149 -participants in the study. About 16%. of them  were males and 75% of them were females. The mean inter pupillary distance in  south Indian population was assessed to 62.72 +or- SD. The mean  interpupillary distance in  North Indian Population was 62.52 +or- SD. although it is not significant (P= 0.310). Conclusion:The present study records  the varied interpupillary distance observed between different ethnicities. Interpupillary distance variations were observed not only by ethnicities but also with different  age groups.
