Abstract:

Aim: To compare the mean interpupillary distance and  mean mesiodistal width of central incisors among different genders. Background: For a successful rehabilitation of missing teeth, selection of teeth is of paramount importance. Among the anthropometric measurements, only interpupillary distance probably remains constant irrespective of age changes which give a definite guideline in selecting the size of the teeth. Materials and methods: A total of 102 participants, 74 females and 28 males of first year dental students from Saveetha dental college. Both male and female of age group 17-20 years having full complement of natural teeth were selected. To minimise sampling bias, the selection of participants was random. The mean interpupillary distance and  mean mesiodistal width of central incisors were measured using a digital vernier caliper. Data collected was tabulated and analysed using the Statistical Package for the Social Sciences (SPSS) software version 23.0 (IBM, Chicago, USA). Result: The mean interpupillary distances of males (66.91±2.0) were significantly greater than that of females (63.39±2.9). The p-value is 0.051. The mean Mesiodistal widths of maxillary central incisors were greater in  male (8.56±0.2) when compared to females (8.43±0.2                ). The p-value is 0.166. Conclusion: The present study concluded that there was a significant difference in mean interpupillary distance and mean mesiodistal width of maxillary central incisors between males and females. These parameters can potentially find its application in prosthetic rehabilitation  and forensic identification of individuals.
