Abstract:

Background Intercanthal distance is the distance between medial angles of palpebral fissures. It is half the interpupillary width. Intercanthal distance plays a crucial role  in the field of dentistry . Intercanthal distance has a significance in selection of teeth in the field of dentistry. Aim The aim of the study is to determine whether a relationship exists between the intercanthal distance and width of maxillary anterior teeth. Materials and methods The cross-sectional study  was carried out among the general public visiting as outpatients to a private dental college in chennai. Anterior Teeth measurement and intercanthal distance were measured using digital vernier callipers . Comparison between gender was estimated by an independent T test. The data collected was tabulated and analysed using IBM SPSS software (version 23). Association between different genders and the mean anterior teeth & intercanthal distance were assessed using Pearson’s chi-square test. Results There were 100 participants in the study, 28% were males and 72% were females. The mean value of intercanthal distance of males and females were 22.34 ± 1.88 and 21.7667 ± 1.97 respectively. The  mean  mesiodistal width of maxillary anterior teeth of males and females were 48.546 ± 0.84 and 47.567 ± 0.82 respectively. Conclusion This study showed that the intercanthal distance and mesiodistal width of maxillary anterior teeth in males were more when compared to females; though it was statistically insignificant.Both of these parameters are a good prognostic factor for determining the maxillary anterior width.
