Abstract

Introduction: Replacing missing teeth, selection plays a very important role in the outcome of the treatment as well as the patient satisfaction associated with that treatment. The objectives of the study were to evaluate whether there is a correlation between the relationship between bizygomatic width, interpupillary distance and distance between the inner and outer canthus of both the eyes with the total width of maxillary anterior teeth in this population. Material and Methodology: There were 99 Participants who were chosen in the study of which 50 were Male and 49 were Female. Correlation between bizygomatic width, interpupillary distance and distance between the inner and outer canthus of both the eyes with the total width of maxillary anterior teeth was done using Pearsons Correlation. Mean bizygomatic width, interpupillary distance and distance between the inner and outer canthus of both the eyes with the total width of maxillary anterior teeth was obtained and ANOVA was applied between Arch Form and Mean bizygomatic width, interpupillary distance and distance between the inner and outer canthus of both the eyes with the total width of maxillary anterior teeth. All the stats were done using IBM SPSS Version 21. (P<0.05) was considered to statistically significant. Results: There is a significant correlation between total width of maxillary anterior teeth with intercanthal distance (p <0.001) and interpupillary distance (p = 0.03). For all 99 participants the mean (SD) R. intercanthal distance was 1.54 (0.11) mm. The mean (SD) R. bizygomatic width was 2.49 (0.21) mm and it was found to be statistically different among the three arches (p=0.02). With the post hoc test, there was a statistical difference found between square and tapered arch form for bizygomatic width (p=0.006). The mean (SD) interpupillary distance was 1.31 (0.09) mm and it was found to be statistically different among the three arches (p=0.03). Post hoc test showed a statistically significant difference between square and tapered arch form for interpupillary distance (p=0.011). Conclusion: The null hypothesis was also rejected in this case because all the variables help choose anterior teeth as they have a high to moderate association with the maxillary anterior teeth.
