Determination of proportional relationships between maxillary intercanine distance and various facial dimensions: A cross sectional study

The study was conducted on 231 subjects (101 males and 130 females) ranged from 15 years to 69 years in age, with all natural upper anterior teeth present in mouth having no caries, severe attrition, erosion, fracture or restorations were selected. Intercanthal distance (ICthD), intermedialcanthal distance (IMCthD), interpupillary distance (IPD), interalar width (IAW ), inter lip commissural distance (ICmD) and maxillary Intercanine distance from tip to tip (ICD) were measured with a venire caliper with an accuracy of 0.01 mm. Obtained data was entered into Microsoft excel program and various statistical calculations and tests were applied to find out correlation between above mentioned various facial measurements and maxillary intercanine distance in male and female subjects. The statistical results of this study showed that there was positive correlation between intercanthal distance and maxillary intercanine distance in both male and female subjects. Other facial measurements showed no statistically significant correlation with maxillary intercanine distance. Suggesting that the intercanthal distance can be used as a preliminary method to determine the width of the maxillary anterior teeth while constructing complete denture in edentulous patients.
