The relationship of interalar width, interpupillary width and maxillary anterior teeth width in Saudi population

This study was conducted to determine the relationship between interpupillary distance, interalar distance and the width of the six anterior teeth to be used as a guide during selecting the width of the six anterior teeth. 163 subjects were included in this study. A digital caliper used for facial and tooth measurements. The results showed a significant correlation between all measurements for the entire sample but when the sample divided into sex correlation found in female only, a significant difference between all measurements in both sexes was found. The average multiplying factor to estimate the width of the maxillary anterior teeth using interalar width was 1.56 in this study.
