Abstract :
AIM: Discrepancies in tooth width ratios could affect the excellence in the finishing of orthodontic cases. This study compared tooth width ratios in crowded and noncrowded dentitions with gender variation. METHODOLOGY: Tooth widths were measured from 200 dental casts (50 crowded and 50 spaced in male and 50 crowded and 50 spaced in female) using a digital caliper with a Vernier scale neared 0.1 mm. Bolton analysis was applied to calculate the tooth width ratios (anterior and total). Descriptive statistics, Student’s t–test, and chi square test were applied. RESULTS: There was no statistically significant difference found between the anterior and total tooth width ratios according to gender variation and dentition types (P>.05).A comparison between crowded and noncrowded dentitions irrespective of gender variation showed that there was statistically significant difference (p=0.038 and 0.005 respectively) present. Although both sums were larger in crowded dentitions, all differences were within the normal values proposed by Bolton. Differences between subjects with crowded and noncrowded dentitions were 0.94 and 0.62 mm for the excess of anterior and total upper tooth mass with respect to lower mass excess which can’t be considered clinically significant(less than one mm). CONCLUSION: No difference in the tooth width ratios according to interaction between gender and crowding was found.
