Correlation between the width of maxillary anterior teeth and several facial landmarks of indonesian female and male

Prescribing the correct tooth size and proportion to prosthodontics patients is a challenge. Several studies state that the total width of six maxillary anterior teeth (WAT) can be predicted from intercanthal distance (ICD), interalar width (IAW) or commisural width (CMW). A recent study in the USA compares anterior tooth proportions among subjects, including Asian, with even sex distribution. However, it is known that craniofacial characteristics are subjected to environmental adaptations. Therefore, this study was performed to correlate the width of six maxillary anterior teeth and several facial landmarks of Asian living in Asia (Indonesia). Thirty-six females and 24 males (age 20 -35 y.o.) participated in the study. ICD, IAW and CMW were measured intraorally using caliper three times for each. WAT was measured by adding mesiodistal width of each anterior tooth. The means and standard deviations of each variable were calculated. Correlations between variables were analyzed using Spearman/Pearson correlation coefficient. The mean values were significantly different for male and female for CMW (P = 0.000), IAW(P = 0.000), ICD (P = 0.007) and WAT (P = 0.000).Male has a statistically significant strong correlation between WAT and CMW (P = 0.004, r = 0.53). These results suggested that for this particular population, for males the width of six maxillary anterior teeth is strongly correlated with commissural width.
