Abstract

 Objectives: The aim of this study was to determine the correlation between the Carabelli trait and the crown perimeter of the first and second upper molars. Methods: With the cross - sectional and analytic study design, the sample consisted 45 upper molars (no Carabelli (16 teeth); pit, groove form (16 teeth); tubercular form (13 teeth)). Crown perimeter were determined by drawing a curve following the crown contour based on the digital image. The drawn contour is measured by Autocad software 2007. Results: The crown perimeter of the first and second upper molars were significant different (p<0.05) between three Carabelli forms, respectively: no Carabelli (38.5mm and 38.4mm); pit, groove form (39.6mm and 39.7mm); tubercular form (40.7mm and 40.8mm). There were correlation between the crown perimeter of the first and second upper molars and Carabelli trait (r=0.655 and r=0.783), p<0.01. Conclusion: There were positivecorrelation between three Carabelli forms and the crown perimeter of the first and second upper molars.
