J Pak Dent Assoc Jan ;21(4):202-5.

OBJECTIVE To determine the difference between intercanine and intermolar width in class I,II&III malocclusion groups. METHODOLOGY: Initial orthodontic study casts of CLASS I, CLASS II DIV 1, CLASS II DIV 2 & CLASS III subjects coming to the Orthodontic Department of the Dr.Ishrat-Ul-Ebad Khan Institute Of Oral Health Sciences were selected. The sample included total 100 patients[25 in each group] including both male and female, with a mean age of 20years (17-25 years). The transverse widths of maxillary and mandibular dental casts was measured by universal digital calliper. Statistical analysis was done by using independent sample t-test for comparison among CLASS I, CLASS II DIV 1 and DIV 2 & CLASS III. RESULTS: Maxillary arch was found to be narrower in CLASS II DIV1. In CLASS II DIV 2 intermolar width is widest overall. Whilst in CLASS III malocclusion intercanine and intermolar width is significantly wide in mandible. Also intermolar width in maxillary arch was found to be wide in CLASS III. CONCLUSION In our study, mean intercanine and intermolar width is significantly different in CLASS I ,CLASS II DIV1. CLASS II DIV2 & CLASS III groups.
