EVALUATION AND COMPARISON OF ARCH DIMENSIONS IN PATIENTS PRESENTING WITH AND WITHOUT MAXILLARY CANINE IMPACTION IN DAVANGERE POPULATION

OBJECTIVE To evaluate and compare the arch dimensions in patients presenting with and without canine impaction, in Davangere population. METHOD 120 subjects were divided into three groups of 30 each. Group 1- subjects with palatally impacted canine, Group 2- subjects with buccally impacted canine and control group. Model analysis was done for each patient. Arch dimensions such as intercanine width, interpremolar width, intermolar width, arch length and palatal height index was evaluated using a Korkhaus divider. RESULT Palatally impacted canine group showed statistically significant increase in inter canine width when compared to control. Buccally impacted canine showed a statistically significant reduction in inter-canine width values when compared to Palatally impacted canine. Buccally impacted canine had a statistically significant reduction in inter-premolar width values when compared to Controls. Buccally impacted canine showed statistically significant decrease in interpremolar width when compared to Palatally impacted canine. CONCLUSION There exists an association between arch dimensions and canine impaction. The cases with buccal canine impaction exhibit a reduced intercanine and interpremolar width and the cases with palatal canine impaction present with mild increase in intercanine width and interpremolar width but the variation in arch dimension is not as strongly associated as buccal canine impaction cases.
