Clinical Trial Summary

evaluate the effect of periodontal distractor with and without interseptal bone cuts on the displacement of the maxillary canines, to assess the effect of two approaches on the pain intensity and on the pulp vitality of the retracted canines.


Description:

The sample of the study consisted of 32 canines in 16 female patients (16- 21 years old) requiring extraction of bilateral maxillary first premolars and canine retraction. They were divided into two groups: canine retraction was done by buccal periodontal distractor with distal interseptal bone cuts (Group I), canine retraction was done by buccal periodontal distractor without distal interseptal bone cuts (Group II). After bilateral maxillary premolar extraction in both groups inter septal bone cuts was done in group I only. Then the periodontal distractor was cemented and activated twice per day in both groups. Rate of canine retraction was evaluated before and after complete canine retraction direct in patient's mouth with digital caliper. Pain intensity was evaluated at 1st ,2nd ,4th and 7th days after activation through visual analog scale (VAS). An electrical vitality test was evaluated before and after the distraction procedure.
