Abstract
Objectives: All studies performed periodontal distraction with interseptal bone cuts but no one performed it without interseptal bone cuts. Therefore the aim of the present study was to evaluate and compare the effect of periodontal distractor with and without interseptal bone cuts on the pulp vitality of the retracted canines. Methods: 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 by periodontal distractor with distal interseptal bone cuts (Group I), canine retraction by 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. An electrical vitality test was evaluated before and after the distraction procedure. Results: None of the teeth reacted negatively to the electrical vitality test that was performed one month after the completion of the distraction procedure. There was no clinical sign of discoloration or pulpal pain in any tooth. Conclusions: Canine retraction was accelerated effectively by periodontal distraction technique either with or without distal interseptal bone cuts. The electrical pulp tester was positive in both groups.
