Abstract

Introduction: Prolonged treatment time in orthodontics has been the focus of attention of researchers since decades and many techniques have been suggested for accelerating tooth movement. The role of Vitamin D3 is among one of such suggested means but results are variables. Objectives: The aim of this clinical study was to determine the effect of Vitamin D3 on the rate and amount of orthodontic tooth movement in humans when injected locally at site. Materials and Method: A prospective split mouth clinical trial was carried out on 15 subjects who were indicated for bilateral therapeutic extraction of the first premolars followed by canine retraction in the maxillary arch. Vitamin D3 in a vehicle of local anaesthetic solution was injected into the buccal vestibule immediately distal to the canine to be retracted on experimental side; whereas on the contralateral side, only local anaesthetic solution was injected as control in the same site on the 7th, 21st & 47th days of canine retraction. The amount of canine retraction was assessed keeping maxillary palatal rugae as stable landmark and the values obtained were compared by pre- and post- canine retraction occlusograms. Results: The present study showed that experimental teeth that had received injections containing Vitamin D3 had moved considerably lesser than matched control teeth (p
