A Comparative CT Evaluation of the Amount of Root Resorption in Self-ligating Versus Conventional Brackets

Study Overview
=================
Brief Summary
-----------------
Aim: The aim of the study was to evaluate and compare the extent of root resorption in the maxillary and mandibular anterior teeth during orthodontic treatment with the use of different types of brackets. Materials and methods: The study consisted of 21 patients (11 males and 10 females) within the age group of 16-25 years, having bimaxillary protrusion. They were divided into three groups. In Group 1- Conventional brackets, Group 2- Self-ligation brackets:Smart Clip (Passive), and in Group 3 Self-ligation brackets: Empower (Active) were bonded. Computed Tomography scans and Orthopantomograms were taken before start of treatment and after six months of retraction. Root resorption is computed as the difference between the pre treatment total tooth length and the post treatment total tooth length.
