Evaluation of White Spot Lesion Development Using 3 Orthodontic Adhesive Systems

Jordan University of Science and Technology75 enrolled

Overview

The gaol of this randomized clinical trial was to compare the effect of self-etching primer bonding system and one step adhesive bonding system on the development of white spot lesions (WSLs) during fixed orthodontic therapy in comparison with the conventional 3 step bonding system. All participants will be bonded with similar fixed orthodontic appliances using each type of adhesives for the assigned group. WSLs will be monitored during the orthodontic treatment

Objectives: The objective of this clinical trial was to compare the effect of self-etching primer bonding system and one step adhesive bonding system on the development of WSLs during fixed orthodontic therapy in comparison with the conventional 3 step bonding system. Materials and Methods: Seventy five patients were randomly allocated into 3 groups (Group 1, conventional bonding system, n=25; Group 2, self-etch primer n=25; Group 3, primer mixed with the adhesive composite n=25). Quantitative light-induced fluorescence (QLF) was used to quantify WSL parameters. Images were captured and then analyzed before treatment; 2 months and 4 months after bond-up. Lesion area (Pixels), mean fluorescence loss (∆F) and the number of newly developed WSLs were compared within and between the 3 groups. The significance level was set at P ≤ 0.05.
