Abstract

Orthodontic appliances predispose to the accumulation of plaque due to the great number of retentive sites, which might lead to enamel demineralization adjacent to the accessories. Aim: To assess the effectiveness of a compomer for orthodontic bonding in preventing the formation of white spots around orthodontic brackets. Methods: Forty extracted human premolars were divided into two groups: control group (CG), in which conventional resin Transbond™ XT Light Cure (3M Unitek™) was used to bond the brackets; and experimental group (EG), in which the compomer Transbond™ Plus Color Change (3M Unitek™) was used. pH cycling was performed for 17 days to induce the demineralization process. Enamel on the buccal face was photographed under a stereomicroscope (at 10x magnification) before (t0) and after (t1) pH cycling. The images were used to compare demineralization between the groups by using a visual scale. Results: A statistically significant difference between control and experimental groups was found (p=0.004) showing that the compomer was more efficient than the conventional resin in preventing white spots. Conclusions: The compomer Transbond Plus Color Change was capable of inhibiting enamel demineralization adjacent to the bonding area of brackets. However, the inhibition halo did not exceed 1 mm.
