Abstract

Introduction: Composite resins have been considered the gold standard for bonding orthodontic brackets to the tooth surface. Unfortunately, due to absence of a match counterpart, demineralization and white spot formation needed to be endured. With the introduction of resin modified glass ionomer cements, and their ability to release fluoride, bonding brackets to tooth surfaces have shown reduced incidence of white spot lesions.

Material and Methods: This study was conducted at Department of Orthodontics, Islamic International Dental Hospital, Islamabad. It was a randomized control trial using a split mouth technique. A sample of 40 patients were selected according to the inclusion and exclusion criteria and randomly distributed into two groups. Brackets bonded to tooth surfaces with composite resin and resin modified glass ionomer cement (RMGIC) adhesive were compared for formation of white spot lesions.  At the end of the study, pre-operative and post-operative photographs were compared to determine any signs of white spot lesions.

Results: The obtained data was analyzed by using SPSS version 20. The fluoride releasing properties of Glass Ionomer on reducing demineralization of enamel could not produce significant results when compared with composite resin.

Conclusions: No statistical significance could be appreciated in white spot lesion formation when comparison between bonding with composite resin and RMGIC use were ascertained.
