Comparison of bracket retention of a resin modified glass ionomer cement and a resin based adhesive
Introduction: For many years composite resins have been used for bonding orthodontic brackets to the enamel tooth surface. Unfortunately due to the absence of an equal counterpart, the drawbacks of the resin adhesive needed to be endured. Over the past decade, resin modified glass ionomer cements have emerged as adhesives for bonding brackets to tooth surface with very fruitful results.
Material and Methods: This study was conducted at Islamic International Dental Hospital, in the department of orthodontics. The study design 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 with composite resin and RMGIC adhesive were compared for bracket retention over a period of one year.
Results: The obtained data was analyzed by using SPSS version 20. No statistically significant results were obtained. Statistically composite resin was not better than RMGIC in retaining orthodontic brackets.
Conclusions: RMGIC is as good as retaining brackets as composite and a great way to overcome the technique sensitive procedure, cytotoxicity and deleterious effects of composite resins in clinical use.
