Resin-Infiltration of White-Spot-Lesions a Challenge for Orthodontic Bracket Bonding?

Objectives:
Smile aesthetics has become a great concern for patients. White-spot-lesions on children’s permanent dentition are often an aesthetic and structural concern for parents. However, nowadays treating these lesions with minimally invasive dentistry procedures by resin-infiltration is possible and frequently done as soon as the affected tooth finishes their complete eruption. Fixed orthodontic appliances are usually applied for tooth alignment and malocclusion correction also at a young age, but usually around the 10-16 years of age, when most of the permanent teeth are already erupted. Because in orthodontics there is a fair percentage of bracket bonding failure we wanted to see if some of it can be correlated to prior resin-infiltration procedures done on the teeth.
Methods: We conducted an observational retrospective pilot study on 120 orthodontic patients from a private practice and we found 8 that presented white-spot-lesions in their history, presenting a total of 27 affected teeth. Charts of these patients were studied for dates of resin-infiltration procedures, brand of orthodontic adhesive used and situations of bracket bonding failures during fixed orthodontic treatment. 5 of the patients, with 17 affected teeth underwent resin-infiltration procedures prior to their orthodontic treatment and 3 of them (with 10 affected teeth) opted to have orthodontics first.
Results: Although our study included only 27 teeth it was observed bracket adhesion failures more often and repeatedly in patients whom had previously had resin-infiltration procedures , and also using one particular type of adhesive, while no statistical differences have been found between the other adhesive technique used and patients whom didn’t undergo resin-infiltration procedures prior to orthodontics.
Conclusions: Our preliminary results indicate the need for further research in the field of bracket bonding failures due to resin-infiltrations.
