Abstract

The purpose of this in vitro study was to evaluate the effect of a paste containing CPP-ACP, GC Tooth Mousse in preventing white spot lesions (WSL) during orthodontic treatment with fixed appliances. A total of 30 extracted human lower and upper premolars with no restorations, cracks, caries, hypoplastic areas or pliers impressions were collected for this study and used within one and six months. Enamel of buccal surface of the teeth was polished with pumice and water, rinsed and air dried. After etching the enamel surface with a 37% phosphoric acid solution for 15 seconds and rinsing for 10 seconds, teeth were dried. In this study Ricketts Universal Ultratrim (Dentaurum, Germany) stainless steal brackets for premolars were used. Each bracket was positioned over the mid point of the clinical crown on buccal surfaces of the prepared premolar. Con Tec LC (Dentaurum, Germany) was used as adhesives for bonding brackets in this study. The teeth were divided randomly into three groups, each one consisting of 10 teeth. The first group - control group included samples without any prevention; the second group included samples which enamel surface was treated with dental cream (GC Tooth Mousse) each day for 5 minutes in a period of 1 month and the third group included samples which enamel surface was treated with dental cream (GC Tooth Mousse) each day for 5 minutes in a period of 3 months. Teeth were stored in artificial saliva for one or 3 months. After that, the samples were prepared for SEM analysis (JEOL JSM 5300), using sputter technique in a vacuum evaporator. The appropriate area of enamel surface was analyzed in order to determine micro morphology changes in the structure of the enamel, on the place of previous brackets fixation. The application of GC Tooth Mousse dental cream after bonding appears to be beneficial in reducing the incidence of white spot lesions. Key words: white spot lesions, brackets, prevention
