Abstract

Introduction: Pit and fissures are the most common affected sites of caries occurance in newly erupted first permanent molars, however effectiveness of sealants are questionable in these teeth,due to difficulties in moisture control. The purpose of this study was to evaluate and compare the impact of two different categories of dentin bonding agents on sealant performance. Materials & Methods: 56 pairs of sealants (122 teeth) were placed bilaterally and randomly on the occlusal surface of both upper and lower first molars with either dentin bonding agent. With no preparation of the surface, Adper prompt or Excite both were applied as one layer and cured before sealant placement. Caries assessment was performed according to the CCC method (Color, Coverage, Caries) introduced by Deery et al. (2001) at 6-month intervals for 12 months. Partially or totally lost sealants were replaced at each recall visit. Data were analyzed using the Wilcoxon test. Results: Total etch and Excite were significantly superior in both retention and caries prevention (P=0.0001). Excite showed a significantly greater retention in the mandible than maxilla (P=0.027), whilst Adpaer prompt showed no difference between the jaws.. Among the teeth whose sealants were lost, progression of caries was greater in the Adper Prompt group. Conclusion: According to findings of this study, application of total-etch and bond is preferred to self-etch adhesives before sealant application in newly erupted first permanent molars.
