Abstract
PURPOSE: The effectiveness of resin-based pit-and-fissure sealants mainly depends on their retention and integrity over time. The purpose of this study was to evaluate retention rates of two different pit-and-fissure sealants compared with a flowable composite and a self-adhesive flowable composite over a 24 month period. METHODS: A split-mouth study design was used for all four permanent first molars of each patient. They were subjected to different kinds of sealants--either flowable composites or with fissure sealants. The flowable composites used were: flowable composite with an adhesive system (Tetric EvoFlow); and a self-adhesive flowable composite (Vertise Flow). The fissure sealants used were: a highly filled pit-and-fissure sealant (Fissurit FX); and a highly filled nano-hybrid pit-and-fissure sealant (Grandio Seal). Evaluation of the sealants was carried out at three-, six-, 12-, 18-, and 24-month follow-up visits. RESULTS: The complete retention rates were 95.7 percent for Tetric EvoFlow, 80.6 percent for Fissurit FX, 73.1 percent for Grandio Seal, and 62.9 percent for Vertise Flow. The retention rate of Tetric EvoFlow was significantly higher among all materials tested (P<0.05). CONCLUSION: The flowable composite used with an adhesive system was found to be superior to other sealing materials.
