Retention of three fissure sealants and a dentin bonding system used as fissure sealant in caries prevention: 12-month follow-up results.

Abstract

BACKGROUND: Bonding agents could be used as fissure sealants. This study compares the retention three fissure sealants (Delton, Delton Plus and Concise) and a filled dentin bonding system (Optibond Solo). METHODS. Fifty-six children aged 7-8 years received fissure sealants either in the four permanent first molars, in the four deciduous second molars, or in all eight of these teeth. Every child received a different sealing material in each quadrant on a random basis. Clinical evaluation at 12 months was performed by a single blind examiner, and the retention was classified as either a success (total retention) or a failure (partial retention or not present). RESULTS: There were no statistically significant differences among the four materials in permanent maxillary molars or deciduous molars. In permanent mandibular molars, Optibond Solo showed a lower percentage of retention (40.9%), significantly different (p=0.002) to that of Delton (89.5%), Delton Plus (87.5%) and Concise (76.5%). CONCLUSION: One bottle dentin bonding system used as a sealant does not improve the retention of conventional fissure sealants. CLINICAL IMPLICATION: Because of the scarcity of studies on the use of dental adhesives as sealants, further studies are warranted for the final support of that conclusion.
