BACA, Pilar et al. Retention of three fissure sealants and a dentin bonding system used as fissure sealant in caries prevention: 12-month follow-up results. Med. oral patol. oral cir.bucal (Internet) [online]. 2007, vol.12, n.6, pp.459-463. ISSN 1698-6946.

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.
