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

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.
