Abstract

Background: Evidence-based information should be provided to clinicians to explain the effectiveness of hydrophilic and hydrophobic forms of resin based sealants (RBSs).

Aim: To assess and evaluate the retention and cariostatic effect of hydrophilic and hydrophobic RBSs in primary and/ or permanent teeth with at least a follow-up period of 3 months.

Materials and methods: Five databases were searched up to September 2021 for randomized and non-randomized clinical trials (RCTs and non-RCTs) that evaluated the retention and cariostatic effect of hydrophilic and hydrophobic RBSs. Two authors nominated the papers, extracted data, and assessed the risk of bias.

Results: By comparing the retention rate and caries incidence between groups, pooled-effect estimates of included articles were generated. After removing duplicates from the 2,810 titles found, only 1938 remained. Twelve of these were thoroughly examined. A total of 12 papers met the inclusion criteria in qualitative analysis: seven RCTs and five non-RCTs. Only ten studies were included in the meta-analysis: five RCTs and five non-RCTs. After 12 months of follow-up, no significant difference was found in the retention of hydrophilic and hydrophobic RBSs with and without a bonding agent. After 12 months of follow-up, no significant difference was found in the cariostatic effect of hydrophilic and hydrophobic RBSs.

Conclusion: There was no statistically significant difference in retention and the cariostatic impact was found between hydrophilic and hydrophobic RBSs.
