Efficacy of fissure sealants depends upon their retention. Meta-analyses have demonstrated that resin-bonded sealants (RBS) are better than glass ionomer sealants on both counts. In this review, 124 studies relevant to RBS retention were identified, and 31 were clinical trials suitable for inclusion: 16 comparing 2 different types of RBS, and 15 focusing on suitable protocols for sealant application.
In many cases, study methodology was not clearly described, making evidence of low quality. Retention rates of autopolymerised and light-cured RBSs did not differ significantly at any follow-up interval. With regard to clinical procedure, there was no significant meta-analysis effect for tooth cleaning method, enamel preparation or adhesive agent application. Isolation method was important only with fluoride-containing sealants, the retention of which was improved with a rubber dam. The authors comment that further and better studies are needed in the future.
