Background: Self-etching has been shown to be beneficial compared to the other resin sealants especially in pediatric practice. The present in-vivo study was designed to clinically evaluate the sealing ability and retention of the self-etching sealant compared to the conventional resin sealant. The aim was to evaluate and compare the retention and marginal integrity of the self-etch and acid etch sealant materials at three, six and twelve-month follow up.
