Background Application of adhesive after acid etching may increase the retention of pit‐and‐fissure sealants and improve clinical effectiveness. Aims To clinically evaluate the retention, marginal discoloration and caries incidence of pit‐and‐fissure sealants applied using four bonding protocols: conventional acid etching, etch‐and‐rinse adhesive, multimode universal adhesive and self‐etch adhesive used after acid etching. Design In this split‐mouth design study, the four adhesive protocols were randomly assigned to the four erupted, non‐carious first permanent molars and involved 52 patients between 6 and 10 years of age. The sealants were evaluated at 3‐, 6‐ and 12‐month intervals. Statistical analysis was carried out using Friedman test and Kruskal–Wallis test. Results At 12 months, the retention rate was maximum in etch‐and‐rinse and universal adhesive groups (77.1%) followed by self‐etch adhesive (58.3%) and conventional acid etching group (45.8%). Dental caries was observed only in one tooth, and marginal discoloration was found to be the highest in conventional group and least in etch‐and‐rinse group. Conclusions Use of adhesives during pit‐and‐fissure sealant application does not significantly enhance sealant retention nor decrease marginal discoloration. Etch‐and‐rinse adhesive is advantageous only at short term.
