Evaluation of pit-and-fissure sealants placed with four different bonding protocols: a randomized clinical trial
of adhesive after acid etching may increase the retention of
pit-and-fissure sealants and improve clinical effectiveness.
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.
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.
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.
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
