The aim of this study was to evaluate effect of different techniques of enamel etching on shear bond strengths (SBS) of fissure sealants. Fifty extracted non-carious third molars were cleaned with fluoride-free pumice and root sections 2mm below cementoenamel junction were taken. Coronal sections were embedded in resin, and buccal/ lingual surfaces of crowns were flattened to create an enamel surface area that was 3mm in diameter. The specimens were randomly assigned to 1 of 5 groups with 10 teeth each. Group1 35% orthophosphoric acid–etching (20sec); Group2 a fissurotomy–bur (Fissurotomy Micro–NTF); Group3 Erbium, Chromium:yttrium-scandium-galliumgarnet (Er,Cr:YSGG) laser 2W laser etching (20sec–20Hz); Group4 Er,Cr:YSGG laser 2W laser etching (20sec–40Hz); and Group5 20sec air-abrasion w..
