This in vitro study investigated the effect of use of three dentine bonding agents: Scotchbond Multi‐Purpose Plus® (3M Dental Products, St. Paul, Minnesota, U.S.A.), Syntac® (Vivadent, Schaan, Liechtenstein), Optibond Dual Cure® (Kerr, Romulus, MI, U.S.A.) on microleakage and shear bond strength of a fissure sealant (Helioseal F®, Vivadent, Schaan, Liechtenstein) bonded to either dry or wet (saliva contaminated) enamels of primary teeth. Newly extracted 112 non‐carious primary teeth were sectioned and embedded in resin blocks. Eight groups were formed for each test. Each group consisted of 14 specimens. Group 1 and 2: fissure sealant was applied directly to etched enamel in dry and wet condition, respectively; Group 3 and 4: fissure sealant was applied onto etched and Scotchbond Multi‐Purpose Plus® treated enamel in dry and wet condition, respectively; Group 5 and 6: fissure sealant was applied onto etched and Syntac® treated enamel in dry and wet condition, respectively; Group 7 and 8: fissure sealant was applied onto etched and Optibond Dual Cure® treated enamel in dry and wet condition, respectively. The results revealed that the use of an enamel–dentine bonding agent under fissure sealant increased the bond strength and decreased the microleakage. The use of enamel–dentine bonding agents under sealant in moisture contaminated conditions gave better results than applying sealant alone onto non‐contaminated teeth. Finally, Scotchbond Multi‐Purpose Plus® yielded the best results for both tests.
