title: The effect of bonding agents on the microleakage and bond strength of sealant in primary teeth.
abstract: 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 Scotch-bond 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.
