Aims & Objectives: This study was designed to compare the 5th and 7th generation bonding agent’s vis a vis tensile bond strength on cut and uncut enamel surfaces and microleakage in class V cavities prepared in enamel. Material and methods: 60 extracted human mandibular molars were selected and randomly divided in to six groups. Four groups were used for tensile bond strength study, two groups each were bonded with 5th and 7th generation bonding agent on cut and uncut enamel surfaces and two groups were used for microleakage study. For microleakage study, class V cavities prepared on buccal surfaces were restored with 5th or 7th generation bonding agents. The restored teeth were stored in 100% humidity at 37 0 C for 24 hours and thermocycle between 5 0 C and 550 C for 100 cycles. Tensile bond strength was measured in Universal testing machine and microleakage was determined by dye penetration observed under stereomicroscope. The data were statistically analyzed. Results: For both cut and uncut enamel surfaces, 5th generation bonding agent showed a significantly higher tensile bond strength value (P<0.05). No significant differences among the adhesives were found in terms of microleakage.
