Aim: To evaluate the appearance of a hybrid layer in two seventh-generation bonding agents on human teeth with and without the application of 2% chlorhexidine.

Materials and methods: Class II cavities (MO-OD) were prepared on 12 human maxillary teeth. These teeth were divided into two groups (n = 6) to receive either of the two seventh-generation bonding agents. The bonding agent was applied in the mesioocclusal cavity. On the disto-occlusal cavity, 2% chlorhexidine was applied for 30 seconds before the application of the bonding agent. Teeth were sectioned mesiodistally with a slow-speed diamond disk and stored in water at 37°C for 30 days. The teeth were prepared for scanning electron microscope observation. The hybrid layer was measured by two variables – clear image of hybrid layer and presence of resin tags in tubules. Data were analyzed using chi-square and Kruskal–Wallis H tests.

Results: No statistically significant difference was found between the groups (p > 0.05).

Conclusion: CLEARFIL S3 performed better than the One Coat 7.0 bond.

Keywords: Chlorhexidine, CLEARFIL S3, One Coat 7.0 bond.
