Abstract:

Abstract：Objective To evaluate the microleakage and penetration ability of zirconium oxide inlays using different self-etching bonding agents in vitro. Methods Forty caries-free extracted human third molars were randomly divided into four groups with ten teeth each. Class V cavities were prepared on the buccal surfaces of forty human extracted third molars using diamond burs. The zirconium oxide inlays were placed with Adper Singlebond 2，ClearFil SE Bond，Multilink Sprint and Adper Easy One. The microleakage scores were examined on the occlusal and gingival margins at 30× magnification after each sample was stained. Results Statistically significant differences were observed between the groups in both occlusal and gingival margins. Microleakage scores of Multilink Sprint were significantly higher than other groups on both margins. Group of ClearFil SE Bond and Adper Easy One showed no statistical differences with etch-and-rinse resin cement. Conclusion ClearFil SE Bond and Adper Easy One show comparable microleakage results with etch-and-rinse resin cement.
