Abstract
Objective:To study the effect of coating twice method of self etching adhesives on the microleakage of re⁃storing class V cavities. Methods:Eighty human third molars were divided into 2 groups,group 1 of S3 bond and group 2 of Xeno V. Each group was divided into 2 subgroups according to the adhesive coating times,coated once method in group A, coated twice method in group B. Class V cavities(3 mm × 2 mm × 2 mm)were prepared in the buccal surfaces of each tooth above the CEJ. There was a total of four groups,20 teeth and 20 cavities in each group. The cavities were filled with AP⁃X resin. The teeth of four groups were put into the constant temperature distilled water bath with the temperature of 37℃ for 24 h,soaked in 1% methylene blue solution for 24 h at room temperature,then cut them along the filling buccolingually and lon⁃gitudinally with carborundum disc and observed the dye penetration depth under the stereomicroscope. Results:The mic⁃roleakage value of coating twice method decreased compared with the coating once method both in S3 bond group and Xeno V group,but there was no statistical difference between the different coating methods(P>0. 05). When coating once method,S3 bond exhibited significantly lower leakage than Xeno V,there was statistically difference(P>0. 05). When coating twice, there was no statistical difference between S3 bond and Xeno V(P>0. 05). Conclusion:When restoring class V cavities,S3 bond and Xeno V coating once method can simplify the step.关键词
