人工唾液条件下3种自酸蚀粘接剂与牙本质粘接耐久性研究
Comparative study of three kinds of self-etching adhesives in terms of their dentin-bondTM ng strength and bondTM ng durability with dentin under the condition of the artificial saliva
摘要
Abstract
Objective To evaluate the bondTM ng strength and durability of three different self-etching adhesives under the condition of the artificial saliva with the micro-tensile test. Methods From May to July 2016, 24 freshly extracted, caries-free human third molars were selected and randomly divided into 3 groups, with 8 teeth in each group. Three selfetching adhesives were used, including Clearfil SE bondTM G-bondTM Plus and Single bondTM Universal. The standard specimens were made and selected, we divided the 160 standard specimens into two groups, 80 specimens in each group. The immediate micro-tensile bondTM strength and that after 6 months of soaking in artificial saliva were tested. Fracture type was observed with the microscope. Results The immediate micro-tensile bondTM strength of SE (n = 80), GBp (n = 80) and SBU (n = 80) were (55.70 ± 11.07), (52.85 ± 7.54) and (62.82 ± 8.70) MPa, respectively. The immediate micro-tensile bondTM strength of SBU group was higher than that of SE and GBp group, and the difference was statistically significant (P ＜ 0.05). After 6 months of preservation in the articificial saliva, the micro-tensile bondTM strength of SE, GBp and SBU group were as follows:13.51 ± 4.99), (43.53 ±6.82), and (49.13 ± 6.58) MPa, statistical differences among the three groups were significant. The different fracture modes were found in three groups after 6 months in the artificial saliva. In SE, all fractures occurred in interface. In 80 GBp cases, 16 fractures occurred in dentin, 4 in composite resins. In 80 SBU cases, 28 fractures were found in dentin, 8 in composite resins. Conclusion The microtensile bondTM strength of Single bondTM Universal is significantly higher than that of Clearfil SE bondTM and G-bondTM plus.Single bondTM Universal has strong bondTM ng durablility and can provide good bondTM ng effect in clinical application.关键词
