【摘要】：目的:Er:YAG激光備洞和傳統(tǒng)的渦輪鉆針備洞,使用不同粘接系統(tǒng)和界面處理方式,對(duì)乳牙樹脂充填的微滲漏效果進(jìn)行研究。方法:50顆乳牙隨機(jī)分為5組,第1組:渦輪鉆針預(yù)備+全酸蝕粘接充填;第2組:渦輪鉆針預(yù)備+自酸蝕粘接充填;第3組:Er:YAG激光預(yù)備+全酸蝕粘接充填;第4組:Er:YAG激光預(yù)備+自酸蝕粘接充填;第5組:Er:YAG激光預(yù)備后不酸蝕+配合全酸蝕粘接劑充填,對(duì)不同組進(jìn)行微滲漏體視顯微鏡檢查。結(jié)果:渦輪鉆針+全酸蝕組和渦輪鉆針+自酸蝕組的微滲漏分別高于Er:YAG激光+全酸蝕組和Er:YAG激光+自酸蝕組(P0.05);渦輪鉆針+全酸蝕組與Er:YAG激光+不酸蝕組的微滲漏差異無(wú)統(tǒng)計(jì)學(xué)意義。Er:YAG激光預(yù)備的3個(gè)組中,全酸蝕組和自酸蝕組的微滲漏都低于不酸蝕組,但組間差異無(wú)統(tǒng)計(jì)學(xué)意義。結(jié)論:激光并不能代替全酸蝕劑的作用,激光照射后使用自酸蝕粘接系統(tǒng),充填體的邊緣適合性更好,微滲漏小。
[Abstract]:Objective to study the microleakage effect of resin filling in deciduous teeth by using different bonding systems and interface methods. Methods Fifty deciduous teeth were randomly divided into 5 groups: group 1: turbine drill needle preparation for total acid bonding filling, group 2: turbine drill needle preparation for self-etching bonding filling, group 3: er: YAG laser preparation for total acid etching filling; Group 4: er: YAG laser prepared self-etching bonding filling, group 5: er: YAG laser preparation did not acid-etching combined with total acid adhesive filling, different groups were examined by microleakage stereoscopic microscope. Results: the microleakage of the total acid etching group of turbine drill needle and the self-acid etching group of turbine drill needle were higher than that of Er:YAG laser total acid etching group and Er:YAG laser self-acid etching group P0.05.The microleakage of turbine drill needle total acid etching group and Er:YAG laser non-acid etching group was higher than that of Er:YAG laser self-acid etching group. The difference was not statistically significant. Er: YAG laser preparation of the three groups, The microleakage of whole acid etching group and self acid etching group was lower than that of non acid etching group, but there was no significant difference between the two groups. Conclusion: laser can not replace the effect of total acid etch agent. The self-etching bonding system is used after laser irradiation. The edge of the filling body is more suitable and the microleakage is small.
