氟离子导入降低根充微渗漏的实验研究
Experimental study of the fluoride ion importing diminished the occurrence of microleakage after root canal
摘要
Abstract
Objective:To study the effect of Fluoride ion imported in the occurrence of microleakage after root canal filling.Method: 18 size identical extracted teeth with single straight canals were selected,and they were randomly divided into fluoride ion imported group、fluoride ion imported and calcium phosphorate cement (CPC) group and control group.The fluoride ion imported group used fluoride ion to import after root preparation then filled root canal.The fluoride ion imported and CPC group used fluoride ion to import, besides used calcium phosphorate cement to scribble the wall, and then filled root canal.And the control group filled root canal directly after root preparation.Indexed of the length of dyestuff's penetration in transparent teeth, the data was processed using SPSS 17.0 software for analysis of variance.Result: The length of microleakage: The fluoride ion imported group is (2.6±1.6)mm, the fluoride ion imported and CPC group (2.1±1.6) (mm),the control group is (5.8±3.6)mm.The fluoride ion imported group is less than the control group (P ＜0.05),the different is obvious; the fluoride ion imported and CPC group is less than the control group (P ＜0.05), the different is obvious; The fluoride ion imported group is less than the fluoride ion imported and CPC group(P ＞0.05),the different is not obvious.Conclusion: ①The method of fluoride ion importing can diminish the occurrence of microleakage.②Fluoride ion imported and used calcium phosphorate cement to scribble the wall can diminish the occurrence of microleakage, though no different with the fluoride ion imported directly.关键词
