BioPure MTAD对AH Plus根尖封闭性能的影响

Evaluation of BioPure MTAD as an endodontic irrigant on the apical sealing ability of AH Plus sealer in vitro

目的:评价BioPure MTAD作为根管冲洗液对根管充填糊剂AH Plus根尖封闭性能的影响。方法:选取人单根管牙44颗,随机分为A、B、C、D、E、F等6组,分别选用蒸馏水、1.3%NaClO、5.25%NaClO+17%EDTA、1.3%NaClO+BioPure MTAD和1.3%NaClO+3%EDTA等几组冲洗液进行根管冲洗。预备后进行根管充填,将所有实验样本染色,采用透明牙技术测量根尖微渗漏长度。采用SPSS12.0软件包对结果进行方差分析。结果:C组(1.3%NaClO)、D组(5.25%NaClO+17%EDTA)、E组(1.3%NaClO+BioPure MTAD)、F组(1.3%NaClO+3%EDTA)根尖微渗漏长度分别为(1.81±0.73)mm、(0.53±0.49)mm、(0.40±0.44)mm和(0.39±0.55)mm,C组微渗漏长度显著大于其他3个实验组(P<0.05);而D、E、F组根尖微渗漏情况无统计学差异(P>0.05)。结论:与临床常用根管冲洗液组合相比,BioPure MTAD冲洗根管对根管充填糊剂AHPlus的根尖封闭性能无明显不良影响。

PURPOSE： To evaluate whether BioPure MTAD could affect the apical sealing ability of AH Plus sealer in vitro.METHODS： Forty-four extracted single-rooted human teeth were randomly divided into six groups. The canals were treated with distilled water, 1.3%NaClO,5.25 %NaClO±17%EDTA,1.3%NaClO±BioPure MTAD and 1.3%NaClO±3%EDTA endodontie irrigants, respectively. After obturated, the teeth were made transparent and permitted dye penetration,then measured by using a stereoscopic microscope. SPSS 12.0 software package was used for One-way ANOVA. RESULTS： The microleakages lengths of obturated root canals in group C,D,E,F were （1.81±0.73）mm, （0.53±0.49）mm, （0.40±0.44）mm and （0.39±0.55）mm, respectively.Group C had significantly more leakage than group D,E,F （P〈0.05）, but there were no significant differences among group D,E,F （P〉0.05）. CONCLUSION： Compared with other endodontic irrigants which usually used in clinic, BioPure MTAD doesn＇ t adversely affect the apical sealing ability of AH plus sealer.
