摘要

研究目的本研究旨在比较一种实验性根管冲洗剂和 17% 乙二胺四乙酸去除根管冠部、中部和根尖部涂抹层的效果:本研究选取了 90 颗人类单根上颌和下颌牙齿。这些牙齿被随机分为以下两个实验组和一个对照组:A 组(无患子乙醇提取物)、B 组(17% EDTA)和 C 组(蒸馏水)。所有三组的根管都是用不锈钢 K 型锉通过标准的后退技术制备的,并用 5.25% 的次氯酸钠进行灌洗。冲洗后对牙齿进行装饰,将其纵向分成两半,使用扫描电子显微镜(SEM)观察涂抹层的数量,采用三点评分法。观察结果在治疗前后都有记录。采用非参数检验进行比较,P 值 ⩽ 0.05 被认为具有统计学意义:A 组的 30 颗牙齿中有 27 颗牙齿的冠状部分的涂抹层被完全去除,A 组的 24 颗牙齿和 19 颗牙齿的中间和根尖部分的涂抹层被完全去除。在 B 组中,发现冠状区、中间区和根尖区分别有 24 颗、21 颗和 3 颗牙齿完全没有涂抹层。组内比较显示,A 组冠状面、中部和根尖三分之二处的涂抹层去除率存在显著差异(p = 0.002)。同样,B 组也发现了明显差异(p = 0.001);但 C 组在牙管的三个部分都发现了严重的污垢层:结论:与 17% EDTA 相比,无患子乙醇提取物在清除根管内的涂抹层方面具有更高的功效。

Comparative evaluation of Sapindus Mukorossi extract with 17% EDTA on smear layer removal in various parts of the tooth root.

Objectives: This study aimed to compare the effectiveness of an experimental root canal irrigant and 17% Ethylene-di-amine tetra acetic acid for removal of the smear layer in the coronal, middle and apical portions of the root canal.

Materials and methods: Ninety human single rooted maxillary and mandibular teeth were selected for this study. The teeth were randomly divided into two experimental groups and one control group as follows: Group A (Ethanolic extract of Sapindus Mukorossi), Group B (17% EDTA), and Group C (Distilled water). The root canals of all three groups were prepared with stainless steel K-files by means of the standard step-back technique and irrigated with 5.25% sodium hypo chloride. The teeth were decoronated, following the irrigation and divided longitudinally into two-halves and visualized using scanning electron microscope (SEM) for the amount of smear layer present utilizing the three-point score system. The observations were noted both before and after the treatment. Nonparametric tests were applied for the comparison and p-value ⩽ 0.05 was considered as statistically significant.

Results: It was evident from that smear layer was completely removed in coronal portion of 27 out of 30 teeth in-group A. For middle and apical areas of group A, 24 and 19 teeth showed complete smear layer removal. In-group B it was found that there were 24, 21, and 3 teeth at coronal, middle and apical, areas respectively where smear layer were completely absent. Intra group comparison showed a significant difference (p = 0.002) in smear layer removal was found for group A at coronal, middle and apical thirds. Similarly, a significant difference (p = 0.001) was also found for group B; however heavy smear layer was found among the three parts of the canal for group C.

Conclusions: Ethanolic extract of Sapindus Mukorossi have higher effectiveness in removing the smear layer from the root canal in comparison to 17% EDTA.
