摘要: 目的:研究十二烷基磺酸钠(SDSn)溶液对根管内Vitapex糊剂的清除效率。方法:通过X线目的:研究十二烷基磺酸钠(SDSn)溶液对根管内Vitapex糊剂的清除效率。方法:通过X线片计算根管冲洗前后Vitapex糊剂面积,比较不同冲洗方案下根管内Vitapex糊剂的清除率。选用直根管模块,筛选出SDSn清除根管内Vitapex糊剂最佳浓度;比较蒸馏水、1% NaClO、17% EDTA、7%马来酸(MA)、10%柠檬酸(CA)、1% SDSn等液体对直根管内Vitapex糊剂的清除效率;比较1% NaClO+H锉(HF)、1% NaClO+Gentlefile Brush(GF)、1% SDSn+HF、1% SDSn+GF等不同器械联合溶液对直根管内Vitapex糊剂的清除效率。选用25°弯曲根管模块,比较1% NaClO+双向开口冲洗针、1% NaClO+IrriFlex冲洗针、1% SDSn+双向开口冲洗针、1% SDSn+IrriFlex冲洗针等不同冲洗针联合溶液对弯根管内Vitapex糊剂的清除效率。结果:1% SDSn对根管内Vitapex糊剂清除率高于0.1% SDSn(P<0.05),与5%SDSn和10%SDSn比较无显著差别(P>0.05);1% SDSn对根管内Vitapex糊剂清除率均高于1% NaClO、17% EDTA、7% MA、10% CA(P<0.05);在直根管,Gentlefile Brush的使用显著提高了1% NaClO组的清除率(P<0.05),而并未显著提高1% SDSn组的清除率(P>0.05);在弯曲根管中下段,1% SDSn+IrriFlex冲洗针的清除率显著高于1% SDSn+双向开口针头(P<0.05)。结论:1% SDSn对根管内Vitapex糊剂有较好的清除效果;对于直根管,使用1% SDSn联合Gentlefile Brush能提高Vitapex糊剂的清除率;对于弯曲根管中下段,使用1% SDSn联合IrriFlex冲洗针头能有效提高Vitapex糊剂的清除率。

Abstract: Objective:?To investigate the clearance of SDSn solution on Vitapexpaste. Methods:?The area of Vitapex paste in the root canal before and after irrigation was calculated by X-ray films, and the clearance rate of Vitapex paste in the root canal under different irrigation schemes was compared. Straight root canal modules were selected,and the optimal concentration of SDSn for removing Vitapex paste in the root canal was screened out. The clearance efficiency of Vitapex paste in straight root canals by distilled water, 1% NaClO, 17% EDTA, 7% maleic acid (MA), 10% citric acid (CA), and 1% SDSn was compared. The clearance efficiency of Vitapex paste in straight root canals by different instruments combined with solutions such as 1% NaClO + H-file (HF), 1% NaClO+ Gentlefile Brush (GF), 1% SDSn + HF, and 1% SDSn + GF was compared. 25° curved root canal modules were selected, and the clearance efficiency of Vitapex paste in curved root canals by different irrigation needles combined with solutions such as 1% NaClO+ double-ended irrigation needle, 1% NaClO + IrriFlex irrigation needle, 1% SDSn + double-lumen flushing needle, and 1% SDSn + IrriFlex irrigation needle was compared. Results:?The clearance rate of Vitapexin 1% SDSn groupwas higher than that of 0.1% SDSn group (P<0.05), but there was no significant difference compared with 5% SDSn groupand 10% SDSn group (P>0.05). The clearance rate of Vitapex by 1% SDSn group was higher than that of 1% NaClO group, 17% EDTA group, 7% MA group, and 10% CA group (P<0.05). In straight root canals, the use of Gentlefile Brush significantly increased the clearance rate in 1% NaClO + GF group (P<0.05), but did not significantly increase the clearance rate in 1% SDSn + GFgroup (P>0.05). In the middle and lower segments of curved root canals, 1% SDSn + IrriFlex needle group significantly increased the clearance rate compared with 1% SDSn + double-lumen flushing needle group (P<0.05). Conclusions: 1% SDSn is efficient in removing Vitapex paste from root canals. For straight root canals, the combination of 1% SDSn and Gentlefile Brush can increase the clearance rate of Vitapex paste. For the middle and lower sections of curved root canals, the use of 1% SDSn in conjunction with the IrriFlex irrigation needle can effectively enhance the clearance rate of Vitapex paste.
