INTRODUCTION
The main aim of root canal treatment is cleaning, shaping and then obturating three dimensionally to prevent reinfection. This includes chemicomechanical cleansing by instrumentation and the use of irrigating solutions. Therefore, the purpose of this study was to compare the smear layer removal from root canal dentine subjected to two root canal irrigants, 17% EDTA and 0.2% Chitosan, a new irrigant using Scanning Electron Microscope.
METHODOLOGY
40 single rooted premolars were decoronated followed by instrumentation with I Race files and intermediate irrigation with 3% sodium hypochlorite and activation with ultrasonics. Then the samples were longitudinally sectioned and place in the respective test solutions and their controls for 5 minutes. Scanning Electron Microscopic evaluation was further carried out.
RESULTS
The results of the present study indicates that the Chitosan which was proved effective in removing smear layer.
CONCLUSION
A moderate concentration of 0.2% chitosan removes the smear layer with greater efficiency.
引言
根管治疗的主要目的是进行清洁、塑形，然后进行三维充填以防止再次感染。这包括通过器械进行化学机械清洁以及使用冲洗液。因此，本研究的目的是使用扫描电子显微镜比较两种根管冲洗剂（17%乙二胺四乙酸和0.2%壳聚糖，一种新型冲洗剂）对根管牙本质玷污层的去除情况。
方法
40颗单根前磨牙去除牙冠，然后使用I Race锉进行预备，并用3%次氯酸钠进行中间冲洗，同时使用超声波激活。然后将样本纵向切片，置于各自的测试溶液及其对照中5分钟。进一步进行扫描电子显微镜评估。
结果
本研究结果表明壳聚糖在去除玷污层方面被证明是有效的。
结论
0.2%的适度浓度壳聚糖能更高效地去除玷污层。
