牙齿的根管系统犹如交通枢纽,根管治疗即是将这些复杂的系统进行有效疏通,而根管治疗成功与否很大程度上取决于根管预备的质量[1]。与传统的不锈钢K锉相比,机用镍钛器械可快速、高效地预备根管,并可减少弯曲根管中台阶和穿孔的形成。1资料与方法1.1临床资料选取2012年8月至2013年8月在我院口腔科接受根管治疗的90颗患牙,患者年龄28~45岁,平均36.3岁,其中男40例,女42例。纳入标准:(1)确认为牙髓炎或根尖周炎。(2)根尖孔发育
Dental root canal system is like a transportation hub, and root canal therapy is to effectively clear these complicated systems. The success of root canal therapy depends largely on the quality of root canal preparation [1]. Compared with the traditional stainless steel K-file, the machine NiTi equipment can quickly and efficiently prepare the root canal, and can reduce the curvature of the root canal step and perforation formation. 1 Materials and Methods 1.1 Clinical data selected from August 2012 to August 2013 in our hospital dental root canal treatment of 90 teeth, the patient aged 28 to 45 years, mean 36.3 years, of whom 40 were males and 42 females example. Inclusion criteria: (1) confirmed as pulpitis or periapical periodontitis. (2) apical pore development
