【摘要】：目的:比较采用充填器与HAWE牙体颈部成型片对楔状缺损牙进行光固化复合树脂充填成型治疗后充填体边缘微渗漏情况。方法:取新鲜离体双尖牙40颗,在颊侧颈部釉牙骨质界处制备标准V类(3mm×2mm×2mm)洞型,随机分成2组,A组采用不锈钢两头扁充填器,B组采用颈部成型片行复合树脂充填治疗。样本经冷热循环后,在2%亚甲基蓝溶液中染色24h,将充填体正中颊舌向纵行剖开,立体显微镜下观察修复体边缘染色情况,采用Image-Pro plus 6.0图像分析软件测量微渗漏深度。结果:两种方法均有微渗漏现象发生,A组边缘微渗漏深度为(0.641±0.370)mm,B组边缘微渗漏深度为(0.395±0.462)mm。两种方法树脂充填后边缘微渗漏程度及深度差异均有统计学意义(P0.05)。结论:虽然两种方法均不能消除充填体边缘微渗漏,但用颈部成型片的边缘封闭性明显优于传统充填器,而且操作简单,方便,节省时间,适合临床推广。
[Abstract]:Objective: to compare the edge microleakage of wedge-shaped defect teeth treated with HAWE and HAWE. Methods: 40 fresh isolated bicuspid teeth were collected. Standard V type 3mm 脳 2mm 脳 2mm) cavities were prepared at the bony boundary of the buccal neck enamel teeth. Group A was randomly divided into two groups: group A was treated with composite resin filling with stainless steel double end flat filling device and group B was treated with composite resin filling after cold and hot circulation. After staining in 2% methylene blue solution for 24 hours, the median buccal tongue was dissected and the edge staining of the prosthesis was observed under stereoscopic microscope. Image-Pro plus 6.0 image analysis software was used to measure the microleakage depth. Results: the microleakage depth at the edge of group A was 0. 641 卤0. 370 mm mm. the depth of microleakage at the edge of group B was 0. 395 卤0. 462mmm. after resin filling, the depth of microleakage at the edge of group A was 0. 395 卤0. 462mmm. the depth of microleakage was 0. 395 卤0. 462mmmm. There were significant differences in degree and depth between the two methods (P 0.05). Conclusion: although the two methods can not eliminate the microleakage at the edge of the filling body, But the edge closure of the cervical plastic film is obviously superior to that of the traditional filling device, and it is easy to operate, convenient and time saving, so it is suitable for clinical application.
