摘要
目的比较两种不同方法对牙体预备后的活髓牙脱敏治疗的临床效果,为其可靠性提供依据。方法 243颗活髓牙分为三组,在局麻下牙体预备后分别涂自酸蚀树脂粘结剂Easy One、锶盐类脱敏剂极固宁或空白对照,制作临时性修复体并粘固。在修复体粘结后及一个月后复诊时,通过视觉模拟评分法评估牙齿敏感程度。结果各组内永久性粘结后及义齿使用一个月后敏感率无明显差异(P>0.05)。锶盐脱敏剂组和树脂粘结剂组敏感率均小于对照组(P<0.01)。锶盐脱敏剂组在最终修复体粘结后敏感率小于树脂粘结剂组(P<0.05),在义齿使用一个月后无明显差异(P>0.05)。结论活髓预备牙表面涂脱敏剂、粘结剂可以减少术后牙髓并发症的发生率,以应用锶盐脱敏剂效果较好。
Objective To evaluate the clinical effects of two different desensitizing bonding system in vitaI teeth after crown preparation. Methods 243 teeth with vital pulp were randomly divided into 3 group, after crown preparation under local anesthesia, each group was coated with resin binder （Easy One）, strontium salts desensitizer （Green Or）or without speciaI treatment respectively. After this all the teeth was bonded with temporary restorations. The coId sensitivity of abutments was tested after cementation of crown and one month later. The visual analogue scales （vas） was used to evaluate the teeth sensitive degree. Results There is not significant differences of the sensitive rate within the each group （P〉0.05）. The sensitive rate of resin binder group and strontium salts desensitizer group is definitely lower than the control group （P〈0.01）. The sensitive rate of strontium salts is definitely lower than the resin binder group after cementation of crown （P〈0.05）, but there was no significant difference between them one month later （P〉0.05）. Conclusion Coating with resin binder and strontium salts desensitizer can reduce the endodontic complications of vitaI teeth after teeth preparation, in addition the application of strontium salt desensitizing agent has better effects.
