【摘要】：目的探讨脱敏抛光膏对活髓基牙预备后牙本质敏感的临床疗效。方法 43例96颗行冠桥修复的活髓基牙在暂时冠桥及正式冠桥修复前分别用脱敏抛光膏处理,在疼痛游标尺上采用数字化疼痛评判法(VAS),记录处理前后的敏感程度(VAS值),采用SPSS 17.0软件包,对脱敏治疗前后VAS值采用配对t检验进行统计学分析。结果 43例患者(男19例,女24例)96颗活髓基牙,敏感位点分布在唇颊侧占43.37%;应用脱敏抛光膏后72.92%基牙症状即刻完全或部分缓解。暂时冠桥修复前未经脱敏抛光膏处理时的VAS值为(4.43±2.33),脱敏处理后VAS值为(2.23±1.85),处理前后差异有统计学意义(P0.05)。正式冠桥修复前未经脱敏抛光膏处理的VAS值为(4.16±2.21),经脱敏处理后的VAS值为(1.99±1.83),处理前后差异有统计学意义(P0.05)。96颗活髓基牙(男47颗,女49颗),暂时冠桥修复前的VAS平均值分别为3.48±2.65和4.16±2.62,差异无统计学意义(P0.05)。结论活髓基牙预备后唇颊侧最敏感;脱敏抛光膏能够即刻缓解牙体预备后牙本质敏感,值得临床推广;活髓基牙预备后敏感程度与性别无关。
[Abstract]:Objective to investigate the clinical effect of desensitized polishing ointment on dentin sensitivity after preparation of active pulp abutment. Methods Ninety-six active pulp abutments of 43 cases were treated with desensitization and polishing cream before temporary and formal crown and bridge restoration. The sensitivity (VAS) was recorded by digital pain evaluation method (VAS),) on the pain scale before and after treatment. The VAS values before and after desensitization were analyzed by paired t test with SPSS 17.0 software package. Results there were 96 active abutments in 43 patients (19 males and 24 females), the sensitive sites were 43.37 on the lip and buccal side, and 72.92% of the abutment symptoms were completely or partially relieved immediately after the application of desensitized polishing ointment. The VAS was (4.43 卤2.33) and (2.23 卤1.85) before temporary crown and bridge restoration without desensitization and polishing paste, respectively. There was significant difference before and after treatment (P0.05). The VAS value was (4.16 卤2.21) and (1.99 卤1.83), respectively, which were not treated with desensitized polishing paste and (1.99 卤1.83) before and after the formal crown and bridge restoration. The difference was statistically significant (P0.05). 96 living pulp abutment teeth (47 males) were treated. The mean VAS before temporary crown and bridge repair was 3.48 卤2.65 and 4.16 卤2.62, respectively (P0.05). Conclusion the labial and buccal side of living-pulp abutment is the most sensitive, desensitization and polishing ointment can relieve the post-dentine sensitivity immediately, and it is worth popularizing in clinic, and the sensitivity after the preparation of living-pulp abutment is not related to sex.
