【摘要】：目的:比较两步法酸蚀冲洗型粘接剂与一步法自酸蚀粘接剂用于楔状缺损直接修复的临床效果。方法:选择口内同时存在两颗楔状缺损患牙的患者50人,随机采用两步法酸蚀冲洗型粘接剂(α组)或一步法自酸蚀粘接剂(β组)粘接并用复合树脂修复缺损。所有操作由一位医师按照标准临床步骤完成,再由另外一位检查者根据改良USPHS(United States Public Health Service)评价标准在术后1周(基线)、6个月及18个月对修复体固位、边缘适合性、边缘着色、继发龋、术后敏感进行评价,采用卡方检验对复查结果进行统计分析。结果:基线两组各纳入50例修复体;6个月复查48位患者,α组与β组分别有两例修复体脱落,18个月复查44位患者,α组与β组分别累计有4例和6例修复体脱落,固位率分别为α组90.0%,β组86.4%。α和β组分别有3例和5例修复体边缘适合性评价为B,两组分别有2例和3例修复体边缘着色评价为B,所有复查修复体均未观察到继发龋及术后敏感的情况。卡方检验显示,两组之间所有评价项目差异均无统计学意义(P0.05)。结论:一步法自酸蚀粘接剂与两步法酸蚀冲洗型粘接剂在观察时间内表现相近,能够满足临床要求,远期效果仍需进一步观察。
[Abstract]:Objective: to compare the clinical effects of two-step etching-flushing adhesive and one-step self-etching adhesive in the direct repair of wedge-shaped defects. Methods: a total of 50 patients with two wedge-shaped defects in the mouth were randomly divided into two groups. The defect was repaired with two-step acid etching flushing adhesive (伪 group) or one-step self-etching adhesive (尾 group) with composite resin. All operations were performed by one physician in accordance with the standard clinical procedures, and then by another examiner at 1 week after surgery (baseline, 6 and 18 months) according to the modified USPHS(United States Public Health Service) evaluation criteria. Secondary caries, postoperative sensitivity evaluation, chi-square test was used to review the results of statistical analysis. Results: 50 prostheses were included in each group, 48 patients were examined in 6 months, two patients in 伪 group and four patients in 尾 group, 44 patients in 18 months, 4 cases in 伪 group and 6 cases in 尾 group, respectively, and 4 cases in 伪 group and 6 cases in 尾 group respectively. The retention rate was 90.0 in 伪 group and 86.4 in 尾 group, respectively. In 伪 and 尾 groups, 3 cases and 5 cases of restoration edge suitability were evaluated as B, and 2 cases and 3 cases of restoration edge coloration were evaluated as B, respectively. Secondary caries were not observed in all reexamined restorations. And postoperative sensitivities. Chi-square test showed that there was no significant difference in all evaluation items between the two groups (P 0.05). Conclusion: One-step self-etching adhesive and two-step acid-etching flushing adhesive are similar in observation time and can meet the clinical requirements, and the long-term effects need to be further observed.
