目的 探讨康复新液联合西帕依固龈液治疗固定正畸早期牙龈炎的临床疗效。方法 选取2012年1月—2017年5月南阳南石医院口腔科收治的固定正畸早期牙龈炎患者120例进行研究，按随机数字表法将所有患者分为对照组和治疗组，每组各60例。对照组在固定正畸治疗后，分别于晨起后、晚睡前、3餐后含漱西帕依固龈液，5～10 mL/次，含漱3 min。治疗组于含漱西帕依固龈液15 min后含漱康复新液，5～10 mL/次，含漱3 min。以4周为1个疗程，两组患者均治疗6个疗程。观察两组的临床疗效，比较两组的简化口腔卫生指数（OHI-S）、牙龈指数（GI）、牙龈探诊出血（BOP）、菌斑指数（PLI）和并发症情况。结果 治疗后，对照组和治疗组的总有效率分别为80.00%、91.67%，两组比较差异具有统计学意义（P<0.05）。治疗3、6个月后，两组OHI-S、GI、PLI和BOP均升高，同组治疗前后比较差异有统计学意义（P<0.05）；且治疗组这些观察指标均高于对照组，两组比较差异具有统计学意义（P<0.05）。对照组和治疗组的并发症分别为21.67%、8.33%，两组比较差异有统计学意义（P<0.05）。结论 康复新液联合西帕依固龈液治疗固定正畸早期牙龈炎具有较好的临床疗效，可改善牙龈出血、口腔卫生等牙周指标，减少并发症，具有一定的临床推广应用价值。

Objective To investigate the clinical effects of Kangfuxin Liquid combined with Xipayi Mouth Rinse in treatment of early gingivitis in patients with fixed orthodontic treatment. Methods Patients (120 cases) with early gingivitis in fixed orthodontic in Department of Stomatology of Nanshi Hospital of Nanyang from February 2012 to May 2017 were randomly divided into control and treatment groups, and each group had 60 cases. After fixed orthodontic treatment, patients in the control group were gargle administered with Xipayi Mouth Rinse after morning, late bedtime, and after 3 meals, 5-10 mg/time, rinse for 3 minutes. After gargle of Xipayi Mouth Rinse for 15 min, patients in the treatment group were gargle administered with Kangfuxin Liquid on the basis of the control group, 5-10 mg/time, rinse for 3 minutes. With 4 weeks as 1 course, patients in two groups were treated for 6 courses. After treatment, the clinical efficacies were evaluated, and OHI-S, GI, BOP, PLI, and complication in two groups were compared. Results After treatment, the clinical efficacies in the control and treatment groups were 80.00% and 91.67%, respectively, and there was difference between two groups (P < 0.05). After treatment for 3 and 6 months, OHI-S, GI, BOP, and PLI in two groups were increased, and the difference was statistically significant in the same group (P < 0.05). And the observational indexes in the treatment group were significantly higher than those in the control group, with significant difference between two groups (P < 0.05). The incidence of complications in the control and treatment groups were 21.67% and 8.33%, respectively, and there was difference between two groups (P < 0.05). Conclusion Kangfuxin Liquid combined with Xipayi Mouth Rinse has clinical curative effect in treatment of early gingivitis in patients with fixed orthodontic treatment, can improve periodontal indexes including gingival bleeding and oral hygiene, reduce complications, which has a certain clinical application value.
