目的:观察壳聚糖抗菌膜治疗复发性阿弗他溃疡(RAU)的临床疗效。方法:92例RAU患者随机分成两组,对照组46例给予锡类散喷于溃疡表面,4次/d,;治疗组46例,将壳聚糖抗菌膜喷于溃疡表面,4次/d。结果:治疗组总有效率95.12%,对照组总有效率75.00%,两组疗效比较,差异有统计学意义(P<0.01)。结论:壳聚糖抗菌膜治疗RAU临床疗效好。
Objective: To observe the clinical efficacy of chitosan antibacterial membrane in the treatment of recurrent aphthous ulcer (RAU). Methods: Ninety-two patients with RAU were randomly divided into two groups. 46 patients in the control group were treated with tin spray on the surface of the ulcer 4 times a day. In the treatment group, 46 patients were treated with chitosan antibacterial membrane on the ulcer surface for 4 times a day . Results: The total effective rate was 95.12% in the treatment group and 75.00% in the control group. The difference between the two groups was statistically significant (P <0.01). Conclusion: Chitosan antibacterial membrane is effective in treating RAU.
