目的 观察低功率微波治疗边缘性牙周炎的疗效。方法 采用电脑微波治疗仪 ,用适当的牙周辐射器 ,输出功率 1 7W ,对 4 2例边缘性牙周炎 60患牙进行接触性辐射治疗。每日 1次 ,2 0分钟 ,1 0天后评定疗效。分析治疗前后牙周袋 (或牙龈沟 )内细菌种类分布情况。同时以口服灭滴灵治疗 4 0例 60牙为对照组。比较两组的疗效。结果 观察组显效率为 58.3 % ,对照组为 4 0 .0 % ,观察组显著优于对照组 (P值 <0 .0 5)。两组间的总有效率无显著性差异。结论 低功率微波牙周辐射器治疗边缘性牙周炎 ,疗效显著 ,无痛苦 ,患者易接受。
Objective To observe the curative effect of low power microwave on marginal periodontitis. Methods A computerized microwave therapeutic apparatus was used to treat 42 teeth with marginal periodontitis with contact radiance using an appropriate periodontal radiator with an output of 17 W. 1 day, 20 minutes, 10 days after the assessment of efficacy. Analysis before and after treatment periodontal pocket (or gingival sulcus) within the bacterial species distribution. Oral metronidazole oral treatment of 40 cases of 60 teeth as the control group. Compare the curative effect of two groups. Results The effective rate was 58.3% in the observation group and 40.0% in the control group. The observation group was significantly better than the control group (P <0.05). There was no significant difference in the total effective rate between the two groups. Conclusion Low-power microwave periodontal radiosurgery for the treatment of marginal periodontitis has significant curative effect and no pain, and the patients are easy to accept.
