定期牙周洁治对固定正畸治疗中牙周健康的影响

目的:观察洁治和使用雅皓乳膏对正畸患者牙周健康状况的影响。方法:选择全身及牙周健康因错牙合畸形需固定矫治的患者48例(男28例,女20例),随机分为对照组和治疗组(洁治及用雅皓乳膏刷牙)2组。治疗组用雅皓乳膏(主要成分是丁香酚和硼砂)每天早晚各刷牙1次,每次不少于3m in。对照组用普通市售牙膏。于治疗前和治疗后3个月检测牙龈指数(GI)、菌斑指数(PLI)和龈沟出血指数(SBI),比较检测指标在治疗前后的变化,数据以t检验和χ2检验进行统计学处理。结果:治疗前2组间无显著差异(P>0.5),而治疗后存在显著性差异(P<0.01),表明洁治和用雅皓乳膏刷牙在固定矫治过程中能有效降低牙龈炎的发生率。结论:治疗组患者在矫治过程中牙周指数升幅和牙龈炎发生率明显低于对照组,说明牙周洁治和用雅皓乳膏刷牙能降低固定矫治治疗导致的牙周组织的不良反应。

The effect of regular scaling on periodontal health in fixed orthodontic treatment

PURPOSE: The purpose of this study was to investigate the effect of scaling and teeth brushing with YAHAO toothpaste (eugenol and borax cream)on periodontal health in fixed orthodontic treatment. METHODS: 48 patients who needed fixed orthodontics were chosen to enroll a single-blind randomized study. The patients were randomly divided into two groups: the control group and the treatment group. Patients in the treatment group were treated with scaling and teeth brushing with YAHAO toothpaste. The changes of GI, PLI and SBI were recorded at the beginning of the treatment and after 3 months. SPSS 10.0 software package was used for Student's t test and Chi-square test. RESULTS: There was no significant difference in the periodontal indexes between the two groups before treatment. But there was a statistically significant difference in the incidence of gingivitis(P<0.01) between the two groups after treatment. CONCLUSION: The increase in the periodontal index and the rate of gingivitis in the treatment group were statistically significantly lower than that in the control group, which means that using scaling and teeth brushing with YAHAO toothpaste can effectively reduce the rate of gingivitis.
