不同治疗方法对牙龈炎患者口气改善的效果评价

A study on evaluation of two different methods used to improve oral malodor in gingivitis patients

目的 探讨不同治疗方法对牙龈炎患者口气改善的效果。方法 按口臭程度分层,随机抽取牙龈炎患者60例,随机分为3组:洁牙组、漱口组、对照组。洁牙组进行超声波全口龈上洁治,漱口组使用龙掌口含液含漱1周。口气测量仪测定治疗前、治疗结束后1周、2周、1月的口气值,结果进行统计学分析。结果 实验前三组口气值无显著性差异。1周后,洁牙组与漱口水组口气值均降低,与对照组有显著性差异;2周后,漱口水组口气值回升,与对照组无显著性差异;1月后,洁牙组口气值亦有回升,但与其他两组相比,仍有显著性差异。结论传统的洁治术对牙龈炎患者口气的改善是有效的。

Objective To evaluate the effects of two different methods used to improve oral malodor in gingivitis patients. Methods 60 patients of gingivitis were selected and randomly divided into 3 groups, ultrasonic scaling group, mouthrinse group and control group. Oral malodor was evaluated at baseline (pre-therapy) and at 1, 2 weeks and 1 month post - therapy by Halimeter. Results 1 week after therapy, the ppb of VSC in both experimental groups were descended. 2 weeks after therapy, patients' ppb of VSC in mouthrinse group were risen and had no difference from the control group. 1 month later, subjects ppb values in ultrasonic scaling group rise too, but still significantly different from the other two groups. Conclusion Ultrasonic scaling is effective to improve the oral malodor in gingivitis patients.
