硫化氢分析仪检测抗口臭牙膏功效的研究

Evaluation of effect of an anti-halitosis toothpaste with Halimeter

目的用硫化氢分析仪验证抗口臭牙膏的功效;观察牙膏抗口臭的短期作用。方法选择40名自愿受试者,随机分为用含抗口臭有效成分牙膏的实验组和用无有效成分牙膏的对照组,观察2组刷牙前、后即刻和2h、4h口气值变化。结果2组刷牙后即刻口气值一过性增高,与刷牙前比较有显著性差异(P<0.05);刷牙后2h、4h口气值与刷牙前比较,2组均明显下降,与刷牙前比较有显著性差异(P<0.05);2组口气值刷牙后即刻有显著差异(P<0.05),其余各时段均无显著差异(P>0.05)。结论含与不含抗口臭有效成分牙膏短时间内都有消减口臭作用,但不易区分,应延长观察时间。

Objective To evaluate the effect of an anti-halitosis toothpaste with Halimeter. Methods Forty volunteers were randomly divided into two groups. The volunteers of the test group brushed their teeth with the toothpaste containing effective component, and of control group brushed their teeth with the toothpaste without effective component. The oral chroma of different groups were detected by Halimeter at 0,2 and 4 hours after brushing. Results There was significant change of oral chroma before and after brushing in both groups, but the difference was not significant in oral chroma between the two groups. The oral chroma significantly raised immediately after brushing and decreased at 2 and 4 hours after brushing. Conclusion The toothpast with or without anti-halitosis component can effectively alleviate oral chroma in a short time after tooth brushing. It may need a longer observing time to distinguish the difference in the anti- halitosis effect between the two kinds of toothpast.
