蜂胶口胶防龋作用初步研究

Preliminary study of propolis on caries

目的 通过蜂胶口胶对变形链球菌、牙菌斑及唾液 ｐＨ值的影响，初步探讨蜂胶口胶的防龋作用与机理。方法 选择３～４岁儿童，分别在使用蜂胶。胶前后进行口腔变形链球菌的半定量测定，牙菌斑指数及唾液ｐＨ值的检测。结果 观察组使用蜂胶口胶后变形链球菌数量显著减少，牙菌斑指数降低，唾液ｐＨ值高于对照组。结论 蜂胶口胶抑制变形链球菌的生长繁殖，影响牙菌斑的形成，并升高唾液ｐＨ值，在龋病的预防上有开发价值。

The preventive effect and mechanism of propolis on caries were studied. Methods Before and after chewing propolis gum, SM bacteria, plague index and salivary pH were determined in 3 ~ 4 years old children. Results Propolis gum significantly reduced the plaque index, the numbers of SM, and raised the salivary pH. Conclusion Propolis gum can depress the growth of SM and development of plaque, increase the pH value in saliva, and is usefull in preventing caries.
