The multiple functions of saliva play a significant role in the prevention of dental caries.
Chewing gum is known to stimulate salivary flow, and the results of studies of the role of stimulated saliva in the oral clearance of food particles, neutralization of dental plaque acids and reduction of the incidence of dental caries have been reported. The author reviews the results of these clinical caries trials.
Seven clinical trials have evaluated the impact of chewing gum on caries incidence. These studies have shown that chewing sugar-free gum after meals results in a significant decrease in the incidence of dental caries and that the benefit is due to stimulating salivary flow rather than any chewing gum ingredient.
Stimulating salivary flow through the chewing of sugar-free gum after meals has been shown to reduce the incidence of dental caries.
Practical measures for stimulating salivary flow after meals or snacks should be considered in caries prevention programs.
唾液的多种功能在预防龋齿方面发挥着重要作用。
已知嚼口香糖能刺激唾液分泌，并且关于刺激唾液在口腔清除食物颗粒、中和牙菌斑酸以及降低龋齿发病率方面作用的研究结果已有报道。作者回顾了这些临床龋齿试验的结果。
七项临床试验评估了口香糖对龋齿发病率的影响。这些研究表明，饭后嚼无糖口香糖会使龋齿发病率显著降低，且这种益处归因于刺激唾液分泌而非口香糖的任何成分。
已证明饭后嚼无糖口香糖刺激唾液分泌可降低龋齿发病率。
在龋齿预防项目中应考虑采取饭后或吃零食后刺激唾液分泌的实际措施。
