Previous studies have suggested that if either sugar-free or sucrose-containing chewing gum is chewed after acidogenic meals or snacks, the plaque pH response to the latter is reduced and the potential for remineralisation of experimental white spot caries lesions is enhanced. This study has compared the effects of both gums on plaque pH (measured by the sampling technique) in 10 subjects who chewed the gums after standard acidogenic challenges (sucrose rinse, cupcake, and fried chicken dinner). The results showed that while both gums can significantly reduce the acid response, sugar-free gum appears more effective.
先前的研究表明，如果在产酸膳食或零食后咀嚼无糖口香糖或含蔗糖口香糖，菌斑对后者的pH反应会降低，实验性白斑龋损的再矿化潜力会增强。本研究比较了这两种口香糖对10名受试者菌斑pH值（通过采样技术测量）的影响，这些受试者在标准产酸刺激（蔗糖漱口、纸杯蛋糕和炸鸡晚餐）后咀嚼口香糖。结果表明，虽然两种口香糖都能显著降低酸反应，但无糖口香糖似乎更有效。
