摘　　要：本文对１０名年龄５２～７０岁中老年人根部菌斑的产酸情况进行分析．结果发现根部菌斑和咬合面菌斑的产酸力相同，产生的有机酸种类也相同，不同有机酸的浓度则有差别，根部菌斑产生的乙酸量明显高于咬合面菌斑．The authors analysed the acid production of root plaque in 10 elders aged 52￣ 70. The results showed that the acidogenicity of root plaque was the same as occlusal plaque. The types of acids produced by the two plaques were also similar. The concentrations of acids were different. Root plaque produced more acetic acids than occlusal plaque.
