对三种含漱剂含漱前后唾液中细菌量进行测定，结果显示：洗必太和护齿剂含漱后５ｍｉｎ、３０ｍｉｎ、６０ｍｉｎ、１８０ｍｉｎ细菌量均有明显降低（ｐ＜０．０５），而对照组蒸馏水含漱后各时间段细菌量减少不明显（ｐ＞０．０５）；且洗必太组和护齿剂组合漱后各时间段细菌降低量相似（ｐ＞０．０５），同时，两组间比较５ｍｉｎ～５ｍｉｎ、３０ｍｉｎ～３０ｍｉｎ、６０ｍｉｎ～６０ｍｉｎ细菌降低量也相似（ｐ＞０．０５），提示护齿含漱剂不失为一种对龋病、牙周病、冠周炎都有较好抑菌作用的牙科保健用品。 The amount of bacteria in the saliva before and after the gargle was measured. The results showed that the bacterial counts of saliva at three kinds of gargle before and after rinsing were significantly lower (P <0.05) at 5 min, 30 min, 60 min and 180 min after gargle, However, there was no significant reduction of bacteria in the control group after rinsing with distilled water for a long time (p> 0.05) At the same time, the reduction of bacteria in 5min ~ 5min, 30min ~ 30min, 60min ~ 60min was also similar between the two groups (p> 0.05), suggesting that mouthwash gargle is a kind of caries, periodontal disease, pericoronitis Have better antibacterial effect of dental health products.
