To investigate inhibitory effect for oral bacterial proliferation, we divided 12 dogs into 3 groups; scaling alone (C; control group), brushing (B) and application of toothpaste (P). Before scaling (Pre) and at 0 to 8 weeks after scaling (0-8 w), we collected oral bacteria from the dental surface every week and counted them using a bacterial counter. The results demonstrated a significant reduction in the number of oral bacteria for group B relative to Pre and group C, as well as for group P relative to group C at 5-7 w. Consequently, brushing may inhibit an increase in the number of oral bacteria, and toothpaste may be effective at a certain level, although not more than that of brushing.
为研究对口腔细菌增殖的抑制作用，我们将12只狗分为3组：仅进行洗牙（C；对照组）、刷牙（B）和使用牙膏（P）。在洗牙前（Pre）以及洗牙后0至8周（0 - 8周），我们每周从牙齿表面收集口腔细菌，并使用细菌计数器进行计数。结果表明，与洗牙前和C组相比，B组的口腔细菌数量显著减少，并且在5 - 7周时，P组相对于C组的口腔细菌数量也显著减少。因此，刷牙可能会抑制口腔细菌数量的增加，牙膏在一定程度上可能有效，尽管效果不超过刷牙。
