In this study, scaling, polishing and daily tooth brushing were performed in 20 beagle dogs, and the number of oral bacteria was determined using a bacterial counter. The dogs were randomized into the scaling (S), scaling + polishing (SP), scaling + tooth daily brushing (SB) and scaling + polishing + tooth daily brushing (SPB) groups. Samples were collected from the buccal surface of the maxillary fourth premolars of the dogs immediately after scaling and every week thereafter from weeks 1 to 8. Throughout the study, the number of bacteria was significantly lower in the SB and SPB groups compared with the S group. The findings suggest that daily tooth brushing inhibited oral bacterial growth in the dogs.
在本研究中，对20只比格犬进行了洗牙、牙齿抛光和每日刷牙，并使用细菌计数器测定口腔细菌数量。这些犬被随机分为洗牙组（S）、洗牙+抛光组（SP）、洗牙+每日刷牙组（SB）和洗牙+抛光+每日刷牙组（SPB）。在洗牙后立即从犬上颌第四前磨牙的颊面采集样本，此后在第1至8周每周采集一次。在整个研究过程中，SB组和SPB组的细菌数量明显低于S组。研究结果表明，每日刷牙可抑制犬口腔细菌的生长。
