摘要： 目的： 通过比较声波震动牙刷和手动牙刷对儿童刷牙效率的影响及安全性，为儿童口腔卫生指导及牙病预防提供理论依据。方法： 纳入健康儿童180例，3~6岁、6~9岁各90例。2个年龄组受试者随机分为声波震动牙刷（SFK）组及手动牙刷（MTB）组。在28天试验期内，按分组使用声波震动牙刷或者手动牙刷进行菌斑控制。于试验基线期、第7天及第28天（D0、D7、D28）对口腔卫生相关指数进行检查、记录菌斑指数（Rustogi modified Navy plaque index，RMNPI），采用R软件进行统计学分析。结果： MTB和SFK均能去除部分牙菌斑，3~6岁的SFK组在D0、D7、D28天的菌斑清除率（17.09%±14.4%、27.14%±11.4%、33.52%±18.3%）均显著高于相应MTB组（11.86%±9.7%、11.83%±9.1%，13.73%±11.0%）（P<0.05）；6~9岁的SFK组在D0、D7、D28天的菌斑清除率（20.05%±10.52%、22.76%±13.46%、22.31%±9.74%）均显著高于相应MTB组（9.15%±7.07%、7.26%±6.81%，11.54%±8.27%）（P<0.05）。进一步分析发现，3~6岁SFK组随访牙菌斑指数逐渐降低（P<0.05），声波震动牙刷具有良好的儿童使用依从性及安全性。结论： 声波震动牙刷可有效去除儿童牙菌斑，长期使用可有效控制儿童牙菌斑，提高儿童口腔卫生质量，是一种可推广的日常儿童牙菌斑控制手段。

Abstract: PURPOSE: To provide theoretical basis for children's oral health instruction and children's dental prophylaxis by comparing the plaque control efficacy and safety of Sonicare and manual toothbrush in 3-9 years old children. METHODS: One hundred and eighty healthy children were included in this study and were divided into 2 groups with 90 children in each group: aged 3-6 years and 6-9 years respectively. In each group, the subjects were randomly instructed to use either Sonicare for kids (SFK) or manual tooth brush (MTB). During a 28-day clinical trial period, oral hygiene was examined and plaque index（Rustogi modified Navy plaque index，RMNPI） was recorded at baseline, and at visits on the 7th and the 28th day (D0, D7, D28). The data were analyzed by R software. RESULTS: Both MTB and SFK could remove a certain amount of dental plaque. In the group of 3-6 years old children, the plaque reduction rates of children using SFK were 17.09%±14.4%(D0), 27.14%±11.4%(D7), 33.52%±18.3%(D28), respectively, which were significantly higher than that of children using MTB [11.86%±9.7%(D0), 11.83%±9.1%(D7), 13.73%±11.0%（D28）] (P<0.05). Similarly, in the group of 6-9 years old children, the plaque reduction rates of children using SFK were 20.05%±10.52%(D0), 22.76%±13.46%(D7), 22.31%±9.74% (D28), which were significantly higher than that of children using MTB [9.15%±7.07%(D0), 7.26%±6.81%(D7), 11.54%±8.27%（D28）] (P<0.05). Further analysis revealed that the plaque index was decreased gradually in 3-6 years old children using SFK after 3 months of follow-up (P<0.05). In addition, there was better compliance and safety in children using SFK. CONCLUSIONS: Sonicare can remove plaque efficiently, and can control plaque and improve oral hygiene quality effectively in children in a long period, which implies that the application of Sonicare is worthy of promoting to control dental plaque in children.
