Abstract：
School children are in a developmental period in which permanent teeth replace primary dentition. It is also a period with a high incidence of gingivitis and caries, which can be improved with adequate tooth brushing. Advances in information technology have led to the development of smart health devices that assist in tooth brushing. We compared the effectiveness of computer-assisted toothbrushing using a toothbrushing instruction (TBI) method called the smart toothbrush and smart mirror (STM) system with that of conventional TBI (verbal instructions) for plaque control in school children.
This randomized controlled clinical trial analyzed and compared the reduction of the modified Quigley-Hein plaque index between the two methods in 42 school children. The participants were randomly assigned to the STM system group (n = 21) or conventional-TBI group (n = 21). The plaque indices were evaluated at baseline, immediately after TBI (day 0), and 1 week and 1 month after TBI.
The STM system and conventional TBI led to an average reduction of 40.50% and 40.57%, respectively, in whole mouth plaque. Reductions in the plaque indices within each tested time period were observed in both groups (P < 0.001), and the mean plaque reduction did not differ between the two groups (P = 0.44).
The present study tested a computer assisted system for TBI, more studies are needed to confirm its usefulness in different objectives. Clinical relevance The computer-assisted STM system may be an alternative of TBI for children.

摘要：
背景：学龄儿童正处于恒牙取代原牙列的发育期。这也是牙龈炎和龋齿发病率高的时期，这可以通过适当的刷牙来改善。信息技术的进步导致了辅助刷牙的智能健康设备的发展。我们比较了使用称为智能牙刷和智能镜子（STM）系统的刷牙指导（TBI）方法与传统TBI（口头指导）对学龄儿童牙菌斑控制的计算机辅助刷牙的有效性。
方法：这项随机对照临床试验分析并比较了两种方法在42名学龄儿童中改良Quigley-Hein菌斑指数的降低。参与者被随机分配到STM系统组（n=21）或常规TBI组（n=21）。在基线时评估斑块指数，TBI后立即（第0天），TBI后1周和1个月。
结果：STM系统和常规TBI平均降低了40.50％和40.57％，分别,在整个口腔斑块上。两组在每个测试时间段内观察到菌斑指数的降低（P<0.001），两组间平均斑块减少无差异(P=0.44).
结论：本研究测试了一种用于TBI的计算机辅助系统，需要更多的研究来证实它在不同目标中的有用性。临床相关性计算机辅助STM系统可能是儿童TBI的替代方案。试验注册ClinicalTrials.gov（NCT04627324）注册2020年11月13日-回顾性注册，https://clinicaltrials.gov/ct2/show/NCT04627324.
