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.

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.
