BACKGROUND To evaluate the efficacy of a newly developed electric toothbrush in reducing dental plaque via a quantitative light-induced fluorescence-digital (QLF-D)-applied visualisation system in the brush head. METHODS Participants included 20 adults aged 19 to 28 years. Participants were randomly assigned either (i) an electric toothbrush with a monitor to visualise red-fluorescent dental plaque via a camera built into the brush head (monitor usage group, n = 10) or (ii) an electric toothbrush without a monitor (monitor-non-use group, n = 10). The amount of dental plaque was assessed by personal hygiene performance (PHP) at baseline and 1 week later. RESULTS In the monitor-usage group, PHP score was significantly lower at the 1-week follow-up than at baseline (6 vs 16; range, 0-12 vs 13-21; P = 0.029). This change was not observed in the monitor-non-use group (14 vs 13; range, 6-21 vs 2-26; P = 0.778). After 1 week, the change in PHP scores in the monitor usage group was significantly greater than that in the monitor non-use group (- 10 vs 0; range, - 21 to 9 vs - 8 to 16; P = 0.021). CONCLUSIONS Our results clearly demonstrate that brushing teeth while looking at a monitor that depicts red-autofluorescent dental plaque via application of QLF-D improved the efficacy of dental-plaque removal relative to brushing teeth without a monitor.

使用和不使用QLF-D应用牙菌斑显像后使用电动牙刷后牙菌斑减少的比较:一项为期1周的随机对照试验。

背景技术为了评估新开发的电动牙刷通过在刷头中应用定量光诱导的荧光数字(QLF-D)可视化系统来减少牙菌斑的功效。方法参与者包括20名19至28岁的成年人。随机分配参与者(i)带有监视器的电动牙刷,以通过刷头中内置的摄像头可视化红色荧光牙菌斑(监视器使用组,n = 10),或(ii)不带监视器的电动牙刷(监视器) -不使用组,n = 10)。在基线和1周后通过个人卫生表现(PHP)评估牙菌斑的量。结果在监测使用组中,在1周的随访中PHP评分明显低于基线(6 vs 16;范围:0-12 vs 13-21; P = 0.029)。在不使用监控器的组中未观察到这种变化(14 vs 13;范围6-21 vs 2-26; P = 0.778)。1周后,监控程序使用组中PHP得分的变化明显大于不使用监控器组中的PHP得分(-10 vs 0;范围-21至9 vs-8至16; P = 0.021)。结论我们的结果清楚地表明,与不使用监护仪的刷牙相比,通过使用QLF-D观察描绘红色自发荧光性牙菌斑的监护仪时刷牙改善了去除牙菌斑的功效。试用注册号:UMIN000033699。登记名称:有关口腔护理新设计对牙菌斑清除效果的研究。注册日期:2018年9月8日。注册状态:已完成。监视器使用情况组中PHP得分的变化明显大于监视器不使用组中的PHP得分变化(-10 vs 0;范围-21至9 vs-8至16; P = 0.021)。结论我们的结果清楚地表明,与不使用监护仪的刷牙相比,通过使用QLF-D观察描绘红色自发荧光性牙菌斑的监护仪时刷牙改善了去除牙菌斑的功效。试用注册号:UMIN000033699。登记名称:有关口腔护理新设计对牙菌斑清除效果的研究。注册日期:2018年9月8日。注册状态:已完成。监视器使用情况组中PHP得分的变化明显大于监视器不使用组中的PHP得分变化(-10 vs 0;范围-21至9 vs-8-16; P = 0.021)。结论我们的结果清楚地表明,与不使用监护仪的刷牙相比,通过使用QLF-D观察描绘红色自发荧光性牙菌斑的监护仪时刷牙改善了去除牙菌斑的功效。试用注册号:UMIN000033699。登记名称:有关口腔护理新设计对牙菌斑清除效果的研究。注册日期:2018年9月8日。注册状态:已完成。结论我们的结果清楚地表明,与不使用监护仪的刷牙相比,通过使用QLF-D观察描绘红色自发荧光性牙菌斑的监护仪时刷牙改善了去除牙菌斑的功效。试用注册号:UMIN000033699。登记名称:口腔护理新装置对牙菌斑清除效果的研究。注册日期:2018年9月8日。注册状态:已完成。结论我们的结果清楚地表明,与不使用监护仪的刷牙相比,通过使用QLF-D观察描绘红色自发荧光性牙菌斑的监护仪时刷牙改善了去除牙菌斑的功效。试用注册号:UMIN000033699。登记名称:有关口腔护理新设计对牙菌斑清除效果的研究。注册日期:2018年9月8日。注册状态:已完成。
