The aim of this trial was to test whether the use of a smartphone application (app) connected to a toothbrush improves the oral hygiene compliance of adolescent orthodontic patients.
The study was designed as a multicentre, randomized, controlled clinical trial.
Two academic hospitals.
The study was approved by the ethics committee.
This multicentre randomized controlled trial was conducted on 38 adolescents aged 12-18 years with full-fixed orthodontic appliances. Participants were randomly assigned either to a test group that used an interactive oscillating/rotating electric toothbrush connected to a brushing aid app or to a control group that used an oscillating/rotating electric toothbrush alone. At baseline, all patients received verbal and written oral hygiene instructions.
Data collection was performed at T1 (baseline), T2 (6 weeks), T3 (12 weeks) and T4 (18 weeks-end of the study). At each time point, the plaque index (PI), gingival index (GI) and white spot lesion (WSL) score were recorded. Several app-related parameters were evaluated. Patient-related outcome measures were investigated in the test group.
Test and control groups were similar at baseline except for WSL score. Between T1 and T4, PI and GI decreased significantly in both groups but evolutions were globally similar in both groups. Interestingly, at T3 (12 weeks), the PI was significantly lower in the app group than in the control group (P = 0.014). Data showed a marked decline in the use of the app over time in the test group.
This trial, conducted over 18 weeks in two academic hospitals, showed no significant effect of the use of the app in promoting oral hygiene.

本试验旨在测试使用与牙刷相连的智能手机应用程序（app）是否能提高青少年正畸患者的口腔卫生依从性。
本研究设计为一项多中心、随机、对照临床试验。
两家学术医院。
本研究经伦理委员会批准。
这项多中心随机对照试验在38名年龄在12 - 18岁、佩戴全固定正畸矫治器的青少年中进行。参与者被随机分为试验组和对照组，试验组使用与刷牙辅助app相连的交互式振动/旋转电动牙刷，对照组仅使用振动/旋转电动牙刷。在基线时，所有患者均接受了口头和书面的口腔卫生指导。
在T1（基线）、T2（6周）、T3（12周）和T4（18周 - 研究结束）进行数据收集。在每个时间点，记录菌斑指数（PI）、牙龈指数（GI）和白斑病变（WSL）评分。评估了几个与app相关的参数。在试验组中调查了与患者相关的结果指标。
除WSL评分外，试验组和对照组在基线时相似。在T1和T4之间，两组的PI和GI均显著下降，但两组的变化总体相似。有趣的是，在T3（12周）时，app组的PI显著低于对照组（P = 0.014）。数据显示试验组中app的使用随时间明显下降。
在两家学术医院进行的为期18周的这项试验表明，使用该app对促进口腔卫生没有显著效果。
