目的评估以蓝牙牙刷和智能手机应用为基础的基于货币激励的口腔卫生干预措施的可行性、可接受性和早期效果。设计一项分层、平行分组、三臂单独随机对照的试点试验。设置两个洛杉矶地区早期学前教育(EHS)站点。36名参加EHS家访计划的参与者在分层和排列区块内随机分配到三组中的一组：等待名单(延迟货币激励)对照组、固定货币激励方案或彩票货币激励方案。干预持续8周。主要结果是a)刷牙表现：平均每周刷牙时蓝牙记录的半天发作次数，以及b)对没有牙科检查的儿童进行2个月的牙科随访。先验的里程碑，刷牙频率增加了20%，为随后的试验确定了干预措施。可行性和可接受性措施也进行了评估，包括父母将蓝牙牙刷同步到智能手机应用程序的频率，以及从数码照片中测量牙菌斑的频率。平均每周刷牙次数超过8周的对照组为3.9次，固定激励组为4.1次，彩票激励组为6.0次。彩票组的刷牙频率比对照组高53%，比固定组高47%。探索性分析显示影响集中在儿童中
AimsTo assess feasibility, acceptability, and early efficacy of monetary incentive-based interventions on fostering oral hygiene in young children measured with a Bluetooth-enabled toothbrush and smartphone application.DesignA stratified, parallel-group, three-arm individually randomized controlled pilot trial.SettingTwo Los Angeles area Early Head Start (EHS) sites.Participants36 parent-child dyads enrolled in an EHS home visit program for 0-3 year olds.InterventionsEligible dyads, within strata and permuted blocks, were randomized in equal allocation to one of three groups: waitlist (delayed monetary incentive) control group, fixed monetary incentive package, or lottery monetary incentive package. The intervention lasted 8 weeks.OutcomesPrimary outcomes were a) toothbrushing performance: mean number of Bluetooth-recorded half-day episodes per week when the child's teeth were brushed, and b) dental visit by the 2-month follow-up among children with no prior dental visit. The a priori milestone of 20% more frequent toothbrushing identified the intervention for a subsequent trial. Feasibility and acceptability measures were also assessed, including frequency of parents syncing the Bluetooth-enabled toothbrush to the smartphone application and plaque measurement from digital photographs.FindingsDigital monitoring of toothbrushing was feasible. Mean number of weekly toothbrushing episodes over 8 weeks was 3.9 in the control group, 4.1 in the fixed incentive group, and 6.0 in the lottery incentive group. The lottery group had 53% more frequent toothbrushing than the control group and 47% more frequent toothbrushing than the fixed group. Exploratory analyses showed effects concentrated among children
