Monetary incentives for improving smartphone-measured oral hygiene behaviors in young children: A randomized pilot trial.

<h4>Aims</h4>To 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.<h4>Design</h4>A stratified, parallel-group, thr...

The intervention lasted 8 weeks.<h4>Outcomes</h4>Primary 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.<h4>Findings</h4>Digital 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 ≤24 months. Follow-up dental visit attendance was similar across groups. iPhone 7 more reliably captured evaluable images than Photomed Cannon G16.<h4>Conclusions</h4>Trial protocol and outcome measures were deemed feasible and acceptable. Results informed the study protocol for a fully powered trial of lottery incentives versus a delayed control using the smart toothbrush and remote digital incentive program administration.<h4>Trial registration</h4>ClinicalTrials.gov identifier NCT03862443.Justin S WhiteFrancisco Ramos-GomezJenny X LiuBonnie JueTracy L FinlaysonJeremiah R GarzaAlexandra H CrawfordSarit HelmanWilliam SantoJing ChengJames G KahnStuart A GanskyPublic Library of Science (PLoS)articleMedicineRScienceQENPLoS ONE, Vol 15, Iss 7, p e0236692 (2020)
