Digital vs. Parent Modeled Toothbrushing

United States112 participantsStarted 2026-01-05

Plain-language summary

This prospective randomized controlled trial will aim to evaluate the effectiveness of two methods of delivering oral hygiene instruction to children aged 3 - 6 years: parent-modeled toothbrushing (control) and the MoodBrush digital application (experimental). The primary endpoint is the change in plaque index scores before and after brushing, measured on 12 tooth surfaces using the Silness and Loe Plaque Index. The study rationale is based in the need to identify efficient and engaging strategies to improve pediatric oral hygiene. The expected outcome is that both groups will demonstrate significant reductions in plaque scores, with children using MoodBrush achieving similar, if not greater improvements in plaque index scores. Follow-up includes an immediate post-brushing assessment at the dental visit, with intrarater reliability checks to ensure measurement consistency. Statistical analyses will include paired t-tests to evaluate pre-post changes within groups and two-sample t-tests to compare differences between groups, with significance set at p \< 0.05. A sample size of 112 participants provides 80% power to detect a mean difference of 0.30 in plaque index score reduction.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
