Is this trial a fit for you?

Likely a good fit

Ideal candidates are ages 5–13 enrolled in participating schools, with parental consent and child assent, and without exclusions related to active gingival or stomatal conditions or extensive caries requiring more invasive treatment.

Probably not a fit

Children with certain conditions or extensive disease might not experience benefit from the preventive interventions tested and may require alternative care.

What this trial studies

BASICS uses a SMART design to tailor preventive care for dental caries delivered in school settings, embedding dynamic treatment regimes to find the most effective sequence and intensity of interventions. The trial includes interventions such as silver diamine fluoride, glass ionomer sealants, fluoride varnishes, and hygiene support, with a focus on reducing nonresponse and optimizing resource use. Participants are children in participating schools, assessed for response to treatment and guided through adaptive pathways based on their needs. The study emphasizes addressing health disparities by testing personalized approaches in diverse populations and school environments.

Why it matters

Potential benefit: If successful, the adaptive approach could lead to more effective, personalized prevention, reducing new caries and improving oral health for children in school programs.

How similar studies have gone: Previous school-based caries prevention programs show varied success; BASICS aims to improve outcomes by personalizing treatment sequences, which is relatively novel in this setting.
