What this trial studies

This study evaluates the CATCH Healthy Smiles program, a school-based behavioral intervention aimed at reducing dental caries risk among kindergarten to 2nd grade children from low-income, ethnically diverse backgrounds. The program will be implemented in selected schools, with one group receiving the intervention and another serving as a control. The study will assess the impact of the program on children's behavioral, psychosocial, and environmental outcomes, as well as how these factors influence caries risk reduction. Data will be collected to compare outcomes between the intervention and control groups.

Who should consider this trial

Good fit: Ideal candidates for this study are kindergarten children enrolled in schools with a high percentage of students participating in free or reduced lunch programs.

Not a fit: Children with congenital dental conditions or special dental needs may not benefit from this intervention.

Why it matters

Potential benefit: If successful, this program could significantly reduce dental caries in young children, leading to improved oral health and overall well-being.

How similar studies have performed: Previous studies have shown success with school-based oral health interventions, indicating potential for positive outcomes with this approach.
