A Scalable, Teacher-delivered, School-based Oral Health Intervention for Pakistani Lower Secondary Schoolchildren

This was a pragmatic, two-arm, and parallel-group, superiority cluster-randomized controlled trial with 1:1 allocation of clusters (schools) to either the Smile Smarts-PK intervention arm or the control arm. The trial settings were lower secondary schools (classes 5-8) in the Punjab, Pakistan. Punjab is the most populous province of Pakistan; it has many public and low-cost private schools that serve lower- and middle-income communities.
