Oral Health Trial Data for 1,156 Adolescents in Hong Kong, 2016-2018

Clinical and survey data from a three-arm, cluster-randomized controlled trial investigating a mobile health intervention for adolescent oral health. The dataset includes 1,156 adolescents aged 12 to 15 years from 12 secondary schools in Hong Kong, with assessments at baseline, 3 months, and 15 months. Data was collected by Lili He and published on figshare in 2026.

Use Cases

• Evaluate intervention effectiveness on oral hygiene practices and sugar intake based on behavioral survey data.
• Analyze changes in clinical outcomes like Visible Plaque Index and DMFT scores over a 15-month period.
• Compare the impact of family-inclusive versus adolescent-only mHealth messaging on health beliefs.
• Model predictors of dental caries and gingivitis prevention from baseline demographic and belief variables.

Strengths

• Data from a randomized controlled trial with 1,156 participants, providing a robust sample size.
• Longitudinal design with measurements at three time points: baseline, 3 months, and 15 months.
• Includes multiple outcome types: clinical indices, self-reported behaviors, and health beliefs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Hong Kong school population.
