Summary

This trial tests whether a WhatsApp-based program called SmileConnect can help parents improve their children's oral health. The program sends educational messages, reminders, videos, and fun brushing activities to parents of primary school children aged 5-12. Researchers will compare the oral hygiene of children whose families receive the program against those who get usual care, to see if digital support can lead to better brushing habits and fewer cavities.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a WhatsApp-based family engagement programme called SmileConnect that delivers oral health education, behaviour-change messages, reminders, videos, quizzes, and parent-child brushing activities
What this could lead to
If it works, this could point toward a scalable, low-cost way to improve children's oral health in low- and middle-income countries.
What could go wrong
This is a behavioural intervention, so results may vary widely by family engagement and cultural context. The trial is early-stage and may not show lasting improvements.

An estimate. Start dates often move.

Expected to finish

May 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Parent or primary caregiver of a child enrolled in a participating primary school. 2. Child aged 5-12 years (or the age range specified by the study). 3. Parent or caregiver owns or has regular access to a smartphone with an active WhatsApp account. 4. Parent or caregiver is able to read and understand the study language(s) (e.g., Urdu and/or English). 5. Parent or caregiver is willing to receive WhatsApp messages throughout the intervention period. 6. Parent or caregiver provides written informed consent; child provides assent where age-appropriate. Exclusion Criteria: 1. Parent or caregiver declines or withdraws informed consent. 2. Child has a medical, developmental, or cognitive condition that would prevent participation in routine oral health assessments or toothbrushing activities, as determined by the investigators. 3. Child is currently participating in another oral health intervention or clinical trial that could influence the study outcomes. 4. Parent or caregiver plans to relocate or anticipates being unavailable during the study follow-up period. 5. Child requires urgent medical or dental care that would preclude participation, as judged by the study dentist (children identified with urgent dental needs during screening will be referred for appropriate care and their eligibility will be determined by the study protocol). 6. More than one eligible child from the same household is enrolled; in such cases, one child will be selected according to the study protocol to maintain independence of observations.
