Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The four caries prevention methods are: resin fissure sealant, atraumatic restorative treatment (ART) sealant, sodium fluoride varnish, and silver diamine fluoride (SDF) solution.
The specific study objectives are:
1. to describe longitudinally the clinical outcomes of using the above four methods to prevent dental caries in the pits and fissures of permanent first molars in school children,
2. to describe the cost of using the above four methods to prevent dental caries in an outreaching dental care programme in China, and
3. to compare the cost-effectiveness of the above four caries prevention methods.
