Study Design

Allocation randomized
Intervention model parallel assignment
Primary purpose treatment
Masking no masking
All 'sealable' permanent molars will be sealed: Occlusal fissures and where appropriate, buccal pits (on lower molars) and palatal pits (on upper molars) will be sealed. If patient compliance is adequate, a resin based sealant will be used as the first choice material. The tooth is thoroughly cleaned, prepared with a special solution, and dried. The liquid sealant is then applied and allowed to set hard.
