1. The use of adhesive sealants: Adhesive sealants are thin, plastic coatings applied to the chewing surfaces of the back teeth. They fill in the grooves and depressions, creating a smooth surface that is easier to clean. Sealants act as a barrier, preventing food and bacteria from lodging in these areas and thus reducing the risk of tooth decay. This is considered the best preventive measure because it directly addresses the anatomical vulnerability of the teeth and can be applied quickly and painlessly.

2. Topical fluoride application: While topical fluoride is beneficial in preventing dental cavities, it is not as effective as sealants in preventing pit and fissure caries. Fluoride helps to strengthen the enamel and makes it more resistant to acid attacks from plaque bacteria. However, because the pits and fissures are already deep and narrow, fluoride may not always reach these areas effectively. Sealants, on the other hand, provide a physical barrier that fluoride cannot always penetrate.
