Sealants are most commonly placed on which surfaces of molars and premolars?

Explanation:
Sealants protect the chewing surfaces where pits and fissures commonly harbor decay. Molars and premolars have deep grooves on their occlusal (biting) surfaces that trap plaque and food, making caries likely if left exposed. Applying a sealant fills and seals those grooves, creating a smooth barrier that prevents bacteria and food from penetrating the enamel. That’s why sealants are placed on the occlusal surfaces of these teeth. The other surfaces—buccal or lingual—don’t typically have the same deep pits, and the incisal edges aren’t present on molars and premolars, so they’re not the usual targets for sealants.
