Pit and fissure sealants, commonly referred to as dental sealants, serve as a preventive measure in dentistry aimed at reducing the risk of tooth decay. Sealants are applied to the occlusal surfaces of teeth, effectively covering the pits and fissures that are prone to decay. This application forms a protective barrier that inhibits caries-causing bacteria from accessing essential nutrients and inflicting damage. Studies indicate that pit-and-fissure sealants are successful in both preventing and halting carious lesions on primary and permanent molars in children and adolescents.
