What is the definition or description of: fissure sealant?

A preventive adjunct: Pit and fissure sealants are preventive agents (typically resins) placed on the grooves of teeth to help prevent food from getting trapped and causing dental decay. This very easy procedure is an important part of dentistry's efforts to help eliminate dental disease.

Protective coating: Posterior permanent teeth have deep grooves and crevices on the chewing surface. This is the most common area to get a cavity on these teeth. Dental sealants are a composite material that is flowed into these areas to make them "shallow valleys" so food and bacteria can't get stuck in these grooves, thus making it harder to get a cavity. Sealants are cost effective and easy for the patient.

Cavity Prevention: It is a material that is placed on the surface of a tooth to help decrease the risk of developing a cavity.
