A variety of sealants have been explored or developed (168), with many people having one or more applications of a sealant. Sealants are vital for promotion of adhesion, which significantly reduces caries formation (169-177). Pit and fissure sealants are covered under the American Dental Association (ADA) Acceptance Program. These materials are used to seal high caries-susceptible pits and fissures of the deciduous and permanent molars, and also to seal microspaces between the tooth and restorative materials, enabling these materials to adhere firmly both to prepared cavity walls and to other restoratives. They provide dental pulp protection and protection from secondary caries formation. 

Since then, uses have shifted toward civilian applications. Polysulfides have unusually good resistance to solvents and to the environment and they have good low temperature properties. They are particularly useful in a variety of sealant applications. For example, the outstanding resistance of polysulfides to petroleum products has made them the standard sealant for virtually all aircraft integral fuel tanks and bodies. Another important application is in insulating glass window sealants. Sealants based on liquid polysulfides have had an excellent record since the 1950s and are the worldwide market leader in these applications.
