If, for example, the adhesion to the enamel is far greater than the bond to the dentin, the stronger force at the enamel interface will tend to pull the composite away from the dentinal margin during the polymerization process, weakening the dentin interface. Although dentin is a wet substance, the constituents of saliva and blood create an environment that can destroy dentin bonding. In addition, bioactive materials that release calcium, phosphates, and other therapeutic ions that can provide a favorable environment for the remineralization of acid demineralized dentin may also play an important role in the future of adhesive and restorative dentistry. - Evolution of dental adhesives.
