Genes Involved in Saliva Formation and Composition and Their Impact on Caries Susceptibility and Erosive Tooth Wear.

Saliva interfaces with all oral tissues and modulates the development of dental caries or erosive tooth wear. Its mechanical function of coating all surfaces combined with the components in saliva modulates individual susceptibility to dental caries or erosive tooth wear. The effort to associate genes known to regulate saliva roles with dental caries experience has been carefully reviewed in the literature, and this chapter reflects on these studies from their conception standpoint, highlighting limitations in design, and adds a review to the work on erosive tooth wear.
