Saliva contains minerals that maintain the integrity of the enamel surface and thus is the most important caries preventive agent. Increased saliva, tooth enamel protection by high calcium and phosphate ions at the tooth surface. The first film layer of plaque, the film is set in the saliva, as well as selective membrane transfer between saliva and mineral-melt interface controls.
As e-age it becomes more difficult. On the enamel surface is changing a continuous circulation of mineral.
The longer melting, these saliva-mediated natural process is exposed, the more resistant it is left to decay. After 20 years of dental enamel was remineralized and the organic material it contains is initially lost. This may explain why the majority of new occur carious lesions in children and adolescents.
The salivary glands Immune System
Saliva contains a number of passive and active immunoproteins that develops to protect the mouth of the resident organisms. Passive immunoproteins include mucins, lysozyme and lactoferrin. They are working to microbial overgrowth clump through interventions in nutrition, weakening cell walls (apotosis) and bacteria are washed away (aggregation) to inhibit. Immunoproteins active, such as s-IgA are produced in the salivary glands of the soft palate. IgG, the most powerful active immunoprotein in the mouth by gin-sulcus. The IgG-works to inhibit the organisms that cause gingivitis. The inflammation causes swelling, which allows gin-sulcus enter the mouth. Gin-IgG in crevicular fluid suppresses the changes in the biofilm that lead to gum inflammation.
