Saliva acts to dilute and neutralise the acid which causes demineralisation and is an important natural defence against caries aside from buffering plaque acids and halting the demineralisation of enamel, saliva provides a reservoir of minerals adjacent to the enamel from which it can remineralise and “heal” once the acids have been.

The role of saliva in the development of caries and periodontal diseases introduction saliva is a complex oral ﬂuid consisting of a mixture of secretions from the major salivary glands and the minor glands of the oral mucosa. The crucial role played by the actions of saliva in controlling the equilibrium between de- and remineralization in a cariogenic environment is demonstrated by the effects on caries incidence of salivary dysfunction and by the distribution of sites of caries predilection to those where salivary effects are restricted. The role of trace elements present in saliva on dental caries is still not clear thus this study was designed to evaluate the effect of certain salivary trace elements like copper, potassium, fluoride, selenium and lead on the caries experience of children. Saliva, or spit, plays a significant role in maintaining oral health it is derived from blood and acts as the bloodstream of the mouth what this means is, like blood, saliva helps build and maintain the health of soft and hard tissues.
The present study was undertaken to evaluate the ph, buffering capacity, viscosity and flow rate of saliva in caries free, minimal caries and nursing caries children and to evaluate the relationship of these on the caries activity of children. Chapter 32 microbiology of dental caries dental caries is a chronic endogenous infection caused by the normal oral commensal flora the carious lesion is the result of demineralization of enamel – and later of dentine – by acids produced by plaque microorganisms as they metabolize dietary carbohydrates. The components of saliva, its functions in maintaining oral health and the main factors that cause alterations in sali- vary secretion will be reviewed, the importance of saliva in caries development and bacterial plaque formation will be.
