Saliva as a Diagnostic Tool

Saliva is a biological  fluid which is clinically informative, for clinical  diagnosis  and for  monitoring  management  of patients with both  oral  & systemic  diseases. Saliva is considered as mirror  of  body  health.

It is  the product of the  secretions of  the  three  major  salivary  glands i.e  (parotid, submandibular, sublingual) and the numerous minor salivary glands mixed with other body  fluids such as bronchial and nasal secretions, blood constituents from wounds or bleeding gum, bacteria, viruses, fungi, exfoliated epithelial cells and food debris.
