Dental caries and periodontitis are important oral infections that if we can diagnose them as soon as possible, prevention may occur. In this study, we Searched data base such as PubMed, Elsevier, Scopus, and Google scholar to have comprehensive review on diagnostic role of saliva in dental caries and periodontitis. Nowadays, biomarkers in saliva are important clues in diagnosis. They are especially used in oral infections detection and prognosis. On the other hand, analysis of saliva can offer a cost-effective approach to screen for a larger population. So, improvement of using saliva and detecting biomarkers can be a helpful and useful step in diagnosis dental caries and periodontitis.
