Emerging horizons of salivary diagnostics for periodontal disease

Abstract

The field of salivary diagnostics to allow risk determination for periodontal diseases is advancing. New technologies in proteomics, genomics and nanotechnologies have continued the discovery of discriminatory periodontal disease biomarkers. This review briefly overviews biomarker studies that have been completed in saliva for the detection of periodontal disease since 2010. Disease specific biomarkers could be used in risk determination, treatment planning and disease progression. Currently, diagnostic tests are commercially available, and the development of point-of-care tests is expanding. Even though challenges remain, salivary diagnostics for periodontal disease is promising and could facilitate the diagnostics and treatment in a clinical practice by dental practitioners.
