Sampling of saliva is simple and effective. It is a simple method in that it does not require expertise for collection and is less expensive. Periodontal disease is a chronic microbial and inflammatory process characterized by the presence of pathogenic bacteria. Saliva, by its importance in biofilm formation and in host defense, secretes biomarkers that can play a significant role in the establishment and progression of periodontal disease. Determining salivary biomarkers helps in the early diagnosis of diseases and increases the success rate of the treatment.
