Methodological Considerations in Salivary Proteomics for Periodontal Research-A Review

Abstract

ABSTRACT The diagnosis and management of periodontal diseases can be enhanced by the identification of biomolecules which can predict disease susceptibility, indicate current disease activity, and monitor response to therapy. Salivary proteomics is a major avenue in the ongoing search for a biomarker in periodontal research. Saliva is a valuable diagnostic vehicle which “mirrors” oral and systemic health and disease. Standardized methods of saliva sampling and processing will increase diagnostic test accuracy and decrease bias in measurements. Prominent databases such as PubMed/Medline, PMC, Scopus, and Google Scholar were searched and literature evidence from January 2000 till September 2022 were studied to identify the methodological considerations employed in salivary proteomics for periodontal research. Evidence and recommendations in this regard were collated into this narrative review. The methods of saliva collection and processing presented in this review will help researchers conduct salivary proteomic studies with standardized protocols.
