Coronavirus infections, Saliva, Dentistry, Containment of biohazards


Aim: Due to the importance of the salivary fluid in dentistry, this study aimed to carry out a literature review on the relationship between saliva and COVID-19, as well as its main implications in Dentistry.

Methods: An electronic search for publications was performed in the SciELO, PubMed, Scopus, EMBASE, and Cochrane Central Register of Controlled Trials databases using the following descriptors: “Saliva”, “oral cavity”, “oral mucosa”, “oral lesions “, and “Dentistry”, using the Boolean operator “AND” between all keywords cited individually with the term “COVID-19”. The studies were published from December 2019 to September 2020.

Results: The studies have shown that saliva represents an important means of transmission of SARS-CoV-2, which makes it necessary for dentists to comply with biosafety measures in order to reduce the possibility of SARS-CoV-2 infection. Likewise, the high viral load found in saliva allows it to be used as a path to COVID-19 diagnosis. Investigations have shown similar effectiveness in the saliva analysis compared to other conventional techniques. In this regard, more investigations need to be carried out to validate the methodology applied in current studies.

Conclusion: The detection of SARS-CoV-2 through saliva is very promising and has advantages in comparison to other biological fluids, as the collection of this fluid does not involve an invasive intervention, thus facilitating management by professionals and patients.
