Salivary Sample Tests – What They Can Do

Saliva has a significant role in supporting the health of soft and hard tissues in the mouth. The defensive functions of saliva include maintaining a neutral oral pH, cleaning and remineralizing the dentition, aiding swallowing and digestion, and protecting oral tissue. Reduced salivary secretion can lead to multiple oral problems, such as dental caries, fungal infections, mucositis, and periodontal diseases. Saliva is also regarded as the mirror of the body, reflecting the overall patient's state of health.

Diagnostic Tool

The diagnostic properties of saliva are readily accessible, and the sample collection is non-invasive. A sample can be tested for proteins, electrolytes, hormones, antibodies, as well as other substances. The benefits are even greater when multiple samples over a period of time are obtained and tested.

Chair-side diagnostic tests and biosensor technologies are currently under development. These tests can be used to evaluate oral fluids for disease detection, which will also enable improved access and healthcare outcomes for patients. The detection of specific periodontal pathogens hidden in a patient’s mouth can promote treatment planning and risk assessment using hard data, rather than a subjective assessment.

For example, a saliva test can identify highly toxic bugs linked with aggressive forms of periodontal disease. The salivary test report will specifically state which antibiotics will be effective for each bacterial profile. Patients with periodontal disease can be periodically tested to determine if the process is active due to various bacteria. The salivary sample test results can be used to determine a treatment plan that is individualized for each patient, rather than providing a one-size-fits-all approach.

Future Development

Large-scale clinical trials and independent authentication studies are needed before noninvasive oral fluid tests become commercially available for the early detection of oral cancer and other systemic conditions. Further refinement of oral fluid screening tests to help identify individuals at increased risk for oral and systemic diseases holds great promise to strengthen our understanding of the relationship between overall health and oral health.

Dental practitioners can better explain and link the gap between oral and systemic health by implementing saliva testing. Additionally, the clinical events and the science of salivary diagnostic testing can have a positive impact on patient outcomes with minimal to no health risks or financial concerns for many patients.
