Use of Salivary Markers to Heralding the Onset of Periodontal Disorders

Detailed Summary

The swelling of the gum, or periodontitis, is the leading cause for tooth loss, and currently affects up to 65 million adults only in the United States. One of the reasons for the widespread of periodontitis is because currently there are no definitive methods to detect the onset of gum disease. This lack of foresight impedes medical professionals to enact any preventive measures before the disease already manifests itself. We wish to expand our understanding towards the development of periodontitis by studying the expression and activity of salivary markers that have been associated with advanced stages of the disease, wherein the supporting tissues of tooth (periodontium) are already irreversibly destroyed. We hypothesize that a progressive shift in the expression of such salivary markers can indicate a change or evolution of periodontitis staging. In specific, we seek to establish a quantifiable relationship among levels of salivary proteases called MMPs, level of metal ions in different stages varying from health to periodontitis. The overall goal of this proposal is to enhance the predictability of periodontitis, as we are currently unable to diagnose the disease until the manifestation of its clinical signs and symptoms.
