Trial Summary

What is the purpose of this trial?

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.

Experimental Treatment

Group I: Periodontitis Stage IVExperimental Treatment1 Intervention

Individuals included in this cohort, other than meet the eligibility criteria, should present clinical sign of periodontal defined as Stage IV according to the American Academy of Periodontology. We anticipate low to moderate number of participants in this cohort. No interventions are anticipated.

Group II: Periodontitis Stage IIIExperimental Treatment1 Intervention

Individuals included in this cohort, other than meet the eligibility criteria, should present clinical sign of periodontal defined as Stage III according to the American Academy of Periodontology. We anticipate moderate to high number of participants in this cohort. No interventions are anticipated.

Group III: Periodontitis Stage IIExperimental Treatment1 Intervention

Individuals included in this cohort, other than meet the eligibility criteria, should present clinical sign of periodontal defined as Stage II according to the American Academy of Periodontology. We anticipate a moderate number of participants in this cohort. No interventions are anticipated.

Group IV: Periodontitis Stage IExperimental Treatment1 Intervention

Individuals included in this cohort, other than meet the eligibility criteria, should present clinical sign of periodontal defined as Stage I according to the American Academy of Periodontology. We anticipate low to moderate number of participants in this cohort. No interventions are anticipated.

Group V: Perio-HealthyExperimental Treatment1 Intervention

Individuals included in this cohort, other than meet the eligibility criteria, should present no clinical sign of periodontal disease. We anticipate to find from a very small number to none participants at this cohort. No intervention are anticipated.
