Signal-Transducing Adaptor Proteins in Periodontal Disease

Completed

Conditions studied: Periodontitis, Gingivitis

In brief

This study will look at certain proteins in the gums, saliva, and gum fluid of people with healthy gums, gingivitis (mild gum inflammation), or periodontitis (more severe gum disease). The proteins to be studied called STAP-1, STAP-2, STAT3, STAT5A, NLRP3, and CASP3, are known to be involved in inflammation and cell health in other diseases, but their role in gum disease is not well understood. Seventy-five healthy adults will be grouped by their gum health status. Samples of saliva and gum fluid will be collected and tested, and gum tissue samples will be collected from a subset of participants during routine dental treatment. Researchers will measure the levels of these proteins and look for patterns linking them to the severity of gum disease. The results are expected to show whether these proteins are found at different levels in people with periodontitis compared to those with healthy gums, suggesting they may play a role in how gum disease develops and progresses. This information may help researchers better understand the biological processes behind periodontal disease and could eventually contribute to new ways of detecting or treating it.

You may qualify if…

• Inclusion criteria for the Healthy Control group were: presence of ≥ 20 teeth in the mouth, probing pocket depth (PPD) ≤ 3 mm, the percentage of bleeding sites for the whole mouth < 10%, and, on radiographic examination, a distance of ≤ 3 mm between the cemento-enamel junction and the alveolar bone crest in 95% of all teeth. Inclusion criteria for the Gingivitis group were: presence of ≥ 20 teeth in the mouth, PPD ≤ 3 mm, % of bleeding sites for the whole mouth ≥ 10%, and, on radiographic examination, a distance of ≤ 3 mm between the cemento-enamel junction and the alveolar bone crest in 95% of all teeth. Inclusion criteria for the Stage 3 Periodontitis group were: presence of ≥ 15 teeth in the mouth, more than 30% of teeth affected by periodontal disease, affected teeth exhibiting probing depths of 6 mm or more and clinical attachment loss (CAL) of ≥ 5 mm, vertical bone loss of 3 mm or more, class 2 or 3 furcation involvement, and radiographic evidence of alveolar bone loss extending to the middle third and beyond (33%) in the relevant teeth

You may not qualify if…

• Exclusion criteria for all groups were defined as: presence of any systemic disease, regular use of any medication, smoking, pregnancy or lactation, periodontal treatment within the last 6 months, antibiotic use within the last 6 months, and the presence of prosthetic restorations on the teeth to be sampled.
