Study on Biomarkers of Periodontitis and Type 2 Diabetes Mellitus in Males and Females 30 - 70 Years of Age

The purpose of this study is to learn about the interactions of markers of type 2 diabetes (T2DM) and periodontitis (PD). Study VPE00001 is a multi-center cross-sectional study. Participants will be categorized based on point-of-care hemoglobin A1c (HbA1c) and periodontal disease (PD) staging into 9 subgroups. The key objectives of the study are: * To evaluate immune signatures in well-characterized populations with or without PD and/or T2DM * To evaluate baseline clinical biomarkers of T2DM and PD in well-characterized populations * To evaluate the influence of clinical, immunological, and microbiological biomarkers on the bidirectional relationship between T2DM and PD
