Systemic Markers of Inflammation: 9- and 12-Month Follow-Up Post Non-Surgical Periodontal Therapy

Systemic Markers of Inflammation: 9- and 12-Month Follow-Up Post Non-Surgical Periodontal Therapy With and Without Minocycline HCl Microspheres, 1mg

The primary goal of this study is to determine the amount of three systemic markers of inflammation: 1) Hemoglobin A1c (Hgb A1c, 2) High Sensitivity C-Reactive Protein (hsCRP), and 3) Haptoglobin (Hp) at 9 and 12 month follow-up post scaling and rootplaning (SRP) with and without minocycline HCl microspheres, 1 mg.

Participants from a randomized controlled clinical trial approved by the University of Minnesota (UMN) Institutional Review Board (IRB) STUDY00004876 and registered on ClinicalTrials.gov (NCT03762915) identifying the effects of SRP with and without minocycline HCl microspheres, 1 mg on periodontal pathogens and systemic inflammatory markers in the blood serum will be invited to participate in this 9 and 12 month follow-up study.
