Periodontitis Clinical Trials

Periodontitis is a bacterial inflammatory disease and antibiotic use is being empirically used as part of its treatment. However, a clinical practice guideline on periodontal treatment adjuncts published in 2015 identified weak evidence on the use of systemic antibiotics and large heterogeneity across small scale studies, suggesting that larger pragmatic clinical trials would benefit clinical decision making. This will be a prospective, randomized, placebo-controlled trial, stratified by practice and practitioner. The study will investigate the effectiveness of adjunctive antibiotics as adjunct to scaling and root planing (SRP) compared to SRP with placebo for the treatment of generalized stage II-III, grades A-C periodontitis in approximately 544 patient participants from about 34 National Dental PBRN practices. Periodontal data will be collected at baseline, re-evaluation (6 weeks), and final (12 months) study visits. Changes in periodontal clinical and patient-reported outcomes will be assessed to determine the effectiveness of SRP plus adjunctive systemic Amoxicillin / Metronidazole antibiotics (AMXM) versus SRP with Placebo.

This study is designed to evaluate the use of Emdogain® MI in a procedure where a significant portion of the lining of the sulcus is removed by curettage (similar to the traditional clinical procedure described as "gingival curettage") to the point of tissue mobility. This will be designated as a "non-incised minimally invasive flap access procedure". A videoscope will be utilized to assist with the requirement to adequately visualize and debride the root surface. This research project will define the approach used as a "non-incised minimally invasive flap access" approach and will be a modification of recognized minimally invasive techniques. This modification will be made by Dr. Harrel who first describe the minimally invasive periodontal approach and defined minimally invasive periodontal procedures in 1995. Read Less

To compare the diagnostic accuracy of extra-oral x-rays with intra-oral x-rays, in contrast to clinically observed measurements, for the detection of calculus and bone loss of either the suprabony or infrabony types in patients undergoing periodontal surgery. Read Less

The purpose of this study is to characterize the effect of minocycline microspheres (MM) administered as an adjunct to scaling and rooting planning (SRP) on the subgingival community composition and metatranscriptome functional profile, in comparison to a group treated with SRP only and to periodontally-healthy subjects.
