Locally Delivered Minocycline in Advanced Periodontitis

Overview

Local drug delivery provides higher concentrations in the availability of the drug at the specific infected sites with the advantage of sustained release. Periocline is a long acting , sustained release local drug delivery system consisting of 2% minocycline hydrochloride in an ointment containing microcapsule type particles. Periocline contains 20mg of minocycline in 0.5 gm of gel in a disposable polypropylene applicator (2% minocycline HCl). Research has yielded promising results with the local application of minocycline in the treatment of periodontal disease, compared with other non-surgical therapies. However, there is scarcity of reports on the use of local delivery agents with respect to new range of putative pathogens in advanced periodontitis, wherein the tissue invasive anaerobic organisms are present and possibly compromised host response, hence resulting in an exaggerated breakdown of periodontal tissues at the affected sites. The effect of Minocycline on new putative pathogens, such as Filifactor alocis and oral phylotypes of phyla Synergistetes and TM7 (referred to hereafter as oral Synergistetes and oral TM7s), has not been investigated yet. Hence, the aim of the present study is to evaluate the efficacy of a local delivery agent containing minocycline (Periocline, Sunstar, Japan) as an adjunct to SRP in the treatment of deep periodontal pockets around teeth in advanced periodontitis and the antimicrobial effect on the red complex and the new putative pathogens.

The subjects for this randomized controlled, parallel arm study will be selected from the primary health care in the Faculty of Dentistry, MAHSA University. In this clinical trial, 50 patients with advanced periodontitis will be enrolled in the study.
