Local drug delivery in periodontitis treatment: A review of contemporary literature

Abstract

Traditional methods of non-surgical treatment of periodontitis, including mechanical scaling/root planing (SRP), do not guarantee remission of the disease. Local delivery of antimicrobial agents in periodontitis entails antimicrobial therapy placed directly in periodontal pockets. The advantage of this form of treatment is that the concentration of the drug after application significantly exceeds the minimum inhibitory concentration (MIC) and persists for up to several weeks. Therefore, many systems of locally applied devices, using a variety of antibiotics or antiseptics have been developed. There is continuous research aimed at introducing new forms of locally administered drugs, some of which have not proved to be effective, while others are promising. For almost 30 years such systems have been used for treatment as an adjuvant to SRP, and their efficacy has been evaluated. The aim of this article is to systematically review the contemporary literature regarding the currently available chemotherapeutics locally administered in the treatment of periodontitis.
