The feasibility of phage therapy for periodontitis.

Abstract

Periodontitis, a chronic progressive inflammation caused by plaque biofilm, is the main cause of tooth loss in adults. For certain refractory periodontitis cases, it is difficult to achieve a good curative effect using the existing periodontal treatment approaches, which may be due to periodontal pathogenic mechanism in the affected periodontal tissue that the host cannot resist and eliminate. Various pieces of evidence collectively revealed that most studies are focusing on phages in periodontal disease. Several studies have reported periodontitis treatment using phage therapy, highlighting its features including specificity, rapid propagation, and effectiveness on bacteriophage biofilms. In this study, we focus on these reports, aiming to lay the foundation for improved periodontal treatment approaches.
