ABSTRACT
Periodontitis is a chronic inflammatory disease associated with obesity, type 2 diabetes, and cardiovascular disease, and has become a serious public health issue. Antibacterial treatment and mechanical debridement are the main treatment strategies for periodontitis. However, side effects and bacterial resistance might lead to treatment failure. Nanotechnology systems have new opportunities for the management of periodontitis. With benefits including superior targeting and fewer side effects, drug delivery systems constructed with nanoparticles (NPs) may provide local, delayed, and regulated drug release. When combined with immunomodulatory therapy, tissue regeneration, and antibacterial therapy, a high drug loading capacity of individual medications or therapeutic combinations is made possible by the large surface area to volume ratio of nanoparticles, providing synergistic beneficial effects. This paper reviews the progress in the research and application of nanoparticle-based drug delivery systems in the treatment of periodontitis. We focused on the pathophysiology of periodontitis, introduced the rational design of nano-drug delivery systems, and concentrated on the local approaches to treatment for periodontitis. Furthermore, the future challenges and research prospects for nanoparticle-based drug delivery systems in the treatment of periodontitis are also covered in this paper.
