Antimicrobial effectiveness of chitosan as a suture coating in oral and maxillofacial surgery: a systematic review. Odontoestomatología [online]. 2022, vol.24, n.40, e317.  Epub 01-Dez-2022.

Postoperative infections are increasingly common, as well as the increase in bacterial resistance mechanisms to a diverse class of broad-spectrum antibiotics. Hence the need to find a biocompatible and antimicrobial natural material to use as suture coating since this is considered an intrinsic factor in the process of these complications. This review aims to carry out a systematic search on the antimicrobial effectiveness of chitosan used as suture coating in oral and maxillofacial surgery. The search was carried out in two databases: PubMed and ScienceDirect from February to March 2021. PRISMA guidelines for systematic reviews were followed. The five articles from in vitro or in vivo studies showed that chitosan coating on sutures inhibits Gram-positive and Gram-negative microorganisms, exhibiting greater activity against Gram-negative microorganisms. It is concluded that chitosan coating on sutures could supplement and improve the properties of currently commercial antimicrobial sutures, reduce postoperative infections, and accelerate the healing processes.
