Antimicrobial Sensitivity Associated with Porphyromonas gingivalis Present in Periodontitis Frameworks: An Integrative Review

Objectives: The Gram-negative anaerobic bacterium Porphyromonas gingivalis is identified as one of the most important causes of the chronic form of periodontitis. This work aimed to analyze the sensitivity of P. gingivalis to antibiotics and antimicrobial agents.

Study Design: Integrative literature review.

Methodology: Through a careful analysis of clinical trials published in the last 5 years. A bibliographic search was carried out in the PubMed, Scielo and Google Scholar databases. Three keywords were established and verified on the DeCs-Descritores em Ciências da Saúde website for the literary search “Antimicrobial resistance”, “Periodontal biotherapy” and “Porphyromonas gingivalis”. 66 articles were found. Of these, animal studies, studies that did not involve patients diagnosed with periodontitis according to the 2017 World Workshop on the Classification of Periodontal and Peri-implant Diseases and Conditions, and studies on peri-implantitis were excluded. Studies that used only surgical therapy without association with at least one antibiotic or antimicrobial and duplicate studies were excluded.

Results: This integrative review presents the results of 19 studies. Amoxicillin, Metronidazole and Azithromycin are the most commonly used antibiotics. Photodynamic therapy has demonstrated benefits in reducing inflammation and P. gingivalis
