Porphyromonas gingivalis, a key pathogen in periodontitis, has historically been susceptible to metronidazole. However, emerging reports of phenotypic resistance and the potential presence of resistance genes, such as the <i>nim</i> gene, raise concerns regarding its continued efficacy. The objective of the study was to evaluate the prevalence of metronidazole resistance in <i>P</i>. <i>gingivalis</i>, focusing on both phenotypic resistance and molecular detection of resistance genes. This systematic review was registered in PROSPERO (ID: 1070147) and conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. A comprehensive literature search was performed in PubMed, Scopus, and Web of Science for the studies published between January 2005 and April 2025. Studies reporting phenotypic or genotypic metronidazole resistance in <i>P. gingivalis</i> among human subjects with periodontitis were included. Study quality was assessed using the Newcastle-Ottawa Scale and Risk of Bias in Nonrandomized Studies of Interventions-I tool. Due to methodological heterogeneity, results were synthesized qualitatively rather than through meta-analysis. Eight studies were included. Three studies reported phenotypic resistance to metronidazole exceeding 25%, whereas the others identified genotypic resistance with a prevalence of around 30%. Molecular analyses indicated that <i>nim</i> genes were rarely detected or absent. The presence of phenotypic resistance without consistent genotypic evidence suggests alternative mechanisms, such as biofilm-associated tolerance or efflux activity. Variations in geographic location, antimicrobial susceptibility testing methods, and prior antibiotic exposure contributed to heterogeneity across studies. This review suggests that phenotypic metronidazole resistance in <i>P. gingivalis</i> occurs in certain populations, with low resistance in surveillance settings, where <i>nim</i> genes are rarely detected. However, this evidence is limited by heterogeneity in study design and resistance assessment and findings should be interpreted cautiously.</p>","PeriodicalId":15890,"journal":{"name":"Journal of Indian Society of Periodontology","volume":"30 1","pages":"45-52"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13286531/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148308341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
