Alpha and beta diversity analyses, differential abundance testing, and microbial functional prediction were conducted. Statistical analyses were corrected for multiple comparisons using false discovery rate (FDR) adjustment where applicable. Associations with food and lifestyle habits were also examined.</div></div><div><h3>Results</h3><div>Substance users exhibited significantly lower alpha diversity, and beta diversity analyses revealed distinct clustering between the two groups. Firmicutes_D, Actinobacteria, <em>Rothia</em>, and <em>Streptococcus</em> were more abundant in substance users, whereas Bacteroidota, Proteobacteria, <em>Neisseria</em>, and <em>Prevotella</em> were enriched in healthy controls. Functional predictions indicated upregulation of biofilm formation and xenobiotic degradation pathways in substance users. Exposure to Jhum cultivation, prenatal smoking, and consumption of fermented pork fat (saum) were correlated with microbial composition.</div></div><div><h3>Conclusions</h3><div>Substance use and associated environmental exposures were linked to oral microbiome dysbiosis. Certain bacterial taxa may serve as potential microbial biomarkers of substance use in this high-risk tribal population, warranting further investigation.</div></div>","PeriodicalId":8288,"journal":{"name":"Archives of oral biology","volume":"180 ","pages":"Article 106418"},"PeriodicalIF":2.1,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145304953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
