These issues are particularly pronounced in rural and remote populations, where access to specialized care and early diagnostic services is limited. Socioeconomic disparities, healthcare provider shortages, and geographic isolation contribute to delayed diagnoses and poorer outcomes in these settings. This systematic review evaluated 40 studies focused on early detection strategies for OPMDs and oral squamous cell carcinoma (OSCC) in underserved populations, particularly in rural and low-resource environments. Across 136,257 participants, the review identified diverse screening tools including oral visual examinations, toluidine blue staining, autofluorescence, chemiluminescence, mobile health (mHealth) applications, and artificial intelligence (AI)-based image analysis. The use of low-cost, portable, and technology-driven tools, especially those enabling remote diagnosis and task-sharing with frontline health workers, showed promise in increasing diagnostic accuracy and screening reach. However, variability in performance, training needs, and follow-up adherence remain key limitations. The review also highlighted widespread use of community-based strategies and the value of interdisciplinary collaboration, particularly where dental specialists are not readily available. Innovative, context-sensitive screening tools supported by interdisciplinary networks hold strong potential to enhance early detection of OPMDs and OSCC in rural and underserved communities. Mobile technologies and AI applications are emerging as practical adjuncts to traditional screening methods. To optimize impact, future efforts should prioritize validation of these tools against histopathological standards and the integration of trained non-specialist health workers in community-based screening programs.</div></div>","PeriodicalId":55993,"journal":{"name":"Journal of Stomatology Oral and Maxillofacial Surgery","volume":"127 3","pages":"Article 102667"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145598548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
