This combination may increase the risk of delayed diagnosis and malignant transformation. Objective: This PRISMA-compliant systematic review aimed to evaluate the prevalence of OPMDs and associated risk factors in prison populations, with a particular focus on identifying gaps in the current evidence. Methods. A systematic literature search was conducted in PubMed, Scopus and Cochrane Library using predefined search strategies. The final search yielded 24 records, which were screened according to PRISMA 2020 guidelines. After title and abstract screening, 10 full-text articles were assessed for eligibility, and 5 cross-sectional studies were included in the qualitative synthesis following independent review. Results: The included studies revealed a substantial burden of oral mucosal lesions in incarcerated populations. Premalignant lesions were reported in a significant proportion of inmates, with oral submucous fibrosis particularly prevalent in some cohorts. Additionally, a high prevalence of oral high-risk HPV infection and widespread oral manifestations were observed. Tobacco use, often combined with betel quid, alcohol, or illicit drugs, emerged as the primary and consistently associated risk factor for oral lesions. Conclusions: Prison populations appear to represent a high-risk group for OPMDs due to the combined effect of behavioral and structural risk factors. However, the limited number of available studies, their cross-sectional design, and methodological heterogeneity prevent definitive conclusions. Further longitudinal and methodologically robust studies are needed to better define prevalence patterns and support targeted screening and prevention strategies in correctional settings.<\/jats:p>","DOI":"10.3390\/dj14050302","type":"journal-article","created":{"date-parts":[[2026,5,14]],"date-time":"2026-05-14T16:27:56Z","timestamp":1778776076000},"page":"302","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Prevalence and Risk Factors of Potentially Malignant Oral Lesion in Prison Population: A Systematic Review"],"prefix":"10.3390","volume":"14","author":[{"given":"Erika","family":"Roncarati","sequence":"first","affiliation":[{"name":"Department of Translational Medicine, University of Ferrara, 44121 Ferrara, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saverio","family":"Ceraulo","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, University of Milano-Bicocca, 20100 Monza, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-1419-0898","authenticated-orcid":false,"given":"Antonio","family":"Barbarisi","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, University of Milano-Bicocca, 20100 Monza, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6659-2094","authenticated-orcid":false,"given":"Gianluigi","family":"Caccianiga","sequence":"additional","affiliation":[{"name":"Department of Translational Medicine, University of Ferrara, 44121 Ferrara, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9639-6676","authenticated-orcid":false,"given":"Francesco","family":"Carinci","sequence":"additional","affiliation":[{"name":"Department of Translational Medicine, University of Ferrara, 44121 Ferrara, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3550-1812","authenticated-orcid":false,"given":"Dorina","family":"Lauritano","sequence":"additional","affiliation":[{"name":"Department of Translational Medicine, University of Ferrara, 44121 Ferrara, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Korkosz, R., Trzcionka, A., and Hildebrandt, T.
