This study aims to quantify the prevalence of individual oral outcomes in IBD patients and to evaluate their association with the disease compared with healthy controls. Methods: A systematic review was conducted in accordance with PRISMA guidelines. Eligible studies were identified through searches of PubMed\/MEDLINE, Cochrane Library, Scopus, Ovid MEDLINE, and EMBASE. Studies reporting oral signs and symptoms in IBD patients were included. A single-arm meta-analysis was performed for oral ulcerations, dry mouth, halitosis, tongue alterations, oral aphthae, stomatitis, and taste changes. Risk of bias was assessed using the Newcastle\u2013Ottawa Scale. Results: Twenty-one studies including 7791 participants (5914 IBD patients and 1877 controls) were analyzed. The pooled prevalence of oral ulcerations was 20% (95%CI11\u201333), dry mouth 32% (95%CI14\u201359), halitosis 22% (95%CI7\u201351), and tongue alterations 11% (95%CI4\u201324). Comparative analyses showed no statistically significant differences between IBD patients and controls for these outcomes. Conclusions: Although oral manifestations are frequently reported in IBD patients, their prevalence does not significantly differ from that of the general population. Standardized, multicenter studies are required to clarify disease-specific associations.<\/jats:p>","DOI":"10.3390\/dj14050250","type":"journal-article","created":{"date-parts":[[2026,4,23]],"date-time":"2026-04-23T17:04:59Z","timestamp":1776963899000},"page":"250","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Oral Manifestations in Patients with Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-8717-7121","authenticated-orcid":false,"given":"Veronica","family":"Scocca","sequence":"first","affiliation":[{"name":"Maxillofacial Surgery Unit, Department of Neurosciences, Reproductive and Odontostomatological Sciences, University Federico II of Naples, Via Pansini 5, 80131 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giovanni","family":"Sarnelli","sequence":"additional","affiliation":[{"name":"Department of Clinical Medicine and Surgery, University of Naples Federico II, Via Pansini 5, 80131 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5996-4259","authenticated-orcid":false,"given":"Marcella","family":"Pesce","sequence":"additional","affiliation":[{"name":"Department of Clinical Medicine and Surgery, University of Naples Federico II, Via Pansini 5, 80131 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9869-9240","authenticated-orcid":false,"given":"Carlos","family":"Navarro-Cu\u00e9llar","sequence":"additional","affiliation":[{"name":"Maxillofacial Surgery Department, Hospital General Universitario Gregorio Mara\u00f1\u00f3n, 28007 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6479-6130","authenticated-orcid":false,"given":"Giovanni","family":"Dell\u2019Aversana Orabona","sequence":"additional","affiliation":[{"name":"Maxillofacial Surgery Unit, Department of Neurosciences, Reproductive and Odontostomatological Sciences, University Federico II of Naples, Via Pansini 5, 80131 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"322","DOI":"10.1016\/j.crohns.2013.01.010","article-title":"ECCO-Epicom.
