The aim of this study was to identify the prevalence of orofacial pathognomonic conditions in patients with systemic scleroderma using only randomised prospective studies that investigated the treatment of oral and maxillofacial changes, highlighted associations between the disease and Sjogren\u2019s syndrome, and\/or analysed the effect of oral hygiene. Methods: The literature was systematically reviewed based on Cochrane Library, EMBASE, PubMed, Scopus, and Web of Science articles published up to March 2020. The primary endpoint of this analysis was defined as an estimation of the prevalence of oral mucosal changes in different areas of the oral cavity (oral mucosa, tongue, lip, periodontal status, bones, and other regions) in patients suffering from scleroderma. Therefore, a systematic literature search (Cochrane Library, EMBASE, PubMed, Scopus, and Web of Science) was conducted and limited by the publication date (1950-03\/2020) and the publication language (English). Extracted frequencies were pooled using methods for meta-analysis. In order to obtain the highest level of evidence, only prospective study reports were considered to be eligible. Results: After full-text screening, 14 (766 patients) out of 193 publications were eligible for the final analysis. Twelve studies produced reliable results in the final data sets. Calculation of the pooled effect estimate (random effects model) revealed a prevalence of 57.6% (95% CI: 40.8\u201372.9%) for the main area \u201clip\u201d. For the area \u201coral mucosa\u201d, a prevalence of 35.5% (95% CI: 15.7\u201362.0%) was calculated. The prevalence for \u201cother regions\u201d was only based on studies with salivary changes and was calculated to be 25.4% (95% CI: 14.2\u201341.3%). Conclusion: The most pathognomonic conditions in the orofacial region in patients with systemic scleroderma affect the lips, oral mucosa, and salivary glands.<\/jats:p>","DOI":"10.3390\/ijerph18105238","type":"journal-article","created":{"date-parts":[[2021,5,14]],"date-time":"2021-05-14T10:54:22Z","timestamp":1620989662000},"page":"5238","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Prevalence of Oral and Maxillofacial Disorders in Patients with Systemic Scleroderma\u2014A Systematic Review"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8476-183X","authenticated-orcid":false,"given":"Korbinian","family":"Benz","sequence":"first","affiliation":[{"name":"Department of Oral Surgery and Policlinical Ambulance, Faculty of Health, Witten\/Herdecke University, Alfred-Herrhausen-Str. 45, 58448 Witten, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christine","family":"Baulig","sequence":"additional","affiliation":[{"name":"Faculty of Health, Institute for Medical Biometry and Epidemiology, Witten\/Herdecke University, Alfred-Herrhausen-Str. 50, 58448 Witten, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1645-4475","authenticated-orcid":false,"given":"Stephanie","family":"Knippschild","sequence":"additional","affiliation":[{"name":"Faculty of Health, Institute for Medical Biometry and Epidemiology, Witten\/Herdecke University, Alfred-Herrhausen-Str. 50, 58448 Witten, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank Peter","family":"Strietzel","sequence":"additional","affiliation":[{"name":"Charit\u00e9 Centre for Dentistry, Department Periodontology, Oral Medicine and Oral Surgery, Charit\u00e9-University Berlin, Assmannshauser Str. 4-6, 14197 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicolas","family":"Hunzelmann","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Venerology, University of Cologne, Kerpener Str. 62, 50937 K\u00f6ln, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jochen","family":"Jackowski","sequence":"additional","affiliation":[{"name":"Department of Oral Surgery and Policlinical Ambulance, Faculty of Health, Witten\/Herdecke University, Alfred-Herrhausen-Str. 45, 58448 Witten, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1038\/nrdp.2015.2","article-title":"Systemic sclerosis","volume":"1","author":"Allanore","year":"2015","journal-title":"Nat.
