The clinical features of the fibrous-ankylosis are severely limited mouth-opening capacity (limited range of motion during the opening), usually no pain and no joint sounds, marked deflection to the affected side and marked limitation of movement to the contralateral side. A variety of factors may cause TMJ ankylosis, such as trauma, local and systemic inflammatory conditions, neoplasms and TMJ infection. Rheumatoid arthritis (RA) is one of the systemic inflammatory conditions that affect the TMJ and can cause ankylosis. The aim of this study is to present a case of a female patient diagnosed with bilateral asymptomatic fibrous-ankylosis of the TMJ associated with asymptomatic rheumatoid arthritis. This case illustrates the importance of a comprehensive clinical examination and correct diagnosis of an unusual condition causing severe mouth opening limitation.<\/jats:p>","DOI":"10.1590\/s0103-64402012000600025","type":"journal-article","created":{"date-parts":[[2013,1,19]],"date-time":"2013-01-19T10:10:27Z","timestamp":1358590227000},"page":"779-782","source":"Crossref","is-referenced-by-count":12,"title":["Bilateral asymptomatic fibrous-ankylosis of the temporomandibular joint associated with rheumatoid arthritis: a case report"],"prefix":"10.1590","volume":"23","author":[{"given":"Carolina Ortigosa","family":"Cunha","sequence":"first","affiliation":[{"name":"University of S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L\u00edvia Maria Sales","family":"Pinto","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luana Menezes de","family":"Mendon\u00e7a","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aline Dantas Di\u00f3genes","family":"Saldanha","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Cl\u00e1udia de Castro Ferreira","family":"Conti","sequence":"additional","affiliation":[{"name":"University of North Paran\u00e1,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulo C\u00e9sar Rodrigues","family":"Conti","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"122","DOI":"10.1016\/j.jcms.2009.04.006","article-title":"Ankylosis of the temporomandibular joint","volume":"38","author":"Gundlach KK","year":"2010","journal-title":"J Craniomaxillofac Surg","ISSN":"https:\/\/id.crossref.org\/issn\/1010-5182","issn-type":"print"},{"key":"ref2","series-title":"Peterson's principles of oral and maxillofacial surgery: Second ed","volume-title":"Hypomobility and hypermobility disorders of the temporomandibular joint","author":"Meredith A","year":"2004"},{"key":"ref3","series-title":"Orofacial pain: guidelines for assessment, diagnosis and management","author":"de Leeuw R","year":"2008","edition":"4"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"166","DOI":"10.1016\/S1079-2104(99)70267-2","article-title":"Functional restoration by gap arthroplasty in temporomandibular joint ankylosis: a report of 50 cases","volume":"87","author":"Roychoudhury A","year":"1999","journal-title":"Oral Surg Oral Med Oral Pathol Oral Radiol Endod","ISSN":"https:\/\/id.crossref.org\/issn\/1079-2104","issn-type":"print"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1016\/j.joms.2007.08.013","article-title":"Etiology of temporomandibular joint ankylosis secondary to condylar fractures: the role of concomitant mandibular fractures","volume":"66","author":"He D","year":"2008","journal-title":"J Oral Maxillofac Surg","ISSN":"https:\/\/id.crossref.org\/issn\/0278-2391","issn-type":"print"},{"key":"ref6","first-page":"449","article-title":"Temporomandibular joint ankylosis","volume":"187","author":"Chandra P","year":"1985","journal-title":"Prog Clin Biol Res","ISSN":"https:\/\/id.crossref.org\/issn\/0361-7742","issn-type":"print"},{"key":"ref7","doi-asserted-by":"crossref","first-page":"527","DOI":"10.1016\/S1726-4901(08)70055-8","article-title":"Temporomandibular joint disorders in patients with rheumatoid arthritis","volume":"70","author":"Lin YC","year":"2007","journal-title":"J Chin Med Assoc"},{"key":"ref8","doi-asserted-by":"crossref","first-page":"97","DOI":"10.2334\/josnusd.43.97","article-title":"Ankylosis of the temporomandibular joint caused by rheumatoid arthritis: a pathological study and review","volume":"43","author":"Kobayashi R","year":"2001","journal-title":"J Oral Sci","ISSN":"https:\/\/id.crossref.org\/issn\/1343-4934","issn-type":"print"},{"key":"ref9","doi-asserted-by":"crossref","first-page":"897","DOI":"10.1016\/j.joms.2005.03.004","article-title":"Preservation of disc for treatment of traumatic temporomandibular joint ankylosis","volume":"63","author":"Long X","year":"2005","journal-title":"J Oral Maxillofac Surg","ISSN":"https:\/\/id.crossref.org\/issn\/0278-2391","issn-type":"print"},{"key":"ref10","doi-asserted-by":"crossref","first-page":"19","DOI":"10.1038\/sj.dmfr.4600660","article-title":"Imaging of temporomandibular joint ankylosis","volume":"31","author":"El-Hakim IE","year":"2002","journal-title":"A new radiographic classification.
