Abstract
Evaluate the relation of rheumatoid arthritis (RA) and bone changes in the temporomandibular joint diagnosed by cone-beam computed tomography (CBCT). This systematic review and meta-analysis were recorded in the PROSPERO database, using the CRD42020153246 protocol. The electronic searches were performed in the following databases: Pubmed, Scopus, Web of Science, Lilacs, Cochrane, and Open Grey. Cross-sectional studies that evaluated patients with RA with bone changes in the temporomandibular joint diagnosed by CBCT, without language restriction or publication date, were included. Meta-analysis was performed in Stata Software (StataCorp, TX, USA, version 12.0), using the metan, and a random effects model, and the risk of different bone alterations occurring in adults with and without arthritis was estimated using odds ratios (ORs) as a pooled measure of effect. Forest plots were used to present the isolated and the pooled effects (ORs and 95% CI). Six studies were used for qualitative synthesis and 2 studies for quantitative synthesis. All studies diagnosed higher prevalence changes in the bone structures of the TMJ of RA patients, described as erosion, flattening, sclerosis, and osteophytes. Meta-analysis showed that the chance of bone changes occurring in components of the TMJ is greater in individuals who have RA. There is an association between RA and bone changes in TMJ structures diagnosed through CBCT, as RA patients were more likely to have osteoarthritic changes in this joint. Understanding the existence of an association between bone alterations in TMJ and RA can assist in the management of patients.
