    The aim of the study was to determine the frequency of temporomandibular joint (TMJ) disorders in patients with rheumatoid arthritis evaluated at San José Hospital, Callao. The methodology used was observational, descriptive, retrospective, and cross-sectional. A total of 125 patients diagnosed with rheumatoid arthritis were analyzed using non-probabilistic convenience sampling. The "Helkimo Index modified by Maglione" and the "Fonseca Anamnestic Index," recorded in medical histories, were employed. Statistical analysis was performed using SPSS 25, applying the chi-square test along with absolute and relative frequencies, averages, and standard deviations. Results: TMJ disorders were observed in 76.8% of patients, with a similar frequency between males and females (p=0.110), but more frequent in older age groups (p=0.039). The main signs and symptoms included a maximum mandibular opening of 30 to 39 mm, right and left lateral movements of 4 to 6 mm, and maximum protrusion of 4 to 6 mm. Additionally, 56% presented mandibular deviation and/or joint noises during opening movement, 53.6% reported pain during a single movement, 54.4% experienced pain in at least three masticatory muscles during activity, and 53.6% reported pain upon palpation in the pre-auricular region. TMJ disorders were mild, moderate, and severe in 28.0%, 19.2%, and 24.8% of patients, respectively, with similar severities between genders (p=0.049) but more severe in older age groups (p=0.005). Conclusion: Approximately 7 out of 10 patients with rheumatoid arthritis included in the study presented TMJ disorders, with similar frequency, signs, symptoms, and severity between males and females, but higher percentages in older age groups.
