ObjectiveTo compare the mandibular movements in elderly people with and without temporomandibular disorder (TMD) associated with rheumatoid arthritis (RA).Study DesignThirty partially or completely edentulous elderly (65.33 ± 4.7 years) were assigned to two groups: with RA and TMD and without RA and TMD. Jaw chewing movements during Optocal mastication and the range of mandibular movements were evaluated using the JT-3D kinesiographic device, before and after new removable prosthesis insertion. Multiple comparisons were made with analysis of variance (ANOVA) and Tukey-Kramer's test.ResultsComparisons between groups before and after new prosthesis insertion revealed that the RA and TMD group had reduced opening angles (P < .05) during chewing. After insertion of new prostheses, both groups showed increased opening and closing angles during chewing (P < .05). The mandibular range of motion results showed that subjects with RA and TMD exhibited lower aperture and laterality movements (P < .05) than controls before and after new prosthesis insertion. However, there was an increase in aperture, lefty laterality, and protrusion values after new prosthesis insertion for both groups.ConclusionsTMD associated with RA may impair mandibular movements. Well-fitted prostheses may improve mandibular movements in elderly, especially those with RA. (ReBEC #RBR-6qkjzv).
