ABSTRACT

Objective: To relate the clinical and imaging findings found in the temporomandibular joints with effusion in adolescents. Material and methods: 92 temporomandibular joints corresponding to 46 patients with joint effusion were studied. The following variables were evaluated: presence/absence of joint pain and noise, mouth opening, disc displacement and type of displacement, disc shape, retrodiscal protrusion, and bone marrow edema in the mandibular condyle. The severity of the effusion was classified according to Westesson and Brooks. The goodness of fit test using the chi square statistic (χ2) was used to determine if any category of the variables under study was predominant. Results: 40.8% of the patients presented pain and 58.9% joint noise. Mouth opening limitation was observed in 78.3% (p < 0.0001). Disc displacement was present in all evaluated joints (p < 0.0001); 53.2% of the discs showed reduction and 40.2% were displaced without reduction. 53.2% of the joints showed a bent articular disc (p < 0.02) 52.2% had a diagnosis of retrodiscal protrusion. No bone marrow edema was found in any joint. Conclusion: The presence of effusion was related to mouth opening limitation, disc displacement and morphological changes of the articular disc.
