Resume Objectifs L’objectif de la presente etude a ete d’evaluer la prevalence des atteintes de l’articulation temporomandibulaire (ATM) de la presentation clinique et des donnees de l’imagerie par resonance magnetique (IRM) dans une cohorte de patients du sud de l’Italie atteints de sclerodermie systemique (ScS). Methodes Vingt-sept patients atteints de ScS (12 ScS diffuse, 15 ScS limitee, âge moyen 53,9, ET ± 1,2) et 28 sujets sains (âge moyen 54,8, ET ± 4,2) ont ete inclus dans cette etude de cohorte observationnelle. Chez tous les patients on a realise un examen clinique visant a evaluer la presence de bruits de l’ATM, la douleur dans la region de l’ATM, la sensibilite des muscles masticateurs et la limitation de l’ouverture de la bouche ainsi qu’une evaluation de la douleur, un examen IRM et une evaluation des indices d’anamnese et de dysfonction. Resultats Dans le groupe de patients, les observations cliniques et par IRM ont revele un plus grand nombre de symptomes de l’ATM et de dysfonctions que dans le groupe temoin. Les distributions de frequence des symptomes ont ete significativement differentes (p Conclusion Cette etude montre que l’atteinte de l’ATM est courante chez les patients souffrant de ScS et est correlee avec la duree et la gravite de la maladie. Elle plaide pour la promotion d’un examen de l’ATM dans les services de rhumatologie, ainsi que d’une prise en charge de la douleur et de la fonction appropriee pour les patients.

Objectives: The aim of the present study was to assess the prevalence of temporomandibular joint (TMJ)symptoms, clinical and magnetic resonance imaging (MRI) findings in a cohort of Southern Italian patientswith SSc.Methods: Twenty-seven patients with SSc (12 diffuse, 15 limited, mean age 53.9, SD ± 1.2) and 28 healthysubjects (mean age 54.8, SD ± 4.2) were enrolled in this observational cohort study. In all patients, clinicalexamination for assessing the presence of TMJ sounds, pain in the TMJ area, tenderness of masticatorymuscles, limited mouth opening, pain assessment, MRI scan and Anamnestic and Dysfunctional Indexwere performed.Results: The test groups reported more clinical and MRI findings of TMJ symptoms and dysfunction thancontrol group. The frequency distributions of symptoms were significantly different (P < 0.05), in thetest groups for TMJ sounds, pain during mandibular movement and difficulty in the maximum mouthopening. There was also a significant decrease (P < 0.001), in the test groups, in the mean of leftward,rightward laterotrusion and protrusion. Correlation analysis allowed to affirm that maximum openingleftward laterotrusion, protrusion and click were significantly correlated to Modified Rodnan Skin Score.The mean duration of disease was significantly correlated, ever in total SSc group, only for the maximummouth opening value.Conclusion: This study demonstrates that TMJ involvement is common in SSc patients and is correlatedwith a length and involvement of disease and supports the notion that TMJ examination should be encour-aged in the rheumatology setting and clinicians should provide a right pain management and patientsupport.
