Several researchers associate the TMD with changes of TMJ articular surfaces. The careful identification of bone changes related to TMJ is critical, since these abnormalities are associated with signs and symptoms of TMD and the knowledge of TMD signs and symptoms is fundamental for correctly diagnosing and for adequate treatment planning. The aim of this study was to evaluate the morphological characteristics of the TMJ articular surfaces in patients with TMD diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). In addition, therelationship between increasing age-osteoarthrosis was evaluated. For the sample we selected 19 patients, 17 female and 2 male, referred to the "Unidad de Trastornos Cráneo Cérvico Mandibulares (UCRACEM) - Universidad de Talca, Chile". The imaging assessment was carried out by Cone-Beam Computed Tomography (CBCT). In the imaging analysis of the articular surfaces 11 joints (28.94%) showed normal morphology. The bone changes found were: sclerosis, flattening, erosion, osteoarthrosis, osteophytes, subcondral cysts. We found statistically significant difference between increasing age-osteoarthrosis (p=0.00). Considering our results we concluded that bone changes of the TMJ articular surfaces in patients with TMD are very common, with sclerosis as the most frequent finding.
