dc.description.abstractThe aim was to analyze the characteristics of the temporomandibular joint (TMJ) in a group of adult patients suffering from Steinert's muscular dystrophy (DM1). This study included 42 adult patients aged between 21 and 69 years (mean = 38.7619; SD = 12.74) who were diagnosed for DM1. Study was conducted using the MRI of right and left TMJ sagittal images taken in maximum intercuspidation position and maximum oral opening without pain, and the following were discussed: a) the quality of the cortical bone in the mandibular fossa, tuberosity, and mandibular head; b) the relationship of mandibular head-disc-joint tuberosity in maximum intercuspidation position; c) the anatomical shape of the articular disc. All patients showed abnormalities in the shape and surface of the cortical bone in the mandibularfossa, tuberosity, and the mandibular head. With regard to the relationship of the mandibular head in the mandibular fossa, 41% was found in the region 2B, 29% in 1B, 18% in 1A, 9% in 2C, and 3% in 2A of the TMJ. About 49% of the disc in maximum intercuspidation position was found on the mandibular head, 26% were anterior displaced, 14% had anterior dislocations, 38% had alterations in the form of disc, and 30% had preserved the anatomical shape. However, 98% of the discs showed hyposignal in T1 and T2. Using MRI, the decrease in the muscle activity in patients with DM1 was found to generate degenerative changes visible in the TMJ.en
