[Dysplasia-dependent abnormalities of the temporomandibular joint].

: The purpose of this study was to reveal the relationship between temporomandibular joint (TMJ) dysfunction and dysplasia of connective tissue (DCT). This investigation included 53 (34 female and 19 male) patients with TMJ internal derangement (ID) and 53 controls; 24 patients with marked and 53 patients with mild dysfunction of this joint. The symptoms of DCT (such as scoliosis, general joint hypermorbility) and TMJ ID were revealed. Results of this study prove that DCT is one of etiological factors of TMJ ID. The relationship between type of ID and severity of DCT was revealed.
