Clinical findings in the stomatognathic system in ankylosing spondylitis.

100 individuals with ankylosing spondylitis (AS-group) and a comparison group comprising 57 individuals (C-group) were examined for clinical symptoms from the stomatognathic system and occlusion. It was concluded that the AS-group differed significantly from the C-group with respect to mandibular mobility, tenderness to palpation of the temporomandibular joint and relation between the retruded and intercuspal position of the mandible. Clinical symptoms in the stomatognathic system were correlated to subjective general joint symptoms in the AS-group. Occlusal factors may also be of importance for the development of clinical symptoms in the stomatognathic system in this group.
