Contribution of orodental status to the intensity of orofacial tardive dyskinesia: an interdisciplinary and video-based assessment.

Background: Tardive dyskinesia (TD) is a neurological motor complication eventually arising in one-third of patients chronically exposed to antipsychotic drugs. Some orodental peripheral factors have been reported to influence TD.

Objective: To measure orodental factors such as temporomandibular joint function, static occlusal contacts, and denture condition, and attempt correlations with orofacial TD intensity.
