Oromandibular dystonia following dental treatment: case reports and discussion.
Oromandibular dystonia (OMD) is a movement disorder characterised by involuntary, repetitive, and patterned muscle contractions of varying severity, affecting the jaws, tongue, face, and pharynx. It is most commonly idiopathic or medication-induced, but peripheral trauma sometimes precedes the condition. There have been several reports of OMD following dental treatment, and this paper discusses two cases which occurred following extractions and full dentures.
