Abstract
The clinical course and follow-up evaluation of drug induced open bite resulting in extra pyramidal syndrome from administration of antipsychotic drug (haloperidol) in a young patient with schizophrenia was followed for two and a half years. The results of the observation are as follows:
1. The open bite state continued as long as the drug was administered to the patient.
2. Improvement of the open bite state was confirmed with decrease in drug administration and disappeared with cessation of the drug.
Dentists involved in the treatment of occlusal disorders for young patients with psychotic disorders like schizophrenia should note that there is an increased frequency in occurrence of drug induced occlusal disorders, open bite.
