Psychiatrists' and dentists' knowledge and attitudes regarding adverse drug reactions of psychotropic drugs.

Psychotropic drugs may induce impairments in the mouth, jaw and face area. Currently, appropriate pharmacoepidemiologic data are missing. Therefore, a questionnaire-based telephone survey of two non-representative samples of psychiatrists and dentists was conducted. Most of the psychiatrists (79.7%) and dentists (76.5%) indicated that psychotropic drugs may induce dental adverse drug reactions (ADR); in both samples there was an approximately equally sized, relevant proportion of participants who did not believe in the risk of dental ADR of psychotropic drugs (psychiatrists 20.3%; dentists 23.5%). About one third of the participants of both samples (psychiatrists 34.9%; dentists 35.9%) felt that dental ADRs of psychotropic drugs are a serious health problem. The majority of both groups (psychiatrists 97.8%; dentists 97.0%) had never reported a dental ADR. Most psychiatrists and dentists appeared to be aware of the risk of dental ADRs by psychotropic drugs. A relevant proportion of participants of both groups considered psychotropic drugs to be irrelevant regarding dental ADRs; therefore, there may be information needs in both groups. The willingness to report dental ADRs of psychotropic drugs was low in both groups; the evaluation of the actual relevance of this drug-related risk is impeded by the absence of reports of suspected ADRs.
