Differential diagnosis of odontophobic patients using the DSM‐IV

Abstract

Categories of extreme anxiety for dental treatment were derived using DSM-IV psychiatric criteria. A sample of 40 men and 40 women patients with extreme dental anxiety were initially evaluated with Dental Anxiety Scale (DAS), Trait Anxiety Inventory (STAI-T) and Geer Fear Scale (GFS). Patients all had DAS scores > or = 15 indicating extreme dental anxiety and were further evaluated with clinical interviews, Dental Fear Survey (DFS), Dental Beliefs Survey (DBS) and Mood Adjective Checklist (MACL). Results showed that 46% of 80 patients complained mainly of powerlessness and embarrassment about dental treatment while also having greater DBS scores than other categories, i.e. social phobia. Another 19% reported conditioned specific phobias (pain, drilling, injection, etc.) most often and lower DBS and GFS scores than other groups; while 35% had broader general anxiety complications, such as multiple phobias and agoraphobia with or without general anxiety symptoms (higher GFS and STAI-T compared to others). Symptoms of general anxiety disorder (GAD) were present in 30 of 80 patients, who had greater STAI-T and GFS and lower MACL scores than non-GAD patients. These results have implications for appropriate treatment strategies.
