We report a case of dental therapy on a patient with an abnormal personality who had an extreme phobia of dental treatment, in which treatment was performed smoothly under intravenous sedation with propofol.
The patient was a 21-year-old woman. Har mother had a history of schizophrenia, and she had a diagnosis of abnormal personality. She routinely used diazepam, amitriptyline, lormetazepam, and viamin A. The patient was introduced to the Department of Dental Anesthesiology, Nihon University School of Dentistry, because of the breakage of a maxillary anterior tooth crown.
The patient was very unstable emotionally at the time of referral, and complained of an extreme phobia of dental therapy. Oral examination revealed the need for tooth extraction, pulpectomy, and placement of a new crown. Since she was receiving the aforementioned drugs, intravenous sedation was scheduled to be performed. During the first session of intravenous sedation, dental therapy was performed smoothly under a propofol dose of 6 to 10 mg/kg/min. Two subsequent sessions of intravenous sedation were performed, and the dental thrapy was completed without any problem. The patient's trust gradually increased.
