 note = {application/pdf, We analyzed the dental patients treated with psychosedation in the Department of Dental Anesthesiology, Matsumoto Dental University Hospital over the past 14−year period on the clinical records and anesthesia records. Of a total of 2802 patients, 2285 were treated on an outpatient basis and 517 were hospitalized for treatment. As for age distribution, the age group of 20−29 years old was the most dominant, while gender distribution was 46% males and 54% females. Psychosedation was performed most often for ‘minimizing stress related to systemic illness’ (n=992), followed by ‘fear of highly−invasive dental treatment.’ When divided by the type of sedative therapy, treatment was given as intravenous sedation in 2035 patients, nitrous oxide inhalation sedation in 740 and combined (intravenous−inhalation) sedation in 27. The agents used for intravenous sedation were midazolam in 887 and flunitrazepam in 856 patients. The clinical departments where sedation was given to patients varied, though the Department of Oral Surgery was predominant with 73% of the patients (n=2055). We also found that the number of psychosedation cases were showing an increasing trend, as the number of patients in 2011 was approximately 4 times greater than in 1998. As reasons for that increase, we consider that psychosedation has become more well known by both clinicians and patients, and that the prevalence is increasing along with the aging of society in Japan. As for the type of sedation, the ratio of intravenous sedation cases was high, which is likely because a sedative effect can be reliably obtained with a greater level of sedation than nitrous oxide inhalation sedation. At our institution, a predominant num- ber of sedation cases were treated in the Department of Oral Surgery, with tooth extraction the most common procedure requiring a sedative. We speculated that this department performs highly invasive treatments, such as tooth extraction, as compared to others and that high−risk patients with systemic illness were often referred by practitioners in other departments.},
