General anesthesia or sedation is an essential for a successful dental treatment for the disabled. The aim of this study is to assess the patients who had dental management under general anesthesia or sedation at Chungnam dental clinic for the disabled, who received dental treatment under general anesthesia, sevoflurane sedation and intravenous sedation from January, 2011 to September 2012. Of the 426 patients studied, 389 patients received dental care under general anesthesia, 20 patients received dental care under sevoflurane sedation and 17 patients received dental care under intravenous sedation. The Rate of general anesthesia was higher than that of sevoflurane sedation, intravenous sedation. Sevoflurane sedation is a useful method for short time treatment such as traumatic pediatric patients. Intravenous sedation is an option for patients who had anxiety and fear such as dentally disabled patients. Sevoflurane or intravenous sedation not only gradually reduces the use of general anesthesia but also useful methods themselves for the dentally disabled.
