Conscious sedation and general anesthesia have been in the use of the dental profession since the first half of the 19th century. Although seemingly appealing to use due to alleviation of pain and anxiety induced by the dental treatment, the alteration of consciousness level of dental patients is not without risk. Morbidity and mortality due to dental treatment performed under general anesthesia were investigated at the last decades of the 20th century. The mortality rates found in these investigations were surprisingly high comparing to researches of morbidity and mortality due to other medical procedures, performed under general anesthesia. Therefore, although general anesthesia is sometimes the only way to treat certain patients, maintaining strict indications for dental treatment under general anesthesia is necessary. Conscious sedation was found as a safer alternative for achieving a level of consciousness enabling dental treatment in those patients who are unable to receive treatment in normal dental clinic settings. We therefore believe that conscious sedation should be the golden standard for the treatment of those patients. The practicing of dentistry in patients who have need of dental treatment under special settings such as general anesthesia and sedation raises ethical dilemmas to the caregiver. The following review will summarize the available data on morbidity and mortality due to dental treatment given under general anesthesia and conscious sedation. The ethical questions arising from their practicing will be discussed and some answers shall be proposed.
