Sedation dentistry

Sedation dentistry refers to the use of pharmacological agents to induce relaxation and often sleep in a patient prior to and during a dental appointment. It is also known as conscious sedation, where it is defined as "a technique in which the use of a drug / drugs produces a state of depression of the central nervous system enabling treatment to be carried out, but during which verbal contact with the patient is maintained throughout the period of sedation". The pharmacological agents used differ depending on patient, level of sedation desired and medical professional administering the sedation medications. The medications can belong to a class of drugs called sedatives, which exert their action by depressing the central nervous system, specifically those areas concerned with conscious awareness. Medications used to obtain sedation often include a benzodiazepine (i.e. alprazolam, triazolam, diazepam), opioids (i.e. fentanyl), dissociative (i.e ketamine) and anti-histamines (i.e. hydroxyzine, Benadryl).
