Pain associated with dental treatment is managed effectively through the administration of local anesthetic drugs prior to the start of treatment. These chemicals prevent passage of the nerve impulse beyond the site at which they are received. Although the tooth or soft tissues have recieved a noxious stimulus, the nerve implulse will stop at the site where the local anesthetic drug was deposited. The action potential on the nerve axon is blocked, the impulse is terminated and the patient feels no discomfort.
Dental anxiety can be managed by inducing a state of consciousness (or, more precisely, altered consciousness) in which a person is more relaxed and carefree than previously. Over the years many names have been given to this state. Names such as chemamnesia, sedamnesia, twilight sleep, relative analgesia and comedication have been used to describe the state of consciousness that is now called sedation.
