Sedation dentistry is basically the application of soothing tactics like anesthesia to keep patients relaxed during the usually painful act of dental treatment and repairs. People having dentistry phobia, especially children and those required to be in the treatment seat for prolonged periods of time are the ones who are put under sedation by dentists. Sedation does not really mean total sleep, but in dentistry, it is a process of putting the patients under a trance to assuage fear, pain or any uncomfortable feeling.
The dentist determines the level and type of sedation required for a patient before starting the treatment procedure. Some are administered intravenous drugs for deep sedation, but most patients require moderate sedation only with oral sedatives, nitrous oxide etc.
People with dental phobia dread visiting the dentist, his office and even the tools. Even in case of dire situations they try to postpone the session with the dentist. On the other hand, some suffer form dental anxiety, which is a lesser form of dental phobia. Whatever may be the condition both categories of people are at the losing edge, since they hesitate to avail the services of a dentist. The result would be poor dental health. Most of the time children are taken to the dentist by force against their wishes.
Sedation dentistry helps such people to be kept in check and relaxed throughout the treatment process. Oral sedatives are enough to sooth the nerves of patients if the process is of shorter durations. But they are not pain relievers and a local anesthetic is usually injected for the purpose. The same is the case with intravenous sedation and inhalation sedation too. If the process is time consuming and tiresome, general anesthesia is applied to keep the patient unconscious. Since the patient is totally out of senses, local anesthetic is not needed at all.
The effect of these sedation dentistry tactics differs from person to person. Nitrous oxide gas, or laughing gas, is best suited for anxiolysis or light sedation. Moderate sedation can be achieved by an intravenous sedative. In both the cases, the patient would be awake. Deep sedation brings about a state between unconsciousness and consciousness and the patient is extremely relaxed but able to respond to commands. Very deep sedation or unconsciousness is achieved by applying anesthesia and is used usually while performing oral surgeries.
