Whether used as a general anesthetic for oral surgery or as a means to provide patients with conscious sedation dentistry services, nitrous oxide has been a mainstay of dentistry for a long time. Nitrous oxide delivery systems allow you to control the mix of gas and oxygen a patient is receiving in order to provide the appropriate dose for the patient and the procedure. Some of these nitrous oxide units have digital flow controls while others are controlled manually. As with all dental equipment, nitrous oxide delivery equipment must be working properly to ensure patient safety and optimal treatment outcomes.
