What device is used to deliver nitrous oxide and oxygen during dental procedures?

The device used to deliver nitrous oxide and oxygen during dental procedures is the nitrous mask. This mask is specifically designed to fit comfortably over the patient’s nose and/or mouth, allowing for the inhalation of a controlled mixture of nitrous oxide and oxygen, commonly referred to as "laughing gas." This sedation method helps to relax patients and reduce anxiety during dental treatments.

The nitrous mask is essential for ensuring effective and safe delivery of the sedative, allowing the dental professional to manage the concentration of gases the patient receives. It is important for maintaining patient comfort and cooperation during procedures that may otherwise cause tension or discomfort.

Other devices mentioned serve different purposes. An anesthetic syringe is used for administering local anesthetics to numb specific areas in the mouth rather than for sedation. A cotton roll holder is designed to hold cotton rolls in place for moisture control and tissue management, and a rubber dam clamp is part of the isolation system used to keep the operative field dry and clear of saliva and debris, facilitating better visibility and access for the dentist. Each of these tools has its unique role, but none are used for the delivery of nitrous oxide and oxygen.
