What device is used to relax patients during dental procedures?

The use of a nitrous oxide nose mask is specifically designed to help relax patients during dental procedures. Nitrous oxide, commonly referred to as "laughing gas," is administered through a mask that fits over the patient's nose. This gas produces a state of sedation, which can help reduce anxiety, discomfort, and pain perception. Its effects are quick to set in, allowing for a more relaxed experience, which is particularly beneficial in a dental environment where patients may feel apprehensive or fearful.

In contrast, an anesthetic cartridge is used to deliver local anesthesia to numb specific areas of the mouth during procedures, rather than to promote relaxation. The high-volume evacuator and low-volume saliva ejector are tools used for suctioning in the mouth, helping to keep the area dry and clear of blood or saliva, but they do not serve the purpose of patient relaxation. Thus, the nitrous oxide nose mask stands out as the best choice for promoting a calm and comfortable dental experience.
