Name the two primary types of sedation used in dentistry.

The two primary types of sedation used in dentistry are indeed best represented by nitrous oxide sedation and intravenous sedation. Nitrous oxide, often referred to as laughing gas, is a common sedative used in dental practices to help patients relax during procedures. It is administered through a mask and allows for adjustable sedation levels, making it effective for various dental treatments.

Intravenous sedation, on the other hand, involves the delivery of sedative medications directly into the bloodstream through an IV line, providing a deeper level of sedation and allowing the dentist to closely monitor the patient's response. This method is often used for more complex procedures or for patients who experience significant anxiety regarding dental treatments.

While general anesthesia, local anesthesia, and oral sedation are important concepts in dentistry, nitrous oxide and intravenous sedation specifically pertain to the primary types focusing on managing anxiety and discomfort during dental procedures.
