What is the primary tool used to remove excess cement in orthodontic procedures?

The primary tool used to remove excess cement in orthodontic procedures is the explorer. This instrument is specifically designed with a pointed end that allows dental professionals to accurately detect and remove any excess cement that may be left after bonding brackets or other orthodontic appliances. The explorer's design makes it suitable for accessing tight spaces around the teeth and appliances, ensuring that any residual material can be effectively cleared away, which helps prevent potential issues such as plaque accumulation or irritation of gum tissue.

Other tools listed, such as a scalpel, are more suited for cutting soft or hard tissue rather than precise removal of cement. An excavator is generally used for removing dental caries or debris from the cavity in restorative dentistry, not specifically for the purpose of cleaning up after orthodontic cement. The U15, often referring to a specific type of periodontal scaler or an instrument designed for particular tasks related to subgingival scaling, does not primarily serve the purpose of managing excess cement in orthodontic contexts. Thus, the explorer is the ideal tool due to its functionality and precision in such situations.
