________ have a cutting tip used to assess the sectioning of teeth.

• A. Luxators
• B. Elevators
• C. Chisels
• D. Rongeurs

Answer: (A)

The key idea is that certain dental instruments are built for precision cutting at the tooth’s attachment to the bone. A luxator features a very thin, sharp blade at its tip that is specifically designed to cut through the periodontal ligament with controlled, minimal trauma. This cutting action is what allows the tooth to be luxated and, when needed, sectioned with minimal resistance. That cutting capability makes it the best choice for initiating and assessing sectioning of teeth, especially when dealing with multi-rooted teeth. Elevators mainly rely on leverage to loosen a tooth and don’t have a specialized cutting edge, chisels are used for enamel work or stronger splitting tasks rather than delicate ligament severing, and rongeurs are for removing bone.
