What does the Lentulo spiral drill do?

1. It shapes the root canal

2. It spreads calcium hydroxide or cement into a root canal

3. It removes decay from the tooth

4. It extracts teeth effectively

The correct answer is: It spreads calcium hydroxide or cement into a root canal

The Lentulo spiral drill is specifically designed to aid in the application of calcium hydroxide or cement into the root canal. This instrument features a helical design that allows for the efficient delivery of material to the treated area, ensuring that the medication or sealing material can coat the inner surfaces of the root canal effectively. The Lentulo drill's ability to distribute materials uniformly is crucial during endodontic procedures, as it helps to facilitate the healing process and to seal the root canal system properly, minimizing the risk of reinfection. This functionality distinguishes it from other dental instruments that have different purposes. While shaping the root canal, removing decay, and facilitating extractions are essential aspects of dental procedures, they are performed by other specific tools and instruments tailored to those tasks. Therefore, the role of the Lentulo spiral drill is uniquely centered around the application of substances that support the health and integrity of the root canal, making the correct answer B.
