What is lentula used for in dentistry?

1. A tool for measuring dental depth

2. A flexible spiral-wire instrument

3. A type of dental anesthesia

4. A method for treating gum disease

The correct answer is: A flexible spiral-wire instrument

Lentula is indeed a flexible spiral-wire instrument commonly used in dentistry, particularly in endodontics. Its primary function is to help facilitate the filling of root canals by enabling the insertion and distribution of sealers, pastes, or gutta-percha. The spiral design allows for effective material delivery and helps ensure that the chosen filling material is evenly distributed within the canal, minimizing voids and ensuring a proper seal. The other options refer to different dental tools or methods that serve distinct purposes in dental practice. For instance, measuring dental depth is crucial in various procedures, but it would not involve the use of lentula. Similarly, dental anesthesia relates to pain management during procedures and is administered through syringes or other drug delivery systems, not through spiral instruments like lentula. Lastly, methods for treating gum disease typically involve scaling, root planing, or other periodontal therapies, which also do not utilize lentula. Understanding the specific role of lentula in the context of endodontic procedures solidifies its importance in ensuring successful outcomes in root canal therapy.
