Final Answer:
A Lentulo Spirals is used in a low-speed handpiece to place sealer and cements into tooth canals during root canal therapy (RCT). Thus the correct option is C) Lentulo Spirals.
Step-by-step explanation:
In root canal therapy (RCT), Lentulo Spirals are used in a low-speed handpiece to precisely place sealer and cements into tooth canals. These spirals are slender instruments designed for this specific purpose and facilitate the effective application of materials within the intricate and narrow root canal spaces.
Lentulo Spirals are particularly advantageous for delivering sealers and cements due to their helical design. The spiral shape enables the controlled and uniform distribution of these materials along the canal walls. This ensures thorough coverage and effective sealing of the root canal system, contributing to the success of the root canal therapy.
The choice of Lentulo Spirals over other options like broaches, reamers, or files is rooted in the specific requirements of the task. While each instrument serves a distinct purpose in dental procedures, Lentulo Spirals are tailored for the precise application of sealers and cements in root canal therapy, providing dentists with a reliable and efficient tool for this crucial aspect of the procedure.
Therefore, the correct option is C)Lentulo Spirals
