Mani Lentulo Spiral(Paste Carrier) often referred to simply as a Lentulo Spiral or Paste Carrier, is a specialized dental instrument used extensively in endodontic procedures. Its primary purpose is to facilitate the precise placement of root canal filling materials within the intricate and narrow root canal system of a tooth. The Lentulo Spiral is designed with a slender, spiral-shaped configuration, making it well-suited for navigating the complex root canal anatomy. It is typically attached to a slow-speed handpiece, which provides dental professionals with control over its rotation. After the root canal is carefully prepared and cleaned, the Lentulo Spiral is employed to deliver and distribute root canal filling materials, such as sealer or cement, into the canal. By slowly rotating the Lentulo Spiral, dentists can ensure that the filling material is evenly spread along the inner walls of the root canal. This precise placement is crucial for achieving a hermetic seal and preventing bacterial re-infection. Proper training and expertise are essential when using this instrument to avoid potential complications and optimize the success of endodontic treatments.
