Description
GemDent Paste Carriers (Lentulo): High-Efficiency Sealer Distribution
The GemDent Lentulo Spiral is a precision-engineered rotary instrument designed for the rapid and thorough application of root canal sealers, cements, or calcium hydroxide pastes. Ground from high-flexibility stainless steel, these carriers feature a specialized conical spiral that prevents air bubbles and ensures a void-free coating from the orifice to the apex.
Designed for use with a Low-Speed Handpiece (Torque Series), the GemDent Lentulo provides the mechanical consistency required for a dense, predictable obturation.
📐 The "Spiral Spring" Advantage: Engineered for Flow
The GemDent Lentulo features a Tapered Spiral Cross-Section, offering distinct clinical advantages for material delivery:
-
Centrifugal Material Loading: As the spiral rotates, it creates a centrifugal "pumping" action that drives the sealer toward the canal walls and into lateral canals that manual plugging cannot reach.
-
Anti-Air Bubble Geometry: The continuous spiral design ensures that material is fed forward constantly, displacing air coronally and preventing the formation of "voids" in the final fill.
-
High-Flexibility Safety Spring: The base of the instrument features a safety spring (the "shock absorber") that allows the carrier to navigate moderate canal curvatures without snapping or locking into the dentin.
-
Uniform Film Thickness: By providing a consistent rotational speed, the Lentulo ensures the sealer is applied in a thin, even layer—ideal for seating Gutta Percha points without excessive hydraulic back-pressure.
⚙️ Key Performance Features
-
Break-Resistant Stainless Steel: High-tensile alloy designed to withstand the rotational stresses of a low-speed motor (recommended 300–600 RPM).
-
Conical Spiral Taper: Matches the natural anatomy of the prepared canal, ensuring the widest part of the spiral coats the coronal third while the tip reaches the apex.
-
ISO Color-Coded Shanks: Standardized coloring for immediate size identification to match your final shaping file.
-
Safety Handle Design: Specifically weighted for use in latch-type (RA) contra-angle handpieces.
-
Fully Autoclavable: Durable construction designed for repeated clinical use and high-temperature sterilization.

🛠️ Clinical Applications
-

-
Medicament Placement: Delivering Calcium Hydroxide for inter-appointment disinfection.

Cementation: Applying resin-based cements for fiber post-placement.
💡 Clinical Tip: The "Spin-Out" Technique
To avoid "over-filling" or pushing sealer past the apex, always insert the Lentulo while it is stationary, then start the motor once you are at the working length. Most importantly, always keep the instrument rotating as you withdraw it from the canal. This ensures the spiral continues to pull material toward the walls rather than leaving a "clump" at the orifice.
