The 6-Piece Pesso Reamer and Glidden Drill Set comprises specialized, long-shank rotary instruments used in post space preparation within endodontically treated teeth and for orifice opening during root canal treatment.
Technical Specifications & Material Science: These are latch-type (RA/Latch) rotary instruments designed for use in a low-speed handpiece. They are made from stainless steel and have a non-cutting, guiding tip to follow the existing gutta percha or canal path. The cutting flutes are along the shaft. Pesso Reamers (often #1-3) are longer and used specifically for preparing space for a prefabricated post (e.g., fiber or metal) by removing gutta percha and dentin from the coronal portion of the canal. Glidden Drills (#1-6) are shorter and used primarily for orifice enlargement and shaping of the coronal third of the canal to improve straight-line access. Each size corresponds to a specific diameter, increasing sequentially.
Industry Standards & Compliance: Standard endodontic rotary instruments.
Application Scenarios:
- Post and Core Fabrication: After a root canal, to create a space for a post that will retain a core buildup for a crown.
- Coronal Flaring: The initial step in many rotary file systems to remove cervical constrictions and allow smoother instrument progression apically.
Usage Guidelines: Used at very low speeds (300-600 RPM) with a pecking motion and copious irrigation. The depth is carefully controlled to leave at least 4-5mm of apical gutta percha seal. The drills are used in sequential order from smallest to largest to avoid binding and perforation.
Market Value Proposition: This set is essential for any practice performing post-retained restorations. It is a fundamental part of the core buildup procedure. For suppliers, offering a complete #1-6 set ensures the clinician has the right tool for any case, from narrow canals to large ones. These are durable, reusable items that are part of the practice’s core instrument inventory.
