The preparation of a post space requires precision and caution to avoid damaging the already obturated root canal. The Pesso Reamer, often interchangeably called a Glidden Drill, is the instrument of choice for this delicate task. This essential 6-piece set, encompassing sizes 1 through 6, provides the dentist with the complete range needed to safely and efficiently create space for a prefabricated post.
These drills feature a long, slender shaft with a short, safe-ended (non-cutting) tip and a blunt nose design. This safety tip is critical as it helps prevent perforation or gouging of the root dentin during preparation. The cutting flutes are designed to remove gutta percha and sealer cleanly while minimizing the risk of ledging or transporting the canal. They are intended to be used in a slow-speed handpiece with a gentle pecking motion, following the path of the existing canal.
Manufactured from high-quality surgical stainless steel, these reamers are built for durability and sharpness. Each size is color-coded for instant recognition, and the set typically comes organized in a convenient rack or case for storage and sterilization. The sequential sizes allow for gradual, controlled widening of the canal to the desired diameter for the selected post system.
This set is an indispensable part of the restorative armamentarium. By using these purpose-designed instruments, clinicians can efficiently prepare post spaces while conserving root structure and maintaining the integrity of the seal, ensuring a solid foundation for the final coronal restoration.
