Evaluation of Brasseler USA XP-3D Shaper and Its Effect on Apical Foramen Size
Abstract
Adequate working length (WL) and minimal enlargement of the apical foramen are important for successful endodontic outcomes 1,2. Even though procedural errors, such as unintentional enlargement of the apical foramen, are not the direct cause of treatment failure, they can potentially cause a treatment failure or diminished long-term prognosis. It has been suggested that enlargement of the canal to 3 sizes larger than the first apically binding file is sufficient and additional enlargement of the canal will not cause any further benefits 3. Additionally, some even suggest that no apical enlargement is necessary in order to achieve proper disinfection of the root canal system 4. Introduction of rotary nickel-titanium (NiTi) files and their constant improvement had allowed to minimize procedural iatrogenic errors and better control over cleaning and shaping procedures. Advancements in metallurgy allowed for introduction of multiple new instrumentation systems and single files that claim to perform fast, accurate and adequate cleaning and shaping of the root canal systems without excessive enlargement of the apical foramen 5,6. Brasseler XP-3D Shaper is a new rotary file with adaptive core design that allows it to conform to canal morphology ranging from size no. 30 to no. 90 at a .02 to .08 taper. The instrument is designed so when it rotates, its orbit expands and contracts to equally abrade the broad and narrow aspects of the canal as it continually adapts to the canals anatomy 7. Research indicates that when using the XP-3D Shaper, the final taper of the canal will indeed vary according to the original size and shape of the root canal system 8,9. In addition, XP-3D shaper was evaluated when used at the foramen and was found to enlarge but not deform the apical foramen 10.
