Accuracy of a 3D Intraoral Scanner in Endodontics

Year: 2026

Type: article

Abstract: This study measured the accuracy of an intraoral scanner (Primescan, Dentsply Sirona, Charlotte, NC, USA) in examining endodontic access openings. The method was compared to the clinical microscope and CBCT. Primescan scanned the pulp chambers of 24 extracted molars shortly after access, and the computer-3D models were inspected to document the orifices (number; location) and chamber features (calcifications; defects originated during access; anatomical variations). Scanner agreement to identify the orifices' number and location was non-significant in relation to both the microscope and CBCT; considered, therefore, accurate. It was also accurate to show defects (bur abrasion) and/or anatomical features (isthmus) in the chamber floor, with diagnostic accuracy estimated in 87.5% (95% CI: 67.6-97.3) in relation to the microscope. Scanner diagnostic accuracy to show calcified orifices was estimated in 79.2% (95% CI: 57.8-92.9) in relation to the microscope, and 70.8% (95% CI: 48.9-87.4) in relation to the CBCT, considered, then, of moderate accuracy.
