Optical Coherence Tomography (OCT) is a non-invasive diagnostic technique that utilizes near infrared light to image biological tissue microstructures. Previous research by current authors has shown the potential of OCT as an instrument to provide detailed information about the internal root canal without exposure to radiation. This study was set up to confirm the efficacy of the OCT using a catheter-based imaging probe for detection of intact dentin and modifications within root canals. Dental anomalies or areas of interest for imaging were selected to be internal resorption, vertical root fracture, horizontal root fracture, lateral canal, and bifurcation. This project used the St. Jude/Abbott OPTIS Integrated System, Dragonfly OPTIS Imaging Catheter, dental microscope, extracted teeth with single canals, a vacuum base vise, and handfiles. 11 teeth were selected via inclusion criteria and underwent preparation to simulate anomalies, followed by root canal analysis using OCT. This study determined (1) the minimal apical diameter of 0.9mm needed to fit the OCT catheter to the apex (2) confirmed consistency of method with repeated use, (3) verified presence of simulated anomalies, and (4) established continued functionality after alteration of catheter. In conclusion, OCT has the potential to be a viable diagnostic tool in endodontics. / 2026-06-24T00:00:00Z
