This document discusses the use of dentascan imaging in endodontics. It provides an overview of the limitations of conventional 2D imaging techniques for assessing root canal morphology and the extent of periapical infections. Dentascans provide 3D imaging which allows evaluation of anatomy in all three dimensions through various reformatted views. A case report demonstrates how dentascans identified extra canals and the full extent of periapical infection and bone loss not visible on 2D imaging. While effective, dentascans have limitations including cost and radiation dose. The document concludes dentascans can improve endodontic treatment outcomes by providing a more accurate assessment of root canal anatomy and periapical pathology.
