A Cone Beam Computed Tomography (CBCT) in endodontic diagnosis offers several advantages in providing a detailed, three-dimensional image of the teeth and surrounding structures and a comprehensive view to enhance diagnostic accuracy. This technology allows the identification of complex anatomical variations, the extent and location of lesions, fractures or resorptions, aiding in treatment planning and prognosis determination. Moreover, CBCT reduces the need for multiple radiographs, minimizing radiation exposure for patients while maximizing diagnostic information. Overall, the utilisation of CBCT in endodontic diagnosis enhances treatment outcomes by facilitating precise diagnosis, comprehensive treatment planning, and improved patient care.
