Tomography and Cbct : an overview

CT and CBCT scan technologies have played a major role in the evolution of diagnostic imaging for dental applications. The ability to visualize each individual patient's anatomy with an interactive 3D assessment takes the guesswork out of the equation, and allows clinicians to make truly educated decisions regarding treatment. Using the ALARA principle, newer CBCT imaging machines have achieved the delivery of this information with a significant reduction in radiation, and smaller in-office machines that provide almost instant access to enhanced diagnostic imaging. When compared with medical CT, CBCT has increased accuracy, higher resolution, reduced scan time, a reduction in radiation dose, and reduced cost for the patient. This book gives an overview about CBCT and its applications, advantages and limitations in dentistry.
