Endodontics (root canal treatment) is considered to be one of the most complex treatments in dentistry, including also implantation of teeth. After all, the shape and number of teeth are as individual as fingerprints. Roots of the tooth of some patients are straight and short, but someone has long and curved roots. In the same tooth one person may have two channels and the other - five. It is difficult to determine the amount of canals only using intra-oral X-ray image. For diagnosis of any root diseases Endodontists in Oregon use computer tomography, which allows more accurate and reliable diagnosis. 3D-images allow high accuracy in identifying location, number, and shape of root canals.
