most mandibular second molars have one and two canals in distal and mesial roots, respectively. this report represents four cases of mandibular second molars with a single mesial and two distal root canals with two different canal configurations. after access cavity preparation, two teeth had one distal and two mesial orifices, whereas in the two other teeth one mesial and two distal orifices w...
RATIONALE Cone Beam Computed Tomography imaging has become increasingly important in many fields of interventional therapies. OBJECTIVE Lung navigation study which is an uncommon soft tissue approach. METHODS As no effective organ radiation dose levels were available for this kind of Cone Beam Computed Tomography application we simulated in our DynaCT (Siemens AG, Forchheim, Germany) suite ...
A comparison of image quality and dose delivered between two differing computed tomography (CT) imaging modalities-fan beam and cone beam-was performed. A literature review of quantitative analyses for various image quality aspects such as uniformity, signal-to-noise ratio, artifact presence, spatial resolution, modulation transfer function (MTF), and low contrast resolution was generated. With...
Cone beam computed tomography is a comparatively new threedimensional imaging technology, which has been specially developed for imaging of the maxillofacial complex. The aim of this paper is to accustom the dental fraternity with the wide and potential applications of cone beam computed tomography in dentistry.
