Zhang W, et al. - Authors compared and correlated accuracy of molar furcation assessment via clinical detection, intraoral radiography and cone beam computed tomography (CBCT) images. Data suggested that in addition to clinical detection and intraoral radiography, CBCT was a valuable tool in molar furcation assessment. Experts noted higher correlation of CBCT with clinical detection relative to intraoral radiography, especially at distal palatal side of maxillary first molar. Also, more accurate assessment was provided by CBCT, with bone loss measurement up to 2 decimals in millimeters, whereas clinical detection had 3 classes and usually the intraoral radiographs only detected the presence of furcation involvement in Glickman Class 2 and 3.
