Association between bacterial load and volumetric bone loss in teeth with persistent apical periodontitis: A cone-beam computed tomography segmentation-based observational study.
AIM To quantitatively compare the bacterial DNA load in root apices and periapical lesions surgically retrieved from teeth with failed root canal treatment, and to investigate the association between bacterial DNA load in both anatomical locations and the three-dimensional (3D) volumetric extent of periapical bone loss...
