Root and Canal Morphology of Maxillary Premolars in a Namibian Population: A Retrospective Cone‐Beam Computed Tomography Study

Australian Endodontic Journal, EarlyView.
ABSTRACT This study examined population‐specific morphological variations in human premolar roots and canals and their clinical implications. Cone‐beam computed tomography (CBCT) was used with the Ahmed classification system. A retrospective descriptive cross‐sectional study analysed 388 maxillary premolars from CBCT scans of 97 participants obtained ...

Is Cone‐Beam CT Reliable for Apical Foramen Assessment? A Micro‐CT–Referenced Study

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the diagnostic accuracy of two cone‐beam CT (CBCT) dose protocols for identifying the number and trajectory deviation of apical foramina. Forty lower molars were scanned in Micro‐CT. Thereafter, all teeth were inserted into the mandible sockets and a titanium implant and an endodontically treated tooth with a cobalt ...
