Abstract
Objectives: This study aimed to assess the effect of a metal artifact removal (MAR) algorithm on the visibility of the second mesiobuccal canal (MB2) of maxillary molars on cone-beam computed tomography (CBCT) scans. Materials and Methods: This cross-sectional study evaluated 41 CBCT scans of patients retrieved from the radiology clinic’s archives. The CBCT scans were saved with and without the MAR algorithm applied. The images were coded and evaluated by two endodontists to assess MB2 detection in maxillary molars and its visibility level using a 5-point Likert scale. Of the 164 samples, 32 w
