Two calibrated endodontists independently assessed the mesiobuccal (MB), distobuccal (DB), and palatal roots for the presence of PCO in sagittal, coronal, and axial planes using CBCT (&lt;0.2 mm voxel size). Inter- and intra-observer reliability was evaluated using Cohen\u2019s kappa. Associations between caries location and PCO were analyzed using Pearson\u2019s Chi-square test or Fisher\u2019s exact test and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      PCO was observed in 21.2% (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 34\/162) of maxillary molars.
