The Carestream CS 9600 tomograph was used, testing 2 experimental models (presence and absence of adjacent metallic objects), with tube voltages of 100\u2009kV and 120\u2009kV, voxel sizes of 75 and 150\u2009\u00b5m, and applying the metal artefact reduction (MAR) filter. Three examiners scored according to the Likert scale. The Fleiss\u2019 kappa test was performed to analyse intra- and inter-examiner agreement, in addition to Cochran\u2019s Q test with a significance level of 5%, to compare the parameters of tube voltage, voxel size, and MAR filter.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The Fleiss\u2019 kappa test showed excellent inter- and intraobserver agreement for all groups. All modalities of tube voltage, voxel size, and MAR filter showed very high accuracy, sensitivity, and specificity, providing diagnoses consistent with reality, achieving 99% accuracy when the model did not present adjacent metallic objects to the tooth, and 95% accuracy when such objects were present.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
