Half of the sample of each group was selected for the induction of vertical root fractures. Each tooth was placed in an empty socket of a dry skull which was scanned on a CBCT unit (9000 3D scanner; Kodak Dental Systems, Carestream Health, Rochester, NY, USA) using the following exposure parameters: 74\u00a0kV\/12\u00a0mA; 74\u00a0kV\/10\u00a0mA; 74\u00a0kV\/8\u00a0mA; 74\u00a0kV\/6.3\u00a0mA; 70\u00a0kV\/12\u00a0mA; 70\u00a0kV\/10\u00a0mA; 70\u00a0kV\/8\u00a0mA; 70\u00a0kV\/6.3\u00a0mA. Two observers assessed all images using a 5\u2010point confidence scale for fracture detection and a 4\u2010point score for the presence of artefacts. Sensitivity, specificity, accuracy and area under ROC curve were compared by two\u2010way <jats:sc>anova<\/jats:sc> and Tukey's test. Artefact formation was evaluated by descriptive statistics.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were no significant differences in the sensitivity (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.370), specificity (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.660), accuracy (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.084) and area under the ROC curve (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.674) values amongst the various exposure parameters within the same group. There were some significant differences when the groups were compared for each intracanal material. The sensitivity and accuracy of the group containing metallic posts were significantly lower than the unrestored and fibreglass post groups (<jats:italic>P<\/jats:italic>\u00a0\u2264\u00a00.017).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The variations in exposure parameters did not interfere with the diagnosis of vertical root fractures, independent of the root canal restorative status. Metallic posts were associated with greater artefact formation and compromised the diagnostic performance. It is possible to decrease the kVp\/mA settings to reduce the probability of biological effects due to radiation, without losing diagnostic accuracy.<\/jats:p><\/jats:sec>","DOI":"10.1111\/iej.12655","type":"journal-article","created":{"date-parts":[[2016,5,2]],"date-time":"2016-05-02T01:05:04Z","timestamp":1462151104000},"page":"586-594","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":58,"title":["Influence of exposure parameters on the detection of simulated root fractures in the presence of various intracanal materials"],"prefix":"10.1111","volume":"50","author":[{"given":"M.
