Abstract
BackgroundThe aim of this study was to assess the diagnostic accuracy of various dentoalveolar pathologies based on panoramic radiography (OPG), cone beam computed tomography (CBCT) and printed 3D models in consecutive order; and to evaluate the impact of specialisation of residents in oral surgery (OS) versus residents in orthodontics (ORTH).MethodsFourteen residents were recruited to evaluate nine selected cases with different dentoalveolar pathologies. The residents were given for each case an OPG, a CBCT and a printed 3D model. For each case and imaging modality, the residents were asked several questions relating to (i) diagnosis, and (ii) the request for consecutive imaging in order to enable treatment. Further, aspects like impact of specialisation (OS versus ORTH), gender and years of experience were analysed.ResultsIn this study, diagnostic accuracy (i) improved for OS from OPG to CBCT (OPG 66.3%, CBCT 83.4%) and likewise for ORTH (OPG 63.7%, CBCT 78.0%). 3D models generally did not seem more useful than CBCTs. For treatment planning (ii), residents in orthodontics considered OPGs significantly more often as sufficient compared to residents in oral surgery (OR 6.3, p < 0.001). Further, the odds to request a CBCT after OPG for treatment planning is influenced by dentist-related factors: female dentists (OR 3.8) or residents with limited professional experience as dentists (OR 3.0) asked more frequently for a CBCT.ConclusionsOverall diagnostic accuracy is decent with OPG and can be improved with CBCT. Specialisation seems to have a moderate impact on diagnostic accuracy, but influences whether a CBCT was requested for treatment planning. Based on these findings, future studies shall analyse the diagnostic accuracy of specific pathologies in higher number in order to substantiate the present findings with regard to specific pathologies.
Highlights
The aim of this study was to assess the diagnostic accuracy of various dentoalveolar pathologies based on panoramic radiography (OPG), cone beam computed tomography (CBCT) and printed 3D models in consecutive order; and to evaluate the impact of specialisation of residents in oral surgery (OS) versus residents in orthodontics (ORTH)
According to most prevailing guidelines [7,8,9], three-dimensional imaging is recommended for patients who will benefit from cone beam computed tomography (CBCT) because the diagnosis would otherwise remain uncertain or the treatment plan unclear
The aim of this study was (i) to assess whether pathologies are accurately diagnosed in three different imaging modalities (OPG, CBCT, 3D model) of the same case, and (ii) whether the case is classified as treatable on the basis of the present imaging modality
Summary
The aim of this study was to assess the diagnostic accuracy of various dentoalveolar pathologies based on panoramic radiography (OPG), cone beam computed tomography (CBCT) and printed 3D models in consecutive order; and to evaluate the impact of specialisation of residents in oral surgery (OS) versus residents in orthodontics (ORTH). While the guidelines are hardly disputed, it must be noted that diagnostic accuracy and the effect on patient management (such as setting a treatment plan) are two different facets of imaging efficacy and have historically always been viewed in a hierarchical order [10, 11]. While diagnosis of a pathology should clearly remain unaffected by the dental specialisations, the treatment plan may differ between disciplines. The evaluation of a CBCT scan should preferably include the impact on diagnostic accuracy as well as treatment approach
