Impact of case complexity on paediatric dentists' ability to radiographically diagnose traumatic dental injuries

BACKGROUND/AIMS: Being able to correctly interpret radiographs after a traumatic dental injury is an essential skill for providing appropriate and timely treatment. The aim of this study was to assess the impact of case complexity on paediatric dentists' performance when radiographically diagnosing traumatic dental injuries (TDI) and to investigate a possible added value of cone-beam computed tomography (CBCT) when compared with digital intra-oral radiography (2D vs 3D). MATERIALS AND METHODS: A test panel of paediatric dentists was instructed to detect, identify and interpret radiographic findings using either 2D or 3D images. Intra-oral radiographs and CBCT images of 20 trauma cases were presented in random order, and the findings were recorded using structured scoring sheets. Case complexity was determined by two experienced benchmark scorers. Results were analysed using generalized linear mixed modelling. RESULTS: In general, performance for detection, identification and interpretation of findings was low, both with 2D and 3D images, with significantly lower values for difficult cases (p < 0.05). For easy as well as for difficult cases, 3D imaging resulted in a significantly better performance for detection and identification of findings (P < 0.001). This was not the case for correct interpretation, where significantly poorer performance was seen when using 3D images for difficult cases (p < 0.05). CONCLUSION: This study provides evidence that case complexity of traumatic dental injuries influences diagnostic performance. The use of CBCT enhanced detection and identification of findings but when case complexity increased, 3D imaging adversely affected correct interpretation.
