MACIEIRA, Mônica Martins et al. Differential radiographic diagnosis of internal and external root resorptions between endodontic specialists and general practitioners. RFO UPF [online]. 2011, vol.16, n.3, pp. 273-276. ISSN 1413-4012.

Objectives: The objective of this study was to evaluate the ability of endodontists and general practioners to perform the differential radiographic diagnosis between internal and external root resorptions, using digitized periapical radiographs. Methods: Thirty periapical radiographic images of external and internal resorption were selected. The evaluators were comprised of 15 endodontists and 29 general practitioners who answered a questionnaire with the following question: "What type of resorption in the following radiographics do you diagnose?" (1) Inflammatory external root resorption. (2) Internal root resorption. Statistical analysis was performed based on the Mann-Whitney test, with significance level of 5%. Results: There was no statistically significant difference in the percentage of correct answers from specialists in endodontics and general practitioners. Conclusions: Both groups demonstrated satisfactory skill in the radiographic interpretation of internal and external resorption and there was a higher percentage of correct diagnosis of internal resorption than the external.
