AVALIAÇÃO DOS ERROS RADIOGRÁFICOS COMETIDOS POR ALUNOS DE GRADUAÇÃO DURANTE O TRATAMENTO ENDODÔNTICO EVALUATION OF THE RADIOGRAPHIC ERRORS PERFORMED BY UNDERGRADUATE STUDENTS DURING ENDODONTIC TREATMENT

Introduction: The aim of this study is to evaluate the radiographic errors performed by undergraduate students during the endodontic treatment. Methods: A total of 260 periapical radiographs were divided in these: groups initial radiography, length tooth, try-in of gutta-percha point, corroborative of the lateral condensation e final radiography. The radiographs were obtained employing the same kind of film (E-speed, Kodak) and of X-Ray units (50KV, 7,5mA), with a 0,8-second exposure time, and they were processed by visual method. With help of a magnifying glass and a viewbox, three examiners analyzed the radiographs and registered errors related to technique and processing. Results: The results showed that 57,70% of the radiographs analyzed exhibited some kind of errors (technique errors or processing). There were not significant differences in the number of the errors in the different phases of endodontic treatment. Conclusion: The highest frequency of errors was seen in radiograph processing (stains, presence of splines and inadequate radiographic density).
