This study aimed to develop a dental phantom with cysts for evaluation of periapical
radiographs that was tested in private dental offices in the city of Maraba, northern Brazil.
Through some tests with the object simulator (phantom) were obtained 12 periapical
radiographs (one in each of the offices visited) that waking up to the standards of Ordinance No.
453 were visually evaluated by observing the physical parameters of exposure (kVp and mA),
time revelation of the radiographic film, later the other radiographs were visually compared with
C6 ray set as the default. Among the results, it was found that only two of the twelve rays cysts
could not be viewed and, therefore, these two images were deemed unsuitable for accurate
diagnosis in the 10 images the cysts could be displayed, however according the images have
different qualities comparisons. In addition, it can be concluded that the performance of the
phantom was highly satisfactory showing to be efficient for use in quality control testing of dental
X-rays, the quality control of radiographs and continuing education of dental professionals for a
price much more accessible.
