Development of an object test to dental image verification.
An object test was developed to verify the dental images best quality in relation to the exposition time. It consists of high purity perforated aluminum plates, with different thickness and dimensions of 3x4 cm. The plates were covered by acrylic, making its total thickness of 3.0 mm. It was irradiated together with the film from 0.1 to 0.5 s. The irradiation of 0.2 s showed the best image, reducing the regular time exposition by 0.3 s.
