Resumo


The introduction of digital radiography marked a significant advancement in dentistry starting in the 1980s, with the emergence of the first intraoral digital radiographic imaging systems. This technology revolutionized diagnostic imaging exams, presenting itself as a beneficial alternative to conventional radiology.(1, 2) In digital radiography, the image acquisition process is similar to the conventional technique, with the main difference being the image receptor: instead of traditional film, a digital sensor is used. There are three methods of acquiring digital radiographic images: indirect, semi-direct, and direct. The indirect method involves scanning a radiographic film, while the semidirect and direct methods use digital receptors such as photostimulable phosphor plates (PSP) and solid-state sensors (CCD), respectively. (1, 2) The use of positioning devices and protective barriers is common to prevent cross-contamination. Digital radiography offers several advantages, including significant reduction in radiation exposure, rapid image acquisition, ease of manipulation and analysis, reduced environmental impact, lower retake rates due to technical errors, and unlimited storage without loss of quality. (3, 4) Image enlargement on monitors also facilitates communication with the patient and clinical decision-making. Therefore, this study aimed to evaluate radiographic images of artificial teeth under different exposure times, kilovoltages (kV), and milliamperages (mA), using direct and indirect digital sensors in the context of endodontics.(3, 4)
