Introduction: This study aimed at evaluating the required digital camera resolution used for radiograph digitalization.
Material and Methods: Periapical radiographs were selected from the undergraduate dental clinics at Ingá University (UNINGÁ) and digitalized with three different amateur digital cameras which were set at different megapixel resolutions.
Results: Sony W110 digital camera showed similar acceptability results in all evaluated resolutions, which were VGA, 3, 5 and 7 megapixels (96.6%, 94.7%, 97. 3% and 97.3% respectively). Fuji Finepix 2800HD digital camera presented a 100% of acceptability when set at 7 megapixels resolution. Sony T110 digital camera showed acceptable results when set at 5 megapixels resolution or higher.
Conclusions: The best results were obtained with Fuji Finepix 2800HD digital camera when set at a 7 megapixels resolution. The three brands evaluated, when set at a 5 megapixels resolution or higher, showed adequate results for diagnosis.
