Medical student This application is not to be taken seriously and definitely not to be utilized as a study aid. It possesses many flaws. First, in the quiz section in consideration of the answers required by the application the information in the case histories is absent for example a patient presenting with benign prostatic hyperplasia. Which is not mentioned in the question, yet in the answer provided you are expected to be aware of this which is impossible. There are spelling mistakes which any medical literature or study aid should lack. When you input an answer it does not inform you of the correct answer if one makes an error. In order to correctly examine radiographs it is necessary to be able to zoom in, some of them are so tiny yet you are expected to be able to examine them. I have uninstalled this application quickly.
The application displays the periapical radiographic technique without the use of the positioner.
