This app is mainly designed for dental students wanting to learn more about endodontics (diagnosis and treatment). It will help them determine pulpal and periradicular diagnosis. It will also help indicate whether a root canal is recommended and show the steps for performing root canals from instrumentation to obturation.
 
Please note that there are multiple methods of doing root canals. This method was taught to me at my school.
Disclaimer: Do NOT attempt to perform any root canal procedures unless you are properly trained and licensed.
