Congratulations on your discovery of the BEST dental anatomy application… in 3D! How can we make this claim? Well, simply put, this application was specifically made for dental students (and hygiene students!) BY a recent dental graduate. No more flipping through notes and images and still being left confused. As a future dental professional, it is understood that you are going to be quizzed again and again on identifying teeth quickly and efficiently and knowing the key structures/characteristics of each tooth… been there, done that.

Well here comes “i-DENTify” where you’ll learn to properly and quickly i…dentify all the key structures of each tooth, quickly identify right vs left of the same tooth, and additionally have critical information that allows for the quickest identification of your teeth...which is most essential for your timed identification exams! Did we forget to mention there is also a custom quiz maker with an optional timer? Well there’s that and more, check us out! By joining up with i-DENTify: Dental Anatomy, you will have exactly what you NEED to know based on what the most common identifiable features of each tooth are, all while presented in a 3D format during both the learn and quiz modes.
