The use of high-power magnification has greatly increased our abilities as dental professionals to identify and diagnose the dental problems that require our treatment. Advances in magnification and illumination have been the biggest contributor to better, more thorough, and precise dental treatment. It is just a simple fact that you cannot treat what you do not see.
This is a distinct advantage when doing root canal treatment
on teeth. There are many canals and small intricacies that before magnification were never discovered or cleaned out to the best of our ability. Seeing better directly translates to higher-quality dentistry.
