Above is a dollar image taken with a camera and no magnification. Imagine that you are looking into a tooth trying to find canals the size of Washington's pupil.
Above is the dollar image taken with the lowest magnification on the microscope. Remember to look at Washington's eye
The above magnification is where I do most of my work and then go to higher magnification in specific instances.
Here is the highest magnification. As you can see it is much easier to find a canal the size of Washington's pupil at a higher magnification.
The microscope has changed endodontics and allows us to find canals that we couldn't have found before. I can't imagine working without one!
