The introduction of the surgical operating microscope (SOM) to endodontitcs has dramatically changed the practice of the specialty. In endodontics, the introduction of the SOM is a relatively new concept that is revolutionizing the way procedures are performed.
The degree of magnification depends upon the combination of lenses that are utilized. Most microscopes come with three to five steps of magnification ranging from 3x to 27x. The light source is usually a 100 to 150 watt halogen bulb that is connected to the microscope via a high efficiency fiber optic cable.
Many other options may be added to the microscope such as an assistant’s viewing eyepiece, video, and 35mm cameras. These options provide a very powerful tool that can be used for teaching, patient education, and the variety of other medical purposes.
