THE USE OF MAGNIFICATION IN ENDODONTIC THERAPY …
Telescopes or loupes have been readily available ina variety of configurations and magnifications. Withthe aid of a fiberoptic headlamp system, light can beprojected in the line of sight to prevent the creation ofshadows in the surgical field and render optimal visual-ization of the treatment site. However, the magnificationof loupes is limited ( to ) and their optics areconvergent, which creates eye strain and fatigue. In orderto address the limitations present in these devices, clini-cians adopted new techniques and were the first medical specialists to uti-lize the operating microscope in a clinical 1921, Nylen performed a surgical procedure withthe operating Jannetta performed aprocedure called microvascular decompression to treattrigeminal neuralgia, the event became the subject ofcontroversy (to use or not to use the microscope) in theneurosurgical surgical operating micro-scope (SOM) has been recently introduced in dentistry,specifically in endodontics , where increased magnifica-tion and illumination have resulted in improved technicalaccuracy and Surgical Operating MicroscopeThe surgical operating microscope consists of threeprimary components the supporting structure, the bodyof the microscope, and the light Supporting StructureIt is essential that the microscope be stable while in opera-tion, yet remain maneuverable with ease and exceptionalprecision, particularly when used at high power.
The objective lens is the final optical element, and its focal length determines the working distance between the microscope and the surgical field.
