Dentistry has become more sophisticated and complex thus requiring precised motor skills and visual acuity. Optical magnification has expanded the horizons of dentistry. Microscope was initially started in ophthalmology, it's benefits in endodontic therapy which was best performed remains unparalleled. Traditional endodontics has been based on feel not sight. Since the endodontic surgical field is measured in millimeters, endodontic therapy has always been very dependent from the tactile sensation of the operator and its anatomic knowledge. The use of magnification in dentistry appears to be of increasing interest. With the recent advances of magnification devices with increased magnification and illumination there is improved technical accuracy and performance. Now the use of such magnification systems is a very popular practice in dentistry as well. By providing both intense focused light as well as a high degree of magnification, the endoscope, orascope, dental loupes and operating microscope has become an important part of the armamentarium for many endodontics.
