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.

The dental practice is demanding and time consuming. A dentist's musculoskeletal health can be affected adversely if appropriate working position is neglected. Area that is often overlooked is the physical strain caused due to long hours of working in uncomfortable and incorrect posture which in turn can contribute greatly to musculoskeletal disorders, stress, and loss of productivity. Occupation related diseases are increasing day by day and one amongst them is musculoskeletal disorders due to improper ergonomics in dentistry. These disorders can result in pain and dysfunction of the neck, back, legs and hands and fingers. Dentists develop musculoskeletal problems which are related to suboptimal work environment ergonomics that might be responsible for improper sitting postures and movements. In Greek, "Ergo," means work and, "Nomos," means natural laws or systems. Ergonomics, therefore, is an applied science concerned with designing products and procedures for maximum efficiency and safety. The principles of ergonomics touch all aspects of our life and can be applied in work place, at home and even in recreational and leisure activities.
