With the introduction of microscope usage into dentistry during the last decade or more, not only do microscopes improve magnification of the operative field but they have provided improved ergonomics at chairside. It is wise in many situations to include a microscope for the assistant. This will enable the assistant to know exactly what is happening and recognize any change in the procedure.
Microscopes actually deliver on the promise of comfortable sit-down‑dentistry. Using the microscope the dentist no longer needs to twist and bend the body to obtain good visibility. The microscope provides its own light source and is directly positioned over the oral cavity like a dental light. Essentially the dentist sits motionless and is able to sit at the 12 o’clock position even while working with mandibular molars by learning to bring the patient to him or her, instead of attempting to bring him or herself to the patient. The assistant using a microscope along the side of the dentist can also maintain good chair positioning while being able to anticipate the next needed instrument. The dentist can adjust the patient’s head with minimal movement to improve patient positioning in order to improve the dentist’s operating posture.
