The use of optical magnifying devices in periradicular microsurgery.

Microsurgery is a more precise modification of present procedures with less operative trauma and improved healing. The basic risk with traditional periradicular surgery arises from potential damage to major vessels or nerve bundles. These potential problems can be fixed using optical magnifying tools such as dental operating microscopes and endoscopes. Instruments have been also designed to take the full advantage of increased visibility. The higher magnification and illumination is favorable in all phases of periradicular surgery. The article focuses mainly on the advantages of optical magnifying devices by root-end resection (Tab. 1, Ref. 22).
