MINIMALLY INVASIVE APPROACH TO SEVERELY CALCIFIED ROOT CANALS USING A SURGICAL MICROSCOPE: A CASE REPORT

抄録

Severely calcified root canals cause pulp canal obliteration and it is difficult to treat the root canal precisely. Here, a successful and safe treatment for severe calcification is introduced. The root canal orifice was searched based on cone-beam computed tomography images. An access opening was then created using a diamond-coated ultrasonic tip, and excessive removal of root dentin was avoided using a surgical microscope. Root canal preparation was safely performed using nickel-titanium rotary files. Clinical skills to manipulate these tools are necessary for the treatment of these types of cases.
