A CASE REPORT OF MICROSCOPIC TREATMENT FOR INTERNAL ROOT RESORPTION WITH PERFORATION

Abstract

There are often cases in which the use of a microscope in treatment allows preservation of a tooth that would ordinarily have been deemed untreatable and extracted. Tools such as cone-beam computed tomography (CBCT), mineral trioxide aggregate (MTA), ultrasonic instruments, nickel-titanium rotary files, and composite resins used in combination with the microscope are also of great benefit in this regard. A case of internal resorption accompanied by perforation at the root furcation of the mandibular left first molar is presented. Conservative treatment was performed under a microscope, using MTA to repair the perforation and then using a bulk-fill type composite resin, obtaining satisfactory results.
