Figure 1: (a) Gingival tissues at the first dental visit. (b) Preoperative radiograph reveals a broken endodontic file and perforation of the furcal space with extrusion gutta-percha. (c) The metallic crown is removed by sectioning it into two halves. (d) Access cavity prepared. (e) The perforation is sealed with mineral trioxide aggregate. (f) Gutta-percha removed from the furcal perforation. (g) Biomechanical cleaning and shaping of the canals followed by obturation and core build. (h) Three months after postobturation showing periapical healing. (i) Persistent probing depth in the furcation area
