Figure 3 Post-treatment situation of the mandibular second molar and follow-ups. A: Occlusive situation of the left molars; B and C: Three-month (B) and one-year (C) radiographic follow-up images demonstrating healing of the periapical lesion; D-H: Cone beam computed tomography (CBCT) images at 1-year radiographic follow-up; I: Three-dimensional reconstruction of CBCT images presenting healing of the lingual cortical plate. White and yellow arrows represent the mesial root canals and a distal root canal, respectively; orange arrows show the regions of periapical healing.
