From: A novel simplified approach for endodontic retrograde surgery in short single-rooted teeth
A representative case received the modified approach. (A) The CBCT scan revealed a lesion at the periapical region of the right central incisor and lateral incisor, and another independent lesion at the left central incisor and lateral incisor. (B) A periapical radiograph taken during root canal treatment indicated that the immature maxillary central incisors received orthograde obturated with iRoot-BP for 6 mm and filled with gutta-percha for the crown part, while two lateral incisors received obturation with gutta-percha and iRoot-SP by the warm gutta-percha obturation technique. (C) A periapical radiograph was taken at the 3-month follow-up. (D) A photograph taken before the surgery. The blue line represented the operative incision. (E), (F) and (G) The lateral incisors received retro-preparation and retro-filling with iRoot BP after apicoectomy. (H) A postoperative periapical radiograph was taken immediately. (I) Follow-up imaging showed partially healed of lesions 3 months after surgery. (J) A CBCT scan at the 12-month follow-up revealed healthy apical bone tissue around all roots
