Background: Iatrogenic complications such as accidental perforation of the root or the floor of the pulp chamber may occur. Case Report: Patient was referred for root canal retreatment of the mandibular left second molar with periapical lesion evidenced through radiographic examination. During post removal, iatrogenic perforation occurred at the mesial face of the distal root. After clinical localization of the perforation and bleeding control, MTA was applied. In a second appointment, the root canal filling was removed and the chemical-surgical retreatment of the canals was performed, followed by the obturation with gutta-percha and sealer. Patient returned after three days reporting no pain. After 6 months, 3, 7 and 10 years of follow-up. Conclusion: Absence of pain, normal periodontal probing and lack of radiolucent area at the region of perforation and the periapices were detected, which evidenced the successful repair of the tooth.

Summary Background: Extrusion of root canal sealers may cause damage to the surrounding anatomic structures. Clinical symptoms like pain, swelling and paresthesia or anesthesia may be present. The purpose of this presentation is to describe two cases of root canal sealer penetration into periapical tissues. A different treatment management was followed in each case. Case reports: A 55 year-old man underwent root canal retreatment of the right mandibular first molar tooth due to a periapical lesion. Postoperative periapical radiographs revealed the presence of root canal sealer (AH26) beyond the apex in the distal root in proximity to the mandibular canal. The patient reported pain for the next 7 days. Radiographic examination after 1 year showed complete healing of the periapical area and a small absorption of the root canal sealer. A 42 year-old woman was referred complained of swelling and pain in the area of the right maxillary first incisor. Radiographic examination showed extrusion of root canal sealer in the periapical area associated with a periapical lesion. Surgical intervention was decided upon, which included removal of the sealer, apicoectomy of the tooth and retrograde filling with MTA. After 1 year, complete healing of the area was observed. Conclusion: In conclusion, cases of root canal sealer extrusion, surgical treatment should be decided on only in association with clinical symptoms or with radiographic evidence of increasing periapical lesion.

Introduction. Inadequate root canal preparation and obturation are potential causes of endodontic failure. Failed root canal treatment with intrinsic discoloration requires root canal re-treatment and intracoronal bleaching. Due to the extensive loss of hard tissues on occlusal area, the restoration requires intracanal retention with short fiber-reinforced composite. Case report. A 17-year-old male patient came to the Clinic of Conservative Dentistry Dental Hospital Prof. Soedomo. He reported pain and discomfort on maxillary first premolar while chewing after root canal procedure had been performed few months before. He felt unconvinience with the discoloration happened on those tooth. Patient had endodontic treatment one year ago and the tooth was restored with glass ionomer cement. Objective examination showed glass ionomer restoration was still in good condition, the tooth was sensitive to percussion but not to palpation, and showed no mobility. Periapical radiograph showed incomplete obturation with radioluscent around periapical region. Retreatment followed by intracoronal bleaching was performed under rubber dam isolation. Tooth was restored with short fiber reinforced composite and composite resin. After 3 month, patient was recalled for examine the previous sign and symptomps. Periapical radiograph showed diameter of periapical lesion was smaller and tooth functioned normally. Conclusion. Root canal retreatment and intracoronal bleaching are suitable options for teeth with failed root canal treatment and intrinsic discoloration
