Root Canal Retreatment and Intracoronal Bleaching on the Maxillary First Premolar

Abstract:

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
