英文摘要:
      Objective To analyze the re-treatment strategy of post-core restored teeth with failed root canal treatments,and to explore the clinical feasibility of root canal retreatment with or without removing the post-core systems. Methods A total of 22 teeth with root canal treatments and post-core crown restorations were diagnosed with periapical periodontitis.On account of treatment strategy analysis,18 teeth were re-treated by removing the crowns and post-cores.3 teeth were re-treated by removing the crowns and penetrating the post-cores while 1 tooth by penetrating both crown and post-core.Elective restoration and observation of efficacy were then carried out. Results After 12 months of observation,all 22 teeth were successfully re-treated.The treatment process of removing or penetrating the prosthesis didn't affect the secondary restoration of the teeth. Conclusion The treatment of teeth with periapical periodontitis after post-core crown restorations requires comprehensive analysis of various factors to develop a treatment project.Removing and penetrating the post-cores for root canal retreatment are both clinically feasible treatment methods.
