Endodontic retreatment and comprehensive endo-prosthetic of premolars: A case report

Background: The failure of endodontic treatment caused by failure of the restoration and bacterial invation. Alongside proper chemical and mechanical preparation and hermetic obturation of the root canal system, another essential factor is ensuring a permanent and hermetically-sealed restoration following endodontic treatment. Endodontic retreatment encompasses the efforts to salvage a failing previously endodontically treated tooth. As a result of advances in endodontic materials and adhesive systems, restorations in the form of fiber post and adhesively cemented crown are becoming a choice in cases of teeth that have extensive damage. Case: A case is presented a 45-year-old female was referred to Prof. Soedomo Dental Hospital with a complaint of pain in mandibular second premolar which was earlier endodontically treated. Clinical and radiographic examinations showed damaged restorations, gutta percha filling that are not hermetic and radiolucent on periapical. A successful endodontic retreatment premolar using rotary retreatment file and preparation with crown down technique using rotary progressive multiple tapering file, with comprehensive endo-prosthetic treatment using prefabricated fiber post and porcelain fused to metal crown. Conclusion: Clinical and radiographic evaluation after 6 months showed complete healing and good adaptation of the restoration. The outcomes of this case showed that failure of endodontic retreatment respond favorably to endodontic retreatment, with proper indication, prefabricated fiber post and porcelain fused to metal crown can provide an effective conservative and esthetic option for reinforcing endodontically treated teeth. © 2020 Trans Tech Publications Ltd, Switzerland.
