Case 340 YO South East Asian healthy male self-referred to our office for #18 and19. RCT for #18 and 19 had been completed not long before, however, both teeth remained symptomatic; there was percussion and biting pain for both #18 and 19. Probings were normal and slight palpation discomfort. Both accesses were sealed with amalgam. Pre-op radiograph showed under-prepared and obturated #19 and under-prepared and overextended #18. Apical RLs noted for both #18 and 19. Non-surgical retreatment was recommended for both.   Upon access, I noted Thermofil was used for obturation material. There were all removed, all canals were cleaned, shaped, and then obturated. #18 displayed C shaped anatomy.
