Serota Figs 3A – 3D

3A. The intraoral periapical radiograph reveals a PRRL at the root terminus of tooth #1.1. A large area of internal resorption is evident mid-root of tooth #2.1. The resorption has perforated the lateral aspect of the root causing disruption of the interproximal bone. 3B. A post-operative radiograph shows the endodontic treatment of #1.1. Tooth #2.1 has been sealed with white MTA to the incisal level of the resorptive defect as it demonstrates minimal root discolouration. Were the tooth be treated today, the choice of obturation material would be Endosequence BC putty [Brassler USA, Savannah, GA]. 3C. The PRRL associated with tooth #1.1 has resolved. The resorptive defect has been reduced in size, radiolucent deposits are evident within the resorptive crypt. 3D. The sagittal slice of the CBCT volume shows an intact cortical plate. The presence of calcified deposits is evident in the residual resorptive defect which has been significantly reduced
