Serota Figs 4A-4D

4A. An 8mm infrabony defect is evident along the distal proximal aspect of the root of tooth #1.5. 4B. Debris present in the [DMR] of the tooth #1.4 demonstrates a fracture line, however, there is no indication of cuspal separation. Removal of the amalgam revealed extension of the fracture into the cuspal stress plane of the buccal and axial line angle. 4C. The root canal space was obturated using a warm vertical condensation technique. Lateral branches of the root canal system are noted. The tooth was restored with a bonded composite restoration using the Bioclear Matrix System developed by Dr. David Clark, DDS [Tacoma, WA]. 4D. A post-operative peri-apical radiograph taken in 2020 shows osseous regeneration and reformation of the PDL in the infra-bony defect along the distal aspect of the root.
