Khang T. Le, DDS

A 40-year-old male presented with severe intermittent pain on the lower left side of the mouth for two months. His diagnosis was pulpal necrosis and symptomatic apical periodontitis. The old filling material and underlying carious lesion were removed and missing tooth structure was restored. The tooth was prepared with conservative straight-line access, and the canals were instrumented to size 20/.07. The GentleWave^® Procedure was employed to clean and disinfect the root canal system, followed by obturation with warm vertical technique. Post-procedure, an isthmus was visualized between the two mesial canals, and a lateral canal and an apical delta were seen on the distal canal. Evaluation at 6, 9 and 18 months showed the tooth was asymptomatic. Significant bone regrowth with complete periradicular healing were evident at 18-month recall.
