Abstract:
Most mandibular first molars have 2 mesial canals. Two cases of failed endodontically treated first mandibular molars are presented with 2 obturated mesial canals. The cases were retreated with a third mesial canal identified, and instrumented and obturated with resolution of the patients' signs and symptoms. These cases show that consideration must be made to recognize the possibility of a third mesial canal and perform complete treatment to minimize the possibility of failure.
