The 50 years old patient was referred to our office by his general dental practitioner for endodontic treatment. He complained about dull pain and biting tenderness associated with tooth 46.

The access cavity was driven by the caries process and after the removal of the infected dentine, the pulp chamber was unroofed and the pulp stones were removed to locate the canal orifices.

The MG3 Blue file system from Perfect was chosen for managing this case.
