Diagnosis

Patient’s general dentist initiated endodontic treatment; but, was unable to locate any canals. Clinical testing confirmed the presence of a non-vital pulp and symptomatic apical periodontitis. The CBCT axial view displays three separate roots present in the apical third.

Treatment

Three canals were located and instrumented followed by the Sonendo GentleWave^® procedure to augment cleaning and disinfection. The postoperative radiograph confirms the filling of three canals plus a lateral canal exiting on the distal aspect of the mesiobuccal root.
