Diagnosis

Patient presented with a non-vital pulp and asymptomatic apical periodontitis. The CBCT axial view confirms the presence of a “C” shaped root anatomy with three separate canals connected by ribbons of pulpal tissue.

Treatment

Three main canals were located and instrumented. This was followed by the Sonendo GentleWave^® procedure to augment cleaning and disinfection of this difficult anatomy. The postoperative radiograph confirms the filling of several canal system fins and irregular extensions.
