Mandibular molar with dilacerated root and canal exiting short of apex.

Diagnosis Patient presented with a non-vital pulp and symptomatic apical periodontitis. The preoperative radiograph displays an atypical root and canal configuration. The CBCT sagittal view shows that the mesiolingal and distal canals join and the mesiobuccal canal exits the root short of the root apex.   Treatment After access opening, three canals were located and […]

Maxillary bicuspid with three canals.

Diagnosis Patient presented with symptomatic irreversible pulpitis and symptomatic apical periodontitis. The preoperative radiograph displays internal anatomy with a single canal that divides into three canals in the coronal third of the root.   Treatment After access opening, three canals were located and instrumented. The postoperative radiograph confirms the filling of three canals with multiple […]

Mandibular molar with severely dilacerated root.

Diagnosis Patient presented with a non-vital pulp and chronic apical periodontitis. The pre-operative radiograph showed a radiolucent area surrounding the apical third of the root and advanced horizontal bone loss on the distal. The mesial root displayed a double curvature and there was a sharp dilaceration of the distal root with the canal exiting on […]

Maxillary lateral incisor with a second root.

Diagnosis Patient presented with a non-vital pulp and chronic suppurative apical periodontitis. The preoperative radiographs showed aberrant anatomy that suggestive of a dens evaginatus. A gutta percha cone in the sinus tract traced to the distal aspect of the root and possible second canal. The CBCT axial view confirmed the presence of an additional root […]

Mandibular molar with separated instrument.

Diagnosis Patient presented with previously initiated endodontic treatment. The preoperative radiograph disclosed that there was a separated instrument in the apical third of the mesial root. No other clinical signs or symptoms were present.   Treatment Three canals were located and it was confirmed that a separated instrument was present in the mesiolingual canal. It was […]

Mandibular molar with dilacerated root and additional portal of exit.

Diagnosis Patient presented with a non-vital pulp and chronic suppurative apical periodontitis. The pre-operative radiograph showed a radiolucent area surrounding the apical third of the root.   Treatment Three canals were located and instrumented. The distal root was not negotiable to the radiographic apex with hand or rotary files; so, the Sonendo GentleWave® procedure was […]

Mandibular molar with canal anastomosis.

Diagnosis Patient presented with a non-vital pulp and symptomatic apical periodontitis. The preoperative radiograph displayed a widened periodontal ligament space associated with the mesial root apex. Treatment Four canals were located and instrumented followed by the Sonendo GentleWave® procedure to augment cleaning and disinfection. The postoperative radiograph confirms the filling of the four canals plus […]

Mandibular molar with canal anastomosis and multiple portals of exit.

Diagnosis Patient presented with a non-vital pulp and symptomatic apical periodontitis. The preoperative radiograph did not display any atypical findings.   Treatment Three canals were located and instrumented followed by the Sonendo GentleWave® procedure to augment cleaning and disinfection. The post- operative radiograph displays an anastomosis between the mesial canals in the apical third of […]

Mandibular bicuspid with aberrant anatomy.

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 […]

Mandibular molar with “C” shaped canal.

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 […]
