A 2 year recall demonstrates the healing of both the apical and lateral lesions. Excess sealer which was initially extruded through the coronal, lateral canal into the lesion, was resorbed without incident. There was no presence of any fistula. The patient was asymptomatic. Had it chosen an alternate pathway, i.e. along the root surface, it would have travelled coronally and eventually communicated with the base of the pocket, creating the endo-perio complication.
Many endodontic lesions exist asymptomatically, yet still represent signs of infection.
Had this tooth been vital at the time endodontic therapy was initiated, there would not be any evidence of lateral lesions or lateral canals. Nor would there be any apical root resorption.
