Patient presents with a symptomatic lateral lesion on tooth #8. Root canal therapy was completed 2-years prior. Symptoms: Palpation sensitivity mid-root. Periodontal probing was within normal limits. Differential Dx: Fracture or lateral canal.
Since probing was WNL, surgical endodontic tx is an option.
During surgery, a large lateral canal was visible in the surgical window. The lateral canal was ultrasonically prepped and sealed with MTA cement. 6-month recall shows bone regeneration.
