Treatment of bucco-accessory root canal of a maxillary incisor with a combination of cone beam computed tomography and continuous supersonic wave condensation

Objective: A novel treatment for bucco-accessory root canal (bARC), which is difficult to treat by regular endodontic therapy, is discussed. Clinical Presentation and Intervention: A bARC in the maxillary right incisor with symptomatic irreversible pulpitis was detected using cone beam computed tomography (CBCT) after conventional dental radiography. The pulp was extirpated and the canal enlarged using rotary files and chemo-mechanical reagents. The main root canal and bARC were obturated with thermoplastic gutta-percha using continuous wave condensation. Postoperative CBCT revealed a completely treated bARC. Conclusion: A combination of CBCT and continuous wave condensation is ideal for bARCs in incisors.
