This study describes the surgical management of two Root Canal Perforations (RCP) in maxillary incisors aided by CBCT scans. In the first case, a patient was referred for retreatment due to a history of overfilling. The chief complaint was frequent discomfort and slight oedema in upper front tooth (#9). Periapical radiography showed gutta-percha extruded out of the root canal. CBCT revealed a RCP and more than 1 cm of a gutta-percha cone extruded out of the apex. At follow-up one year after surgical procedure for the removal of the extruded filling material and apicoectomy, bone tissue formation was observed, without clinical symptoms. In the second case, a series of RCP was verified in multiple maxillary incisors of the same patient, who was referred due to a history of unresolved pain. On clinical examination, no abnormalities of the soft tissue were observed. Imaging exams revealed RCP in all maxillary incisors. The patient underwent conventional treatment and follow-up surgical procedures to seal the RCP. One year after surgery, imaging exams demonstrated tissue formation without clinical symptoms. RCP is considered a serious error in operative procedure. Once properly diagnosed, localised and sealed with biomaterial, a favourable prognosis is often achieved. MTA offered a good seal of perforations, with promising results. The use of CBCT in diagnosis allowed better security, correct positioning and improved surgical planning of RCP.
