Maxillary first molar with seven root canals diagnosed with cone‑beam computed tomography scanning.

Nonsurgical endodontic therapy of a right maxillary first molar with three roots and seven root canals. This unusual morphology was diagnosed using a dental operating microscope (DOM) and confirmed with the help of cone‑beam computed tomography (CBCT) images. CBCT axial images showed that both the palatal and distobuccal root have a Vertucci type II canal pattern, whereas the mesiobuccal root showed a Sert and Bayirli type XVIII canal configuration. The use of a DOM and CBCT imaging in endodontically challenging cases can facilitate a better understanding of the complex root canal anatomy, which ultimately enables the clinician to explore the root canal system and clean, shape, and obturate it more efficiently.

Non- Surgical Endodontic Management of The Combined Endo- Perio Lesion: Report of Three Case.

Endodontic–periodontal lesions offer a constant challenge to the clinician for diagnosis, treatment and prognosis of the teeth that are of great concern. Treatment and prognosis of endodontic–periodontal diseases vary depending on the cause and the correct diagnosis of each specific condition. This article presents successful healing of combined endo-perio lesions after non-surgical endodontic management with long term follow up.
