A 73\u2010year\u2010old female patient presented with a fractured tooth #21 with a carious crown. Pulp sensibility testing using cold spray elicited a sharp and prolonged painful response, consistent with a diagnosis of symptomatic irreversible pulpitis with normal apical tissues. Conventional periapical radiography suggested an unusual root morphology, which was further evaluated using cone\u2010beam computed tomography (CBCT). CBCT imaging revealed a bifurcated root configuration with two distinct root canals and separate apical foramina. Root canal treatment was performed under dental operating microscope magnification using a crown\u2010down preparation technique, followed by obturation with cold lateral compaction. Clinical and radiographic evaluation at the 1\u2010year follow\u2010up demonstrated a successful outcome. This case underscores the importance of careful diagnostic assessment and the judicious use of advanced imaging modalities for the detection and management of rare anatomical variations, even in teeth that typically exhibit simple root canal anatomy.<\/jats:p>","DOI":"10.1002\/ccr3.71779","type":"journal-article","created":{"date-parts":[[2025,12,31]],"date-time":"2025-12-31T01:58:15Z","timestamp":1767146295000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Twin\u2010Rooted Anomaly: Endodontic Management of a Rare Case of a Maxillary Central Incisor With Two Roots"],"prefix":"10.1002","volume":"14","author":[{"given":"Mohsen","family":"Aminsobhani","sequence":"first","affiliation":[{"name":"Department of Endodontics Dental Research Center, AJA  Tehran Iran"},{"name":"Tehran University of Medical Sciences  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-0806-0125","authenticated-orcid":false,"given":"Maryam","family":"Babaahmadi","sequence":"additional","affiliation":[{"name":"Department of Endodontics, School of Dentistry Tehran University of Medical Sciences  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,30]]},"reference":[{"issue":"3","key":"e_1_2_14_2_1","first-page":"174","article-title":"Endodontic Management of a Maxillary Central Incisor With Two Roots: A Case Report and Literature Review","volume":"18","author":"Namaei Ghasemi S.","year":"2023","journal-title":"Iran Endod Journal"},{"key":"e_1_2_14_3_1","doi-asserted-by":"publisher","DOI":"10.5005\/jp-journals-10005-2616"},{"issue":"2","key":"e_1_2_14_4_1","first-page":"104","article-title":"Endodontic Management of Maxillary Central Incisor With Two Roots, and Lateral Incisor With a C\u2010Shaped Canal","volume":"18","author":"Mahadevan M.","year":"2023","journal-title":"A Case Report Iran Endod Journal"},{"key":"e_1_2_14_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(84)90085-9"},{"key":"e_1_2_14_6_1","doi-asserted-by":"publisher","DOI":"10.1590\/0103-6440201302448"},{"key":"e_1_2_14_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/iej.12724"},{"key":"e_1_2_14_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2014.04.016"},{"key":"e_1_2_14_9_1","doi-asserted-by":"publisher","DOI":"10.5005\/jp-journals-10005-1456"},{"key":"e_1_2_14_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/ger.12266"},{"key":"e_1_2_14_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2017.01.032"},{"key":"e_1_2_14_12_1","doi-asserted-by":"publisher","DOI":"10.2334\/josnusd.49.245"},{"key":"e_1_2_14_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2009.05.028"},{"key":"e_1_2_14_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2015.08.001"},{"key":"e_1_2_14_15_1","doi-asserted-by":"publisher","DOI":"10.4103\/2278-9626.105388"},{"key":"e_1_2_14_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0099-2399(06)80074-9"},{"key":"e_1_2_14_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2015.08.017"},{"issue":"3","key":"e_1_2_14_18_1","first-page":"235","article-title":"Endodontic Retreatment of a Maxillary Central Incisor With Two Root Canals in a Patient With Cleft Lip and Palate","volume":"14","author":"Miranda Candeiro G.
