Teeth #11 and #21 (F\u00e9d\u00e9ration Dentaire Internationale) exhibited discolouration and incisal-third crown fractures. Preoperative radiographs revealed poorly compacted radiopaque material in the root canals of both teeth, with #21 presenting a wide-open apex and periapical lesion. The radiographic presentation of #11 was perplexing, showing a mature root apex superimposed over a blunderbuss apex. Cone-beam computed tomography confirmed a labial root perforation in #11. A pulpal diagnosis of previously initiated therapy was established for both teeth. #21 was diagnosed with asymptomatic apical periodontitis, while #11 had symptomatic apical periodontitis with labial root perforation. Treatment included non-surgical root canal therapy followed by surgical perforation repair. At the 4-year follow-up, both teeth were functional and asymptomatic, with complete periapical healing.<\/jats:p>","DOI":"10.1136\/bcr-2024-263852","type":"journal-article","created":{"date-parts":[[2025,6,24]],"date-time":"2025-06-24T14:25:20Z","timestamp":1750775120000},"page":"e263852","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Managing iatrogenic root perforation masked by deceptive radiographic presentation in maxillary central incisor"],"prefix":"10.1136","volume":"18","author":[{"given":"Daiasharailang","family":"Lyngdoh","sequence":"first","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Dr Z.A Dental College, Aligarh Muslim University, Aligarh, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4917-3880","authenticated-orcid":false,"given":"Sharique","family":"Alam","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Dr Z.A Dental College, Aligarh Muslim University, Aligarh, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nandani","family":"Kumari","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Dr Z.A Dental College, Aligarh Muslim University, Aligarh, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Surendra Kumar","family":"Mishra","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Dr Z.A Dental College, Aligarh Muslim University, Aligarh, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,6,24]]},"reference":[{"key":"2025082710250444000_18.6.e263852.1","unstructured":"Eleazer PD , Glickman GN , McClanahan SB , et al .
