They usually occur after trauma or alterations in local hemodynamics. Secondary ABCs can occur due to vascular changes and inflammation caused by existing periapical infection. A 25-year-old male patient reported with the chief complaint of recurrent swelling and pus discharge in his upper front tooth region for 3 months. He gave a history of trauma 16 years ago. He had undergone root canal treatment in his upper front tooth 4 years ago. Preoperative radiograph and cone-beam computed tomography showed the presence of a large periapical radiolucency and an unusual radio-opaque foreign body. Endodontic therapy was initiated, and a 5 mm mineral trioxide aggregate plug was given. Thorough periapical curettage was done. Histopathological analysis gave a diagnosis of ABC, and scanning electron microscopy analysis identified the foreign body as zinc oxide cement. Follow-up examination showed distinct radiographic healing with a decrease in the size of the lesion. Accurate diagnosis, achieved through a combination of radiographs and histopathology, is crucial for ensuring complete lesion removal and reducing the risk of recurrence.<\/jats:p>","DOI":"10.4103\/ccd.ccd_436_25","type":"journal-article","created":{"date-parts":[[2026,3,27]],"date-time":"2026-03-27T05:00:25Z","timestamp":1774587625000},"page":"53-57","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Weed out the Unwanted: Endosurgical Management of a Foreign Body with Cystic Lesion"],"prefix":"10.4103","volume":"17","author":[{"given":"Ashish K.","family":"Jain","sequence":"first","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Bharati Vidyapeeth (Deemed to be University), Dental College and Hospital, Navi Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anandita","family":"Sinha","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Bharati Vidyapeeth (Deemed to be University), Dental College and Hospital, Navi Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vaishnavi Ratnakar","family":"Patankar","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Bharati Vidyapeeth (Deemed to be University), Dental College and Hospital, Navi Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kirti B.","family":"Buva","sequence":"additional","affiliation":[{"name":"Department of Oral Pathology and Microbiology, Bharati Vidyapeeth (Deemed to be University), Dental College and Hospital, Navi Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bhavani Nagendra","family":"Sangala","sequence":"additional","affiliation":[{"name":"Department of Oral Pathology and Microbiology, Bharati Vidyapeeth (Deemed to be University), Dental College and Hospital, Navi Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rahul","family":"Rao","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Bharati Vidyapeeth (Deemed to be University), Dental College and Hospital, Navi Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,3,26]]},"reference":[{"key":"R1-20260420","doi-asserted-by":"crossref","first-page":"920","DOI":"10.1111\/j.1365-2591.2008.01423.x","article-title":"Foreign body in the apical portion of a root canal in a tooth with an immature apex: A case report","volume":"41","author":"Prabhakar","year":"2008","journal-title":"Int Endod J"},{"key":"R2-20260420","doi-asserted-by":"crossref","first-page":"249","DOI":"10.1111\/j.1365-2591.2006.01099.x","article-title":"On the causes of persistent apical periodontitis: A review","volume":"39","author":"Nair","year":"2006","journal-title":"Int Endod J"},{"key":"R3-20260420","doi-asserted-by":"crossref","first-page":"593","DOI":"10.1097\/00004770-200109000-00010","article-title":"Foreign body in the periradicular area","volume":"27","author":"Srivastava","year":"2001","journal-title":"J Endod"},{"key":"R4-20260420","doi-asserted-by":"crossref","first-page":"1206","DOI":"10.1038\/Modpathol.3880224","article-title":"Cytogenetic-morphologic correlations in aneurysmal bone cyst, giant cell tumor of bone and combined lesions.
