Their clinical appearance may resemble that of other palatal illnesses, complicating diagnosis and treatment. Prevention of problems requires early detection and endodontic treatment. A 26-year-old female patient presented with a 2 cm diameter palatal abscess, significant pulsatile discomfort, fever, and enlargement of the anterior hard palate. Clinical examination showed grade 1 mobility of the central and lateral incisors, percussion discomfort, and negative pulp vitality in the case of the lateral incisor. Cone-beam computed tomography (CBCT) showed two radiolucent lesions: a posterior cystic lesion near the first molar and an anterior lesion near the upper left lateral incisor. Palatal cortical bone puncture and soft tissue extension indicated the abscess origin. According to the clinical and imaging evaluation, the upper left lateral incisor had a persistent periapical lesion of endodontic origin that a palatal abscess with cortical bone perforation had exacerbated.<\/jats:p>","DOI":"10.3390\/diagnostics15172195","type":"journal-article","created":{"date-parts":[[2025,8,29]],"date-time":"2025-08-29T16:18:15Z","timestamp":1756484295000},"page":"2195","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Palatal Abscess of Endodontic Origin with Extensive Radiolucency in Maxillary CBCT Imaging"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2585-2632","authenticated-orcid":false,"given":"Diana","family":"Marian","sequence":"first","affiliation":[{"name":"Department of Dentistry, Faculty of Dentistry, \u201cVasile Goldi\u0219\u201d Western University of Arad, 94-96 Revolutiei Blvd., 310025 Arad, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2580-2432","authenticated-orcid":false,"given":"George Dumitru","family":"Constantin","sequence":"additional","affiliation":[{"name":"Discipline of Clinical Practical Skills, Department I Nursing, Faculty of Medicine, Victor Babes University of Medicine and Pharmacy, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ademir Horia","family":"Stana","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine, \u201cVasile Goldi\u0219\u201d Western University of Arad, 94-96 Revolutiei Blvd., 310025 Arad, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-6347-3497","authenticated-orcid":false,"given":"Ioana Elena","family":"Lile","sequence":"additional","affiliation":[{"name":"Department of Dentistry, Faculty of Dentistry, \u201cVasile Goldi\u0219\u201d Western University of Arad, 94-96 Revolutiei Blvd., 310025 Arad, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7500-7181","authenticated-orcid":false,"given":"Tareq","family":"Hajaj","sequence":"additional","affiliation":[{"name":"Department of Propaedeutics and Dental Materials, Faculty of Dentistry, Victor Babes University of Medicine and Pharmacy, 2 Eftimie Murgu Sq., 300041 Timisoara, Romania"},{"name":"Research Center in Dental Medicine Using Conventional and Alternative Technologies, Faculty of Dental Medicine, Victor Babes University of Medicine and Pharmacy of Timisoara, 9 Revolutiei 1989 Ave., 300070 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-6217-6022","authenticated-orcid":false,"given":"Otilia Lavinia","family":"Gag (Stana)","sequence":"additional","affiliation":[{"name":"Department of Dentistry, Faculty of Dentistry, \u201cVasile Goldi\u0219\u201d Western University of Arad, 94-96 Revolutiei Blvd., 310025 Arad, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e15","DOI":"10.1016\/j.tripleo.2011.01.008","article-title":"Apical infection spreading to adjacent teeth: A case report","volume":"111","author":"Komabayashi","year":"2011","journal-title":"Oral Surg.
