The radiographic appearance on panoramic imaging and cone-beam computed tomography (CBCT) frequently does not correlate with the true biological nature of these lesions. On CBCT, classic odontogenic tumors often demonstrate mixed radiolucent\u2013radiopaque patterns with ill-defined borders, internal calcifications, septations, or other structural features. The diagnostic challenge arises when an odontogenic tumor mimics a unilateral, well-defined radiolucent area or a cystic lesion with clear borders and no associated tooth displacement, erosion, root resorption, or cortical bone dehiscence. Panoramic radiography has inherent diagnostic limitations but remains widely used for routine dental screening. CBCT provides enhanced three-dimensional assessment and improves diagnostic accuracy in the evaluation of jaw lesions. A marked increase in dental follicle diameter necessitates differentiation between cystic transformation, inflammatory processes, and other odontogenic pathologies. Cortical swelling and bone asymmetry warrant careful evaluation. In this context, an atypical cyst-like lesion detected on routine panoramic radiography prompted a needle aspiration biopsy, which revealed a dry tap and suggested a solid lesion. This prompted CBCT evaluation. Two juvenile cases are presented in which clinical findings, panoramic radiography, and CBCT provided discordant diagnostic impressions of cystic-appearing lesions with well-defined borders and bone expansion. These cases illustrate a diagnostic pathway in which imaging demonstrates a cyst-like appearance with benign radiological features, fine-needle aspiration biopsy reveals the absence of cystic fluid, and histopathology confirms that radiology alone cannot reliably distinguish true cysts from solid odontogenic tumors in pediatric patients.<\/jats:p>","DOI":"10.3390\/diagnostics16030439","type":"journal-article","created":{"date-parts":[[2026,2,2]],"date-time":"2026-02-02T14:12:46Z","timestamp":1770041566000},"page":"439","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["\u201cDry Tap\u201d Fine-Needle Aspiration Biopsy as a Diagnostic Clue in Cyst-like Juvenile Jaw Lesions Mimicking Dentigerous Cysts on Panoramic Radiography and Cone-Beam Computed Tomography"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4215-0798","authenticated-orcid":false,"given":"Kamil","family":"Nelke","sequence":"first","affiliation":[{"name":"Maxillo-Facial Surgery Ward, EMC Hospital, Pilczycka 144, 54-144 Wroc\u0142aw, Poland"},{"name":"Academy of Applied Sciences, Health Department, Academy of Silesius in Wa\u0142brzych, Zamkowa 4, 58-300 Wa\u0142brzych, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Klaudiusz","family":"\u0141uczak","sequence":"additional","affiliation":[{"name":"Maxillo-Facial Surgery Ward, EMC Hospital, Pilczycka 144, 54-144 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0628-2419","authenticated-orcid":false,"given":"\u00d6mer","family":"Uranbey","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Ayd\u0131n Adnan Menderes University, 09010 Ayd\u0131n, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B\u00fc\u015fra","family":"Ekinci","sequence":"additional","affiliation":[{"name":"Department of Medical Pathology, Faculty of Medicine, Ayd\u0131n Adnan Menderes University, 09010 Ayd\u0131n, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Angela Rosa","family":"Caso","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillo-Facial Surgery, University of Siena, Viale Aldo Moro, 2, 53100 Siena, SI, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8180-948X","authenticated-orcid":false,"given":"Micha\u0142","family":"Gontarz","sequence":"additional","affiliation":[{"name":"Department of Cranio-Maxillo-Facial Surgery, Maxillo-Facial Surgery Clinic, University Hospital in Cracow, Macieja Jakubowskiego 2 Street, Nowy Prokocim, 30-688 Krak\u00f3w, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4357-2271","authenticated-orcid":false,"given":"Maciej","family":"Janeczek","sequence":"additional","affiliation":[{"name":"Department of Biostructure and Animal Physiology, Wroc\u0142aw University of Environmental and Life Sciences, Ko\u017cuchowska 1, 51-631 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zygmunt","family":"Stopa","sequence":"additional","affiliation":[{"name":"Department of Cranio-Maxillofacial Surgery, Oral Surgery and Implantology, Medical University of Warsaw, Lindleya 4, 02-005 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0682-4743","authenticated-orcid":false,"given":"Piotr","family":"Kuropka","sequence":"additional","affiliation":[{"name":"Division of Histology and Embryology, Department of Biostructure and Animal Physiology, Wroc\u0142aw University of Environmental and Life Sciences, Cypriana K.
