Use of Cone-beam Computed Tomography as a Critical Component in the Diagnosis of an Infected Nasopalatine Duct Cyst Mimicking Chronic Apical Abscess: A Case Report.

J Endod 2021 Apr 24. Epub 2021 Apr 24.

Department of Endodontics, Israel Defense Forces Medical Corps, Tel Hashomer, Israel.

Nasopalatine duct cysts (NPDCs) and other nonodontogenic lesions of the oral cavity may mimic odontogenic pathoses. We present a case of a 22-year-old man with a history of dental trauma and a lesion displaying the typical clinical and radiographic signs of a chronic apical abscess- a buccal sinus tract that was traced to a radiolucent area in the periapex of a maxillary central incisor. A comprehensive diagnostic process that included a cone-beam computed tomographic scan and a histopathologic examination of the lesion after complete enucleation led to the final diagnosis of an infected NPDC.

Összefoglaló. Bevezetés: Az állcsonti cysták helytálló diagnosztikája a klinikai, radiológiai és patológiai leletek együttes értékelésével lehetséges. Korábbi munkánk során többször tapasztaltuk a klinikoradiopatológiai kommunikáció és korreláció hiányát, és ez olykor inadekvát diagnózisok felállításához vezetett. Read More

"Radiographic demonstration of association of ubernaculum Dentis (Gubernaculum tract) in odontogenic cysts and tumors"-A CBCT finding.

Indian J Radiol Imaging 2020 Jul-Sep;30(3):340-343. Epub 2020 Oct 15.

Department of Oral Pathology and Microbiology, Subharti Dental College, Swami Vivekanand Subharti University, Meerut, Uttar Pradesh, India.

Spectrum of lesions that occur in the jaws have a cyst-like radiographic appearance. These lesions may be odontogenic or non-odontogenic and are often difficult to differentiate them on the basis of their clinical, radiographic features alone. Among odontogenic lesions without mineralization, ameloblastomas, odontogenic keratocysts, and dentigerous cysts can all appear as well-defined, unilocular, well-corticated, lucent lesions that can mimic with non-odontogenic cysts and tumors like nasopalatine duct cyst, aneurysmal bone cyst, central giant cell granuloma, hemangioma and so on.

The mechanism: how dental resorptions occur in ameloblastoma.

Dental Press J Orthod 2019 Sep 5;24(4):21-32. Epub 2019 Sep 5.

Universidade de São Paulo, Faculdade de Odontologia de Ribeirão Preto, Programa de Pós-Graduação em Odontopediatria (Ribeirão Preto/SP, Brazil).

Knife-edge or blunt root resorptions characterize ameloblastomas and are pathognomonic for this tumor, because they differentiate ameloblastomas from simple bone cysts, odontogenic keratocysts and nasopalatine duct cysts, which do not lead to resorption of involved teeth. Despite the very high frequency and importance of these characteristics for a differential diagnosis, a microscopic examination should also be conducted before defining the diagnosis and the treatment plan for these cases. This paper describes a six-step hypothesis to explain the mechanism by which ameloblastomas promote the characteristic root resorptions found in association with these benign epithelial tumors, which have a fibrous capsule formed by islands and epithelial cords that mimic the dental lamina, invade neighboring tissues and release mediators (IL-1, EGF) of tooth and root resorption.

Nasopalatine duct cyst mimicking an endodontic periapical lesion: a case report.

Gen Dent 2016 Jan-Feb;64(1):63-6

Lesions of nonendodontic origin, such as nasopalatine or globulomaxillary cysts, may mimic periapical radiolucencies associated with pulpal pathosis, and incorrect diagnosis may lead to unnecessary endodontic treatment. Horizontal root fractures most commonly affect the maxillary central and lateral incisors. Prognosis depends largely on the level of fracture; fractures in the apical third have the best prognosis, and those in the cervical third have the worst. Read More

Department of Oral and Maxillofacial Surgery, Harborview Medical Center, School of Dentistry, University of Washington, 4West Clinic, 325 9th Avenue, Seattle, WA 98104, USA. Electronic address:

Nonodontogenic cysts within the jaws are not a common presentation in the pediatric population. Cysts within the pediatric population tend to be developmental and odontogenic in nature. Although nonodontogenic cysts of the jaws are relatively uncommon, it is imperative the clinician understand their clinical behavior and management because failure to do so can result in increased patient morbidity.

Nasopalatine duct cyst, a delayed complication to successful dental implant placement: diagnosis and surgical management.

J Oral Implantol 2014 Apr;40(2):189-95

British Society of Oral Implantology Southport, Merseyside, UK.

The dental literature reports frequently on both the success and survival of dental implants, whereby the focus remains on the biological response of hard and soft tissue to the implants. The predication and anticipation of adverse implant events can then lead to the preemption of implant loss. However, biological situations can arise that are outside the control of the clinician.

A clinical report demonstrating the significance of distinguishing a nasopalatine duct cyst from a radicular cyst.

BMJ Case Rep 2014 Mar 18;2014. Epub 2014 Mar 18.

Department of Oral Pathology and Microbiology, Manipal College of Dental Sciences, Manipal, Karnataka, India.

Endodontic diagnosis is challenging and depends on the organisation of information from the patient history, clinical examination and analysis of the pulp, radiographic and histopathological assessment. A 35-year-old man was endodontically treated for radiolucency in relation to the roots of maxillary central incisors as it was a provisionally diagnosed case of radicular cyst. Since the palatal swelling persisted, the lesion was re-evaluated using relevant diagnostic aids and a diagnosis of nasopalatine duct cyst (NPDC) was made, which was missed during the initial assessment.
