Giant Complex Odontoma of the Posterior Mandible: A Case Report.
Cureus
September 2024
Department of Oral Pathology, Kothiwal Dental College and Research Centre, Moradabad, IND.
Complex odontoma is a benign odontogenic tumor composed of disorganized dental tissues, including enamel, dentin, cementum, and pulp. Unlike compound odontomas, which exhibit tooth-like structures, complex odontomas form a mass without anatomical organization. These tumors frequently present without symptoms and are typically identified inadvertently during standard dental imaging procedures.

Dental Specialist Center, Hafar Albaten, Saudi Arabia.
Article Synopsis
- Primordial odontogenic tumor (POT) is a rare benign tumor commonly found in children and young adults, often presenting as asymptomatic swelling, particularly in the posterior mandible.
- A systematic review of 26 studies, covering 36 POT cases, analyzed various clinical characteristics, treatments, and outcomes, revealing a median patient age of 12 years and a slight male predominance.
- Most POTs exhibited unilocular radiolucencies on imaging and were primarily treated through enucleation and curettage, with one recurrence noted among cases with follow-up data.
Immunohistochemical Expression of Calretinin in Dentigerous Cyst Transforming Into Unicystic Ameloblastoma: A Case Report.
Cureus
September 2024
Department of Oral Pathology, Manav Rachna Dental College, Faridabad, IND.
The term "unicystic ameloblastoma" describes cystic lesions that exhibit radiographic, clinical, or gross characteristics of a jaw cyst. However, histologic examination reveals a typical ameloblastomatous epithelium lining the cyst cavity, with or without luminal and/or mural tumor proliferation. Unicystic ameloblastoma is a less prevalent kind of ameloblastoma.

October 2024
Department of Oral and Maxillofacial Pathology, Faculty of Health Sciences, University of Pretoria, Pretoria Oral Health Care Centre, Office 6-11, Corner of Steve Biko and Dr Savage Roads, Pretoria, 0084, South Africa.
Purpose: The current study aimed to investigate the use of surrogate immunohistochemical (IHC) markers of proliferation and stem cells to distinguish ameloblastoma (AB) from ameloblastic carcinoma (AC).
Methods: The study assessed a total of 29 ACs, 6 ABs that transformed into ACs, and a control cohort of 20 ABs. The demographics and clinicopathologic details of the included cases of AC were recorded.
Mandibular Odontogenic Tumors That Caused Delayed Eruption of the First Molar: A Case Report of Two Patients.
Cureus
August 2024
Department of Oral and Maxillofacial Surgery Ⅱ, Nihon University School of Dentistry, Tokyo, JPN.
Article Synopsis
- Delayed eruption of permanent teeth is common, but impaction of the mandibular first molar is rare, often caused by issues like odontogenic cysts and tumors.
- The article details two cases where odontogenic tumors led to the delayed eruption of the mandibular first molar in children, with specific diagnoses of ameloblastic fibro-odontoma and odontoma.
- Treatment involved curettage of the tumors and fenestration of the impacted molars, which resulted in the successful eruption of the first molar in both cases.
