Department of Oral and Maxillofacial Pathology, Faculty of Health Sciences, University of Pretoria, Pretoria, South Africa.
Purpose: This study aimed to investigate the role of DNA ploidy and proliferation index in distinguishing ameloblastoma (AB) from ameloblastic carcinoma (AC).
Methods: The study included 29 ACs, 6 conventional ABs that transformed into ACs, and a control cohort of 20 conventional ABs. The demographics and clinicopathologic details of the included cases were summarised and compared.

Background: Calretinin is a 29 kilodalton (KDa) calcium-binding protein that is expressed in normal and tumoral tissues. The expression of calretinin has been shown in the dental epithelium during odontogenesis and in different odontogenic cysts and tumors such as ameloblastoma. Since the epithelium of calcifying odontogenic cyst (COC) is similar to ameloblastoma and in both lesions, an arrangement of loose cells similar to stellate reticulum is seen, we aimed to investigate the comparative expression of calretinin in COC and ameloblastoma.

Odontogenic keratocyst (OKC) and ameloblastoma (AM) are common jaw lesions with high bone-destructive potential and recurrence rates. Recent advancements in technology led to significant progress in understanding these conditions. Single-cell and spatial omics have improved insights into the tumor microenvironment and cellular heterogeneity in OKC and AM.

Department of Oral and Maxillofacial Radiology and Dental Research Institute, School of Dentistry, Seoul National University, Seoul, Republic of Korea.
Background: Ameloblastoma is the most prevalent odontogenic tumor of the jaw, with a significant recurrence rate. It was conventionally classified radiographically as unilocular or multilocular. As 3D images become more common, there is a need to reassess this classification.

Ameloblastoma is a benign odontogenic epithelial tumor characterized by its aggressive behavior and a high likelihood of local recurrence if not fully excised. Ameloblastomas are a common type of slow-growing, true jaw tumor which may present as solid, multicystic or unicystic forms and originate from odontogenic epithelium and exhibit a variety of histological patterns. Keratoameloblastoma is considered to be a rare variant of ameloblastoma associated with more intense keratinization.
