Peripheral calcifying odontogenic cyst in maxillary anterior gingiva: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background Calcifying odontogenic cysts (Gorlin cysts) most commonly present centrally and have only rarely been reported in peripheral locations. The purpose of this report is to describe a new case of peripheral calcifying odontogenic cyst (PCOC) occurring in the anterior maxillary gingiva and to review the management and differential ...

Ameloblastic fibroma

Journal of Indian Academy of Oral Medicine and Radiology, 2016
Ameloblastic fibroma, is a mixed odontogenic tumor, which commonly affects young children under the age of 20 years, with the mandibular premolar-molar region being the most common site of manifestation. This is a case report of a 25-year-old female with a swelling in the right posterior mandibular region since 4 months, which was subsequently ...

Ameloblastic Carcinoma [PDF]

Journal of Maxillofacial and Oral Surgery, 2010
Ameloblastic carcinoma (AC) is a rare aggressive malignant epithelial odontogenic tumor of the maxillofacial skeleton with a distinct predilection in the mandible. It may appear de novo or originate from a pre-existing ameloblastoma or odontogenic cyst. It exhibits cytological features of ameloblastoma and carcinoma.

Smad1/5 signal transduction regulates the ameloblastic differentiation of induced pluripotent stem cells [PDF]

Brazilian Oral Research, 2020
Induced pluripotent stem (iPS) cells could be induced into ameloblast-like cells by ameloblasts serum-free conditioned medium (ASF-CM), and bone morphogenetic proteins (BMPs) might be essential during the regulation of this process.

Molecular mechanism for transcriptional regulation of the parathyroid hormone gene by Epiprofin

The FEBS Journal, EarlyView.
The secretion of parathyroid hormone (PTH) from the chief cells in the parathyroid glands is regulated by the concentration of extracellular calcium. Epiprofin (Epfn) expression is induced by NFATc2 in response to elevated serum calcium, and Epfn negatively regulates PTH production.

Ameloblastic carcinoma

Journal of Indian Academy of Oral Medicine and Radiology, 2009
Ameloblastoma of jaws are common and locally destructive tumors originating from odontogenic apparatus. They constitute approximately 1% of all jaw tumors with 80% occurring in the mandible. Ameloblastoma exhibiting a frank malignancy is a rare entity and occurs in less than 1% of all ameloblastomas. Among the two jaws, ameloblastic carcinoma involving

Single cell RNA sequencing reveals human tooth type identity and guides in vitro hiPSC derived odontoblast differentiation (iOB)

Frontiers in Dental Medicine, 2023
Over 90% of the U.S. adult population suffers from tooth structure loss due to caries. Most of the mineralized tooth structure is composed of dentin, a material produced and mineralized by ectomesenchyme derived cells known as odontoblasts.

Ameloblasts in Health and Disease

Dentistry and Medical Research, 2021
Abstract Ameloblasts are highly sensitive enamel-forming cells. They are derived from ectoderm and undergo a series of transformative changes in their life cycle. The functional efficiency of ameloblasts depends on various factors such as intracellular and extracellular environment, epithelial–mesenchymal interactions, and ...
