transforming growth factor atpha (tgf-a), parathyroid hormone-tike proteins (pthlp) and oncogene p53 proteins have all been demonstrated in a variety of human tumors anil have been implicated as causes of tumor cell aggressiveness. the present study determined the existence of these peptides and their immunohistochemicat profiles in ameloblastomas. odontogenic keratocysts and dentigerous cysts ...

Peripheral odontogenic lesions are considered to be rare within the classification of odontogenic tumors. They share the same microscopic characteristics of their central counterparts. Here, we report an ulcerated mass of the maxillary gingiva that on histopathological examination was diagnosed as peripheral developing odontoma or peripheral ameloblastic fibroodontoma. The diagnosis of this tum...

Peripheral odontogenic tumors (POTs) are uncommon, and even rarer in the pediatric population. A peripheral odontogenic fibroma (PODF) is the most numerous POT in the general and pediatric populations. The purpose of this paper was to report an unusual case of PODF in a very young child who was born at 29 weeks’ gestation. The literature on PODFs in the pediatric population is reviewed.

Objectives: Odontogenic tumors occupy an important position among head and neck tumors. Although, rarely encountered in medical practice but they considered increasingly challenging lesions for the clinicians due to their overlapping clinical histopathological features. This study was designed determine relative frequency of central odontogenic Iraqi population by utilizing 2022 WHO tumor class...

Odontogenic tumor is one of the tumors of great significance in the oral region. The process of its development remains obscure. It seems very advantageous in the investigation of dontogenic tumor to establish experimental models in laboratory animals. However, experimental attempts of induction of odontogenic tumor have not been very successful. In recent years, the carcinogenic property of ni...

In 1991, Handlers and colleagues described the Central odontogenic fibroma (COF) as a distinct entity which is a rare benign odontogenic tumour and up to the present, only 78 cases of it have been published. COF usually occurs in an adult patient and has a predilection for the anterior region of the jaws. A 2.8:1 female to mail ratio is typically noted. This article presents a case of COF in a ...

Cementoblastomas are rare benign odontogenic tumors. Diagnosis of these lesions must be made by an association of clinical, radiographic, and histopathological findings. Cementoblastomas rarely occur in both primary and permanent dentitions. We describe the sixth case of cementoblastoma in the literature with the involvement of both deciduous and permanent teeth. The aim of this case report is ...

Odontogenic tumors constitute a group of heterogeneous lesions of benign and malignant neoplasms with variable aggressiveness. Ameloblastomas are a group of benign but locally invasive neoplasms that occur in the jaws and are derived from epithelial elements of the tooth-forming apparatus. We previously described orosomucoid-1 protein expression in odontogenic myxomas. However, whether orosomuc...
