The aim of this study was to carry out a retrospective analysis of maxillofacial tumors in children and to present the long-term follow-up results. Our study was performed with a retrospective analysis of 90 patients under the age of 15 years with maxillofacial tumor treated in our clinic between 1985-2002. In addition, treatment modalities and long-term follow-up results of these patients were...

Keratocystic odontogenic tumors (KCOTs) are cystic tumors that arise sporadically or associated with nevoid basal cell carcinoma syndrome (NBCCS). NBCCS is a rare autosomal dominantly inherited disease mainly characterized by multiple basal cell carcinomas, KCOTs of the jaws and a variety of other tumors. PTCH1 mutation can be found both in sporadic or NBCCS associated KCOTs. The aim of the cur...

Calcifying epithelial odontogenic tumors are rare odontogenic neoplasms that account for approximately one percent of all odontogenic tumors. Extra osseous variant is very rare with very few cases being reported in literature Peripheral Calcifying epithelial odontogenic tumor (CEOT) commonly resemble oral hyperplastic or reactive lesions and are histologically similar to their intraosseous coun...

UNLABELLED Odontogenic tumors are neoplasms that develops exclusively in the gnathic bones; they originate from odontogenic tissues, by epithelial or mesenchymal proliferation, or both. AIM To evaluate the incidence of odontogenic tumors in a specific institution, and to compare these findings with other studies in the literature. STUDY FORMAT: A cross-sectional cohort retrospective study. ...

BACKGROUND Tumours arising from odontogenic tissues are rare and constitute a heterogenous group of interesting lesions. The aim of this study was to determine the relative frequency of odontogenic tumors (OT) among Nigerian children and adolescents 19 years or younger. PATIENTS AND METHODS The histopathology records were retrospectively reviewed for all the tumors and tumor-like lesions of t...

OBJECTIVE In jawbones, ameloblastomas and odontogenic keratocysts share many clinical features in common such as aggressiveness, high recurrence rates and radical management options. Understanding the pathogenesis and biological aspects of these tumors would improve the success of diagnose and treatment procedures. The aim of this study was to exhibit the reasons of high recurrence rates and gr...

AIMS AND BACKGROUND The aim of the study was to examine the immunohistochemical expression of a cell-cycle-related factor (p16) in order to elucidate its role in the growth and diffusion of odontogenic tumors. STUDY DESIGN Thirty-six odontogenic tumors were divided into two groups according to their clinical behavior: group A and group B composed of tumors at low and high risk of recurrences,...

background: vascular endothelial growth factor (vegf) is capable of initiating angiogenesis in blood vessels and may act as mitogenic agent for epithelium of odontogenic cysts and tumors. this study was conducted to evaluate the role of epithelial vegf expression in odontogenic cysts and ameloblastoma and its correlation with argyrophilic nucleolar organizer region counts to assess its role in ...

OBJECTIVES Since its recognition as a physiologic process associated with tumor, among molecular mechanisms involved in tumor progression, defects in regulation of apoptosis have generated an accelerating volume of research that has sought to elucidate the role of programed cell death in pathogenesis and treatment of various tumors. Therefore, this study was performed to understand better the d...

Calcifying epithelial odontogenic tumor is a rare odontogenic neoplasm. Its occurrence in the maxillary sinus is very rare. Maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures.  We report a case of calcifying epithelial odontogenic tumor involving maxillary sinus in a 48 years old female patient with the oral mucosal involvement. The purpose o...
