background: pericoronal tissue is the soft tissue located between the bony crypt and the impacted tooth, which is histologically composed of fi brous connective tissue and is usually lined by the reduced enamel epithelium. increased epithelial cell proliferation in the pericoronal tissue is associated with pathological changes such as development of an odontogenic cyst or an epithelial odontoge...

BACKGROUND CD166 is a glycoprotein of an immunoglobulin super family of adhesion molecules that has been associated with aggressive characteristics and high recurrence rate of tumors. Different odontogenic lesions exhibit considerable histological variation and different clinical behavior. In an attempt to clarify the mechanisms underlying this different behavior, the present study investigates...

Dentigerous cysts are the most common developmental odontogenic cyst of the jaws. They are more frequent in males and although most often affected teeth are maxillary canines and mandibular third molars, they may also be related with supernumerary or an ectopically erupted tooth. Our aim was to report the management of ectopic third molar tooth related with a dentigerous cyst in maxillary sinus...

AIM To determine the immunocytochemical pattern of expression of transforming growth factor (TGF) alpha, epidermal growth factor (EGF), and TGF beta in the three most common types of odontogenic jaw cyst. METHODS Growth factor expression was detected in paraffin wax sections of odontogenic cysts (27 odontogenic keratocysts, 10 dentigerous cysts, and 10 radicular cysts) using a streptavidin-bi...

PURPOSE AND INTRODUCTION Dentigerous cysts are epithelial in origin and are the most commonly found cyst in children. The majority of these lesions are usually a radiological finding and are capable of quite large before being diagnosed. The standard treatment for these cysts is the enucleation and the extraction of the affected tooth. However, if the patient is a child and the affected tooth i...

Aim: To present a report the case of a 10-year-old boy with a dentigerous cyst associated with inverted and fused supernumerary teeth in the anterior maxilla and to point out the relationship between supernumerary teeth and dentigerous cysts. Method: The supernumerary teeth were removed and the cyst was enucleated. Result: The patient has remained asymptomatic and experienced no recurrence duri...

Aims: The aim of the current study was to detect and compare Human papillomavirus (HPV) in dentigerous cyst and ameloblastoma. Materials and methods: The study included 32 samples, which distributed into dentigerous cysts (n=16) and ameloblastomas (n=16). Conventional PCR assay using SPF1/2 consensus primers and immunohistochemical analysis were performed for the detection of HPV‒DNA and HPV‒L1...
