p53 and PCNA expression in keratocystic odontogenic tumors compared with selected odontogenic cysts Summary: The aim of this study was to evaluate p53 and PCNA expression in different odontogenic lesions regarding their different clinical behaviors. Slices prepared from 94 paraffin-embedded tissue blocks (25 radicular cysts (RC), 23 dentigerous cysts (DC), 23 keratocystic odontogenic tumors (KC...

Tooth eruption disturbances associated with developmental odontogenic cysts represent a particular challenge in orthodontic treatment. Early diagnosis, crucial for prompt and effective therapy, is possible thorough radiological analysis. Three-dimensional digital images provided by CBCT are indispensable to establish an interdisciplinary orthodontic–surgical treatment plan. The aim of this pape...

A calcifying cystic odontogenic tumor (CCOT) is a proliferation of odontogenic epithelium and scattered nests of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass. It was previously described by Gorlin et al in 1962 as a calcifying odontogenic cyst. Dentigerous cysts are developmental odontogenic jaw cysts, commonly manifesting in the second and third...

statement of problem: the aggressive nature and high recurrence rate of odontogenic keratocysts (okcs) may be due to unknown factors inherent in the epithelium or because of enzymatic activity in the fibrous wall. bcl-2 protein is characterized by its ability to inhibit apoptosis. purpose: the aim of the present study was to analyze the expression of bcl-2 protein in okcs and to compare it with...

conclusions we reported a rare case of large residual cyst. dental practitioners should consider this lesion in the differential diagnosis of radiolucent lesions of the jaw bone. case presentation a 59-year-old iranian man complaining of a dull pain in his left side of the mandible after falling down one month ago was referred to the department of oral and maxillofacial pathology, hamadan unive...

Aim: Various odontogenic cysts may occur in the jawbones during childhood, including radicular cysts, dentigerous and keratocysts. Treatment for such ranges from conservative approaches to radical surgical procedures. The present study evaluates effect of only decompression method treating various children. 
 Materials Methods: A total 16 pediatric patients (four girls, 12 boys; mean age 9...

Dentigerous cysts are the most common developmental cysts of the jaws, most frequently associated with impacted mandibular third molar teeth. Dentigerous cysts around supernumerary teeth, however, account for 5% of all dentigerous cysts, with most developing around a mesiodens in the anterior maxilla. This report describes two cases of a dentigerous cyst associated with an impacted mesiodens. B...

Orthokeratinized odontogenic cyst (OOC) is a developmental cyst that occurs in the jaw. it was initially defined by the world health organization as the orthokeratinized variant of odontogenic keratocyst (OKC). However, studies have shown that OOC has a peculiar clinicopathologic aspects when compared with other developmental odontogenic cysts, especially OKC's. The orthokeratinized odontogenic...

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 ...

Dentigerous cysts are developmental odontogenic cysts associated with the crown of an unerupted tooth most commonly located at permanent Mandibular 3rd Molars and the Maxillary Canines. They rarely involve deciduous teeth and supernumerary teeth [5%]. We report successful management of two rare cases of maxillary labial swelling due to a dentigerous cyst associated with an impacted mesiodens. T...
