Proliferating cell nuclear antigen (PCNA) is a nuclear protein synthesized in the late G1 and S phase of the cell cycle, and immunohistochemical detection of the protein represents a useful marker for the proliferating fraction of cells in tissue specimens. PCNA expression was studied in odontogenic keratocysts (n = 15) and ameloblastomas (n = 46) using an avidin-biotin-peroxidase complex metho...

objective: the ortho keratinized odontogenic cyst (ooc) is a rare lesion originates from dental lamina and clinically, it may be mistaken for many other odontogenic cysts and tumors. microscopically, it should be distinguished from kcot because of differences in biologic behavior and histologic features.   case: an interesting case of ooc arising in the edentulous mandibular right first premola...

An odontogenic keratocyst (OKC) and a giant cell granuloma (GCG) in the jaws are two well known entities, which have been reviewed extensively. However, the synchronous occurrence of these two lesions is exceptionally rare. We report a case of OKC exhibiting foci of CGC-like lesion.

Duchenne muscular dystrophy, a debilitating disease affecting male cIdldren, presents special considerations for the dentist faced with an oral-surgical problem. When general anesthesia is contraindicated, local anesthesia and a change in technique is indicated. One technique of outpatient surgical management of an odontogenic keratocyst, in a patient with Duchenne muscular dystrophy, is descri...

Odontogenic keratocyst (OKC) is a common developmental odontogenic cyst affecting the maxillofacial region. Multiple OKCs are usually seen in association with nevoid basal cell carcinoma syndrome (NBCCS) but approximately 5% of patients with OKC have multiple cysts without concomitant syndromic presentation. This report represents a case of multiple OKCs in a non-syndromic patient.

Purpose: Odontogenic cysts and tumors comprise a major component of lesions the oral maxillofacial region. The pathogenesis these involves interaction between odontogenic epithelium ectomesenchyme. However, clinical behavior biological entities is unpredictable. aim this study was to evaluate role Cyclooxygenase 2 (COX-2) in prognostication lesions.Material method: : In formalin-fixed paraffin-...
