AIM AND BACKGROUND An odontogenic keratocyst (OKC) or keratocystic odontogenic tumor (KCOT) and giant cell granuloma (GCG) in the jaws are common lesions which have been studied extensively in detail over the years. However, a lesion showing features of both is exceptionally rare and is reported only twice in the literature till date. CASE DESCRIPTION A rare case of OKC in mandible showing fo...

Inflammatory jaw cysts comprise a group of lesions that arise as a result of epithelial proliferation within an inflammatory focus due to a number of causes. Radicular cysts are the most common inflammatory cysts. These cysts are found most commonly at the apices of the involved teeth. These cysts are seldom very large and very rarely cross the midline. There has been a review for Odontogenic k...

BACKGROUND The aim of this study was to determine the range of all histologically diagnosed odontogenic cysts along with age range, sex distribution and site of presentation over a 30-year period. METHODS All entries for odontogenic cysts occurring during 1975-2004 inclusive were retrieved and analysed for demographic data. RESULTS A total of 55,446 specimens were received, of these 7121 (1...

The histologic pattern of OKC is distinct and hence the cyst has potential for more aggressive behaviour than other cysts of the jaws. When inflammation is present within the cyst wall of an OKC, the character of the cyst lining changes from the classical pattern to a non-keratinized stratified squamous lining typical of other inflammatory cysts. This transformation often occurred quite abruptl...

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...

Odontogenic keratocyst (OKC) is a cyst of tooth origin with an aggressive clinical behavior including a high recurrence rate. OKC demographics in the northwestern United States are presented and compared to those reported elsewhere. A total of 430 cases were obtained from 393 patients of the northwest region over a period of 15 years. Data evaluated included: site, gender, age, race, and associ...

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.
