Odontogenic keratocyst has been renamed as by world health organization in 2005. It is a benign intraooseous neoplasm of the jaw. They develop from the dental lamina remenants in the mandible and maxilla.Odontogenic keratocyst is of particular interest because of its recurrence rate and aggressive behavior. We present a case in a middle aged lady patient.

The calcifying epithelial odontogenic tumor (CEOT), also known as the Pindborg tumor, is a benign and rare odontogenic tumor accounting for 0.4-3 percent of all odontogenic tumors. Few reports of the incidence of this tumor exist in Iran. The most frequent location is the mandibular premolar and molar area; less frequently the lesion is found in the maxilla. In clinical features, a painless slo...

The term odontogenic keratocyst was first used by Philipsen in the year 1956. The lesion was renamed by him as keratocystic odontogenic tumor (KCOT) and reclassified as odontogenic neoplasm in the World Health Organization's 2005 edition that occurs commonly in the jaws having a predilection for the angle and ascending ramus of mandible. In contrast, KCOTs arising in the maxillary premolar regi...

BACKGROUND AND AIMS The aim of this study was to investigate the relative frequency of developmental odontogenic cysts in an Iranian population. MATERIALS AND METHODS In this study 245 cysts from both jaws, treated in the Faculty of Dentistry at Tabriz University of Medical Sciences during a 10-year period from 1998 to 2008, were analyzed in order to evaluate the incidence of such cysts. We h...

The function of the jaw for feeding and speech has long been the discussion of both speechlanguage pathologists and occupational therapists. This article will examine the relationship between jaw movements or jaw skill levels for feeding quality and speech clarity. What has been missing in our discussions concerning jaw function is the role the jaw plays in the development of speech sounds. Inf...

Osteosarcoma (OS) is a malignant neoplasm characterised by the formation of osteoid matrix by neoplastic cells. It is the most common primary malignant bone tumor accounting for 20% of all sarcomas, although its occurrence in the jaw is rare. It shows typical clinical behaviour but varied radiological and histopathological features. It presents various histological aspects. We report a case of ...

Experiments were performed on human elbow flexor and extensor muscles and jaw-opening and -closing muscles to observe the effect on rhythmic movements of sudden loading. The load was provided by an electromagnetic device, which simulated the appearance of a smoothly increasing spring-like load. The responses to this loading were compared in jaw and elbow movements and between expected and unexp...

Tremulous jaw movements are rapid vertical deflections of the lower jaw that resemble chewing but are not directed at any particular stimulus. In rats, tremulous jaw movements can be induced by a number of conditions that parallel those seen in human parkinsonism, including dopamine depletion, dopamine antagonism, and cholinomimetic drugs. Moreover, tremulous jaw movements in rats can be attenu...
