The possibility that the presence of lactoferrin in aspirates of odontogenic cyst fluid might be a useful preoperative diagnostic marker for odontogenic keratocyst was investigated. Using qualitative and quantitative immunodiffusion methods fluid from 29 of 29 dental (radicular) cysts, 12 of 14 dentigerous cysts and 27 of 31 keratocysts were found to contain lactoferrin. Although some of the hi...

BACKGROUND & OBJECTIVE Matrix metalloproteinases (MMPs) are involved in local invasion of ameloblastomas. This study was to evaluate the role of matrix metalloproteinase inducer (EMMPRIN) in angiogenesis in ameloblastomas by analyzing EMMPRIN expression and microvessel density (MVD) in ameloblastomas and odontogenic cysts. METHODS EMMPRIN expression and MVD in 41 specimens of ameloblastoma an...

P63 may have a role in tumorigenesis and cytodifferentiation of odontogenic lesions. We investigated the immunohistochemical expression of P63 in a total of 30 cases of odontogenic cysts and tumors. The percentage of positive cells was calculated in the lining of odontogenic cysts and islands of ameloblastoma. P63 expression was evident in all types of odontogenic lesions. P63 was expressed thr...

Background/Aim. Surgical treatment of odontogenic cysts in childhood could be accompanied by injury of important anatomical structures. Even though enucleation is considered to be preferable treatment of odontogenic cysts, the specificities of pediatric age favor more conservative surgical approach. The aim of this study was to assess the effectiveness of decompression as the uttermost treatmen...

Objectives: To focus on distribution of different histologic types of odontogenic cysts (OCs), patient gender and age, and cyst location in an Iranian population and compare results with others studies in different geographic locations and/or racial populations. Materials and Methods: A 40-year retrospective study of 1189 patients with OCs that were diagnosed from 1971 to 2011 in the Department...

OBJECTIVES Orofacial cysts are broadly divided into odontogenic and nonodontogenic types, epithelial or non-epithelial, and developmental or inflammatory in origin. The odontogenic cyst is an osseous-destructive lesion that most commonly affects the jaw. It is formed by activation of odontogenic cell rests entrapped within the bone or gingival tissue of the jaws, such as the epithelial remains ...

Sections of tissue embedded in paraffin wax from 18 selected odontogenic cysts were studied both histologically and immunohistochemically with antibodies to cytokeratins using the indirect peroxidase technique. The cysts were divided on a clinical and histological basis into two equal groups comprising dentigerous cysts and odontogenic keratocysts. It was possible to differentiate the two cyst ...

The Glandular Odontogenic Cyst (GOC) is a rare developmental odontogenic cyst that occurs 75% of the time in the mandible and rarely presents in persons under 20 years of age [1]. The GOC was originally described by Padayachee and Van Wyk [2] in 1987 who reported on two cases of multilocular mandibular cysts with features of both Botryoid Odontogenic Cyst (BOC)and central mucoepidermoid tumor (...

BACKGROUND Odontogenic cysts (OC) are the most frequent lesions of the jaws and their constant epidemiological update is necessary and indispensable. Therefore the principal objective of this report was To determine prevalence and clinical-demographical characteristics of OC in a Mexican sample. MATERIAL AND METHODS 753 cases of OC coming from the archive of a head and neck histopathological ...
