UNLABELLED Dentigerous cysts are one of the most common odontogenic cysts of the oral cavity. Odontogenic cysts can give rise to a variety of neoplasms. Carcinoma arising in a dentigerous cyst is extremely rare, with a review of literature showing near 30 cases. The present report describes 2 cases of primary intraosseous squamous cell carcinoma originated from a dentigerous cyst. The first one...

AUTHORS: Dr. Shalini Singhal Senior lecturer Dr. Hirak Bhattacharya Reader Dr. Manvi Agarwal Senior Lecturer Department of Periodontics Institute of Dental Sciences, Bareilly ABSTRACT LATERAL PERIODONTAL CYST is a rare odontogenic cyst of developmental origin. It occurs on the lateral periodontal region of a vital tooth and has specific histologic features. In this paper a case of a lateral per...

BACKGROUND Odontogenic necrotizing fasciitis of the neck is a fulminant infection of odontogenic origin that quickly spreads along the fascial planes and results in necrosis of the affected tissues. It is usually polymicrobial, occurs frequently in immunocompromised patients, and has a high mortality rate. CASE PRESENTATION A 69-year old Mexican male had a pain in the maxillar right-canine re...

Background. The aim of this study was to investigate myofibroblast (MF) density in a broad spectrum of odontogenic cysts and tumors and the relation between the density of MFs and the clinical behavior of these lesions. Methods. A total of 105 cases of odontogenic lesions, including unicystic ameloblastoma (UAM), solid ameloblastoma (SA), odontogenic keratocyst (OKC), dentigerous cyst (DC), rad...

Introduction: Complication of an odontogenic infection to an orbital abscess is not a common presentation. The progression from a simple toothache to a condition that may lead to loss of vision is sudden and severe.   Case Report: We report a rare case in which a patient developed facial cellulitis that progressed to orbital abscess after unsterile dental manipulation by a medical fraudster (“q...

Midkine (MK; a low molecular weight heparin-binding growth factor) is a multifunctional cytokine. MK plays a role in morphogenesis of many organs including teeth through epithelial-mesenchymal interactions. We immunohistochemically examined MK expression in various human odontogenic tumors. There was no difference in positive rate and intensity of MK between benign odontogenic tumors and their ...

BACKGROUND The aims of this study were to investigate the immunolocalization of ezrin and its relationship with the podoplanin expression in keratocystic odontogenic tumors. MATERIAL AND METHODS The immunohistochemical expressions of ezrin and podoplanin by odontogenic epithelium were evaluated in keratocystic odontogenic tumors using monoclonal antibodies. RESULTS Our results showed strong...

OBJECTIVE To retrospectively evaluate the treated cases with odontogenic abscess and identify the outcome of odontogenic infections, their characteristics and treatment modalities. MATERIALS AND METHODS This retrospective study was performed by collecting data from 310 patient records at the oral and maxillofacial surgery department of Taleghani hospital, Tehran, Iran from January 2001 to Jan...

The Odontogenic Keratocyst (OKC), first described by Phillipsen in 1956, has been reclassified as odontogenic neoplasm and has been renamed as Keratocystic Odontogenic Tumor (KCOT) as reported in WHO classification of head and neck tumors in 2005. Odontogenic keratocysts are benign intraosseous tumors of odontogenic origin that occur most commonly in the jaw. In particular, they have a predilec...

Hymenoptera order includes bees, which have a stinging apparatus at the tail capable of delivering venom to the affected tissues. Myocardial infarction, acute renal failure, Necrotizing fasciitis, fatal infection and hemifacial asymmetry, are some of the unusual reactions reported following hymenoptera stings. This paper reports a case of bee sting in the right floor of the nose that mimicked a...
