AIM To determine the immunocytochemical pattern of expression of transforming growth factor (TGF) alpha, epidermal growth factor (EGF), and TGF beta in the three most common types of odontogenic jaw cyst. METHODS Growth factor expression was detected in paraffin wax sections of odontogenic cysts (27 odontogenic keratocysts, 10 dentigerous cysts, and 10 radicular cysts) using a streptavidin-bi...

OBJECTIVES The purpose of this study was to analyze the prevalence, demographic patterns and management of odontogenic infections in patients undergoing treatment in an outpatient dental emergency service of a university hospital. MATERIALS AND METHODS In a retrospective study of the year 2012, all patients suffering from odontogenic infections were included. Demographic data, diagnosis and t...

OBJECTIVE In jawbones, ameloblastomas and odontogenic keratocysts share many clinical features in common such as aggressiveness, high recurrence rates and radical management options. Understanding the pathogenesis and biological aspects of these tumors would improve the success of diagnose and treatment procedures. The aim of this study was to exhibit the reasons of high recurrence rates and gr...

PURPOSE The aim of this study was to investigate how clinical features such as sex, age, etiologic factors, and presenting symptoms of odontogenic sinusitis are differentiated from other types of sinusitis. Also, this study was designed to find methods for reducing the incidence of odontogenic sinusitis. MATERIALS AND METHODS A retrospective chart analysis was completed on twenty-seven patien...

Adenomatoid odontogenic tumors are considered, rather than a neoplasia, a benign, hamartomatous epithelial lesion of odontogenic origin . Steensland fi rst described it in 1905; he considered it as a variation of ameloblastoma.1 Stafne, in 1948 described it as an «ameloblastic adenomatoid tumor or adenoameloblastoma»,2 since it presented structures which simulated canals or glands, he therefore...

Actinomycosis is an anaerobic infection that involves the craniofacial region and its colonization has rarely been reported in the developmental odontogenic cysts. In the present report, a case of odontogenic keratocyst (which is now called keratocystic odontogenic tumor) with the colonization of actinomyces is introduced and its significance is discussed.

Introduction: Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare malignant lesion arising within the jawbones, without initial connection with the oral mucosa. This malignant lesion develops from odontogenic epithelium or odontogenic cysts or tumors. Case Report: In this case report, an intraosseous squamous cell carcinoma arising from an odontogenic cyst in a 60-year-old male pati...

The glandular odontogenic cyst is an uncommon developmental odontogenic cyst described as a distinct entity by Gardner et al. in 1988. The Glandular odontogenic cyst occurs more commonly in middle-aged people and has a predilection for the mandible. Only histopathological examinations allow for certain diagnosis of the cyst. The increased recurrence rate can be due to its multilocularity and in...

Odontogenic tumors contain a heterogeneous collection of lesions that are categorized from hamartomas to benign and malignant neoplasms of inconstant aggressiveness. Odontogenic tumors are usually extraordinary with assessed frequency of short of 0.5 cases/100,000 population for every year. The lesions such as odontogenic tumors are inferred from the components of the tooth-structuring contrapt...
