INTRODUCTION Odontogenic tumors (OTs) are a heterogeneous group of lesions that are derived from odontogenic apparatus comprised of odontogenic epithelium, ectomesenchyme, and/ or mesenchymal elements. The OTs show marked geographical variation. This study was conducted to analyze the epidemiology and clinicopathological presentation of OTs based on age, sex, and site. MATERIALS AND METHODS T...

A calcifying cystic odontogenic tumor (CCOT) is a proliferation of odontogenic epithelium and scattered nests of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass. It was previously described by Gorlin et al in 1962 as a calcifying odontogenic cyst. Dentigerous cysts are developmental odontogenic jaw cysts, commonly manifesting in the second and third...

Background: Odontogenic myxoma is a rare slow growing, benign, locally aggressive tumor of ectomesenchymal origin with or without odontogenic epithelium, comprising 3% to 6% of all odontogenic tumors. It appears to originate from dental papilla, follicle, or periodontal ligament in mandible and less commonly the maxilla. These usually present in second or third decades with marked female predil...

Odontogenic cysts originate from remnants of the tooth forming epithelium in the jaws and gingiva. There are various kinds of such cysts with different biological behaviours that carry different patient risks and require different treatment plans. Types of odontogenic cysts can be distinguished by the properties of their epithelial layers in H&E stained samples. Herein we detail a set of image ...

BACKGROUND Odontogenic cysts are defined as those cysts that arise from odontogenic epithelium and occur in the tooth-bearing regions of the jaws. Cystectomy, marsupialization or decompression of odontogenic cyst are treatment approach to this pathology. The aim of this study was to evaluate the effectiveness of the decompression as the primary treatment of the cystic lesions of the jaws and th...

ntroduction: Odontogenic fibromas (OFs) were defined in the latest classification of the World Health Organization (WHO) as a uncommon neoplasm characterized by an erratic quantity of inactive odontogenic epithelium in a rather-mature fibrous stroma. [1] OF is considered to be an " Elusive and controversial tumor " due to its rarity and the uncertainty. [2] It is a benign neoplasm, representing...

Odontogenic keratocyst is now designated by the World Health Organization as a keratocystic odontogenic tumor (KCOT). According to recent reports Wnt pathway and ß-catenin are involved in the pathogenesis of the majority of odontogenic and neoplastic lesions. The aim of this study was to evaluate the expression of ß-catenin in KCOT and compare it with those of dentigerous cyst and ameloblastoma...

INTRODUCTION The adenomatoid odontogenic tumor (AOT) associated with odontoma has been described as a new entity with overlapping features of adenomatoid-like structures and odontoma. Presentation of the case: We report the second case of AOT associated with odontoma in the posterior maxillary region. A 22-year-old patient presented expansion of the vestibular and palatine cortical wall of maxi...

Background: Odontogenic tumors arise from remnants of embryonic tissue destined to develop into teeth & associated structure. They originate from remnants of odontogenic epithelium, mesenchymal or combination of cellular elements that comprise the toothforming apparatus, clinical behaviour ranges from hematoma like proliferation to benign and invasive neoplasm Objective: Purpose of study to ana...

BACKGROUND Odontogenic cysts are those which arise from the epithelium associated with the development of teeth. Some odontogenic cysts were found to have special biological features that make them distinct from other lesions. This study was conducted to detect the immunoepxression of laminin-1 and Ki-67 in both radicular cysts (RCs) and keratocystic odontogenic tumors (KCOTs) and to examine th...
