Chronic non-suppurative osteomyelitis (CNSO) is a chronic bone disease and may be associated with a reparative periosteum entity called proliferative periostitis (PP). This condition rarely affects the maxillofacial region. Mandibular cases were already described for an infectious dental cause, often with an "onion skin" radiographic aspect, but some rare reported cases showed no obvious etiology. They represent a challenge for diagnosis because of possible misdiagnosis leading to unsuccessful or inappropriate treatment attempts...

Descriptions of several oral, maxillofacial and dental conditions/diseases exist for a variety of captive large felids, but little is reported on the pathology of free roaming large felids. Apart from focal palatine erosions (FPEs) as initially described by Fitch and Fagan (1982) and some reference to absent incisor teeth, few data exist on diseases affecting the oral, maxillofacial and dental structures of cheetahs (Acinonyx jubatus), regardless of their captivity status. This study reports 18 different conditions affecting the teeth, bone and oral cavity soft tissue of cheetahs, based on initial assessment of 256 animals over 11 years (2002-2012) in South Africa and Namibia...

Langerhans cell histiocytosis (LCH) is a childhood pathology with a peak of incidence ranging from 1 to 4 years of age, though diagnosis is often made in adult age. LCH is clinically classified into three types: eosinophilic granuloma, Hand-Schuller-Christian disease and Abt-Letterer-Siwe disease. We report a case of Hand-Schüller-Christian disease with diabetes insipidus, skull and maxillary involvement in a 16-year-old boy referred to our observation for gradual increase in mobility of the teeth and subsequent gradual loss of the second premolars and the first molars of the upper jaw...

Introduction: Odontogenic tumors (OTs) are a group of heterogeneous lesions derived from epithelial or ectomesenchymal tissues or both, which are part of the tooth-forming apparatus. They range from hamartomatous or nonneoplastic tissue proliferations to malignant neoplasms with metastatic capacity. OTs are comparatively rare, comprising about 4.79% of all oral and maxillofacial biopsy specimens diagnosed. Several retrospective studies carried out in Africa, Asia, Europe and America, show that differences exist in the relative frequency of the various histologic types...

Background: Research methodology in oral and maxillofacial pathology has illimitable potential. The tissue processing involves many steps of which one of the most important step is "Clearing," which is a process of replacing dehydrant with a substance which is miscible with embedding medium or paraffin wax. Xylene is one of the common clearing agents used in laboratory, but it is also hazardous. The main aim of this study is to substitute conventionally used xylene by a mixture of kerosene and xylene in clearing steps without altering the morphology and staining characteristics of tissue sections...

3D visualizations of volumetric data from CT have gained widespread clinical acceptance and are an important method for evaluating complex anatomy and pathology. Recently, cinematic rendering (CR), a new 3D visualization methodology, has become available. CR utilizes a lighting model that allows for the production of photorealistic images from isotropic voxel data. Given how new this technique is, studies to evaluate its clinical utility and any potential advantages or disadvantages relative to other 3D methods such as volume rendering (VR) have yet to be published...

Introduction: Ezrin, also known as cytovillin, is a member of the ERM family of protein. Ezrin cross-links actin filament with the plasma membrane. They are involved in the formation of microvilli, cell-cell adhesion, maintenance of cell shape, cell motility, and membrane trafficking. Recent analysis reveals their involvement in signaling pathways. Ezrin is highly expressed in several types of human cancers, and correlation between its immunoreactivity and histopathological data as well as the patient outcome has previously been studied...

BACKGROUND: Osteomas are infrequent benign bone tumors of uncertain etiology. They are usually situated at extremities and their occurrence in the jaws is relatively rare. There are 3 types of osteoma: central, peripheral, and extraskeletal. Preoperative presumptive diagnosis is performed by means of radiography using orthopantomographs, computerized tomographs, or cone beam scans. Treatment is surgical and consists of careful exeresis and curettage of the adjacent tissue. In recent years, piezoelectric surgery has been used to treat bone pathologies in the maxillofacial area, orthopedic surgery, and neurosurgery...

Maxillofacial defects are complex lesions stemming from various etiologies: accidental, congenital, pathological, or surgical. A bone graft may be required when the normal regenerative capacity of the bone is exceeded or insufficient. Surgeons have many options available for bone grafting including the "gold standard" autologous bone graft. However, this approach is not without drawbacks such as the morbidity associated with harvesting bone from a donor site, pain, infection, or a poor quantity and quality of bone in some patient populations...
