PURPOSE: The aim of this study was to evaluate the impact of the reclassification of odontogenic keratocyst (OKC) as a tumor on the prevalence profile of odontogenic cysts (OCs) and odontogenic tumors (OTs). STUDY DESIGN: Two referral Oral and Maxillofacial Pathology services in Brazil were evaluated. All cases diagnosed as OCs or OTs were selected and classified according to the 1992 WHO-classification (cases before 2005 WHO classification of tumors excluding OKC) and the 2005 WHO classification of tumors, going forward including cases of odontogenic keratocyst tumor (KCOT)...

Infections in the maxillofacial complex, including the oral cavity, are common and in certain cases may develop into a severe condition with life threating complications in healthy populations but especially in medical compromised patients (Moazzam et al, 2015). Often, treatment is based on personal experts' experience with limited accuracy obtained from diagnostic laboratory tests. Consequently, "trial and error" attempts are usually implemented until success, in the best case, is accomplished. As a result, there is a pressing need in clinical practice for developing efficient tools for understanding the pathological nature of the infection and its rapid identification based on infection biomarkers...

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 of Malassez, the dental lamina (cell rests of Serres), or the enamel organ. METHODS: We performed a retrospective study of all histologically diagnosed cysts of the orofacial region seen at the Maxillofacial clinic of the Ahmadu Bello University Teaching Hospital, Nigeria, between January 2003 and December 2012...

INTRODUCTION: Mucoceles are benign lesions associated with the pathology of the oral mucosa of minor salivary glands. Two types of cysts are distinguished depending on their pathogenesis. Most often they occur as a result of mechanical trauma and mucus extravasation into tissues or obstruction of the gland ducts. AIM: The aim of the study was to present our own experiences regarding mucoceles of minor salivary glands in the oral cavity taking into account how frequently the individual types of cysts occur in children...

Extragnathic xanthomas are seen in the bones or as soft tissue masses. They are often associated with hyperlipidemia and are considered as reactive or metabolic lesions. Only 19 cases of xanthomas of the jaws have been reported so far in the English literature. A total of ten cases of central xanthoma of the jaw bones were identified from the Oral and Maxillofacial Pathology biopsy services of the University of Washington and the Tufts University School of Dental Medicine, between the years 2000-2016. The demographic and clinical information on these cases was tabulated logically on the basis of age, gender, location and presence or absence of symptoms, extragnathic lesions and serum hyperlipidemia...

Pathological conditions can give rise to calcifications within oral mucosa representing either a local or systemic disturbance. Inflammation, trauma, debris acting as nidus and vascular lesions have been attributed as principal causes for occurrence of calcifications within the oral mucosa. Occurrence of multiple calcified thrombi (phleboliths) is considered pathognomonic for hemangiomas and vascular malformations in the oral and maxillofacial region. Isolated occurrence of phlebolith in oral mucosa though very rare, especially without any underlying vascular lesions, can be diagnostically challenging...

Background. The inferior alveolar canal should be examined as a significant anatomical landmark, particularly in the posterior body and ramus of the mandible, for dental and surgical procedures. In the present study, the effects of two pathological lesions, ameloblastoma and keratocystic odontogenic tumor, on canal displacement were investigated. Methods. This study had a single-blinded design. Twenty-six patients with lesions in the mandible referred to Imam Reza Hospital, Tabriz, Iran, were studied in two equal groups (13 patients with a histopathological diagnosis of ameloblastoma and 13 with a histopathological diagnosis of odontogenic keratocyst)...

This study describes a case of myxoid chondrosarcoma of the mandible in a 22-year-old male patient. A tumour in the buccal gingiva of the lower left premolar region had been identified 2 years earlier. Whole-jaw panoramic radiographs showed a hypodense shadow in the mesiodistal area near the roots of teeth 34 and 35. A maxillofacial computed tomography scan revealed a mass in the lower left premolar soft tissue, with a shadow indicating bone destruction, a clear boundary and uniform density. The preliminary diagnosis at the outpatient department was 34-35 epulis...

Intraoperative navigation systems are widely used in ENT, oral and maxillofacial, and neurosurgery. The benefits of such systems have been demonstrated in various applications, including intracranial and skull base surgery. Intraoperative shift, "brain shift" and changes in anatomy caused by the surgical procedure itself impair the accuracy of navigation and represent factors limiting its application, particularly in glioma and metastatic brain surgery. For this reason, intraoperative imaging was incorporated into neurosurgery...

Paediatric odontogenic myxoma (OM) is a rare pathological condition in the oral and maxillofacial region. There has been much debate in the literature regarding the preferred method of treatment; however due to the rare nature of this disease, definitive algorithms of management are yet to be determined. A case series of eight paediatric patients with OM is presented. Six of the lesions were in the maxilla and two were mandibular lesions. The patients were aged between 2 and 18 years. Treatment ranged from excision and the application of Carnoy's solution to segmental resection and reconstruction...

Background. Facial aging is a dynamic process involving both soft tissue and bony structures. Skin atrophy, with loss of tone, elasticity, and distribution of facial fat, coupled with gravity and muscle activity, leads to wrinkling and folds. Purpose. The aim of the study was to evaluate microporous tricalcium phosphate (β-TCP) and autologous platelet gel (APG) mix in mice for oral and maxillofacial soft tissue augmentation. The hypothesis was that β-TCP added with APG was able to increase the biostimulating effect on fibroblasts and quicken resorption...
