As the main inorganic component of xenogenic bone graft material, bone-derived biological apatite (BAp) has been widely used in implant dentistry, oral and maxillofacial surgery and orthopedics. However, BAp produced via calcination of animal bones still suffers from some drawbacks, such as insufficient mechanical strength and inadequate degradation rate, which impede its application. Fluoride is known to play important roles in both physiological and pathological processes of human hard tissues for its double effects on bones and teeth...

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...

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...
