Skeletal complications caused by osteoporosis or bone metastases are associated with considerable pain, increased mortality, and reduced quality of life. Furthermore, such events place a burden on health care resources. Agents that prevent bone resorption, such as bisphosphonates or denosumab, can reduce the risk of skeletal-related events and are widely used in patients with osteoporosis or bone metastases of cancer. Medication-related osteonecrosis of the jaw (MRONJ) is a rare, but potentially serious, adverse event associated with high cumulative doses of bisphosphonates or denosumab...

OBJECTIVE: Intratumoral hypoxia (IH) occurs during cellular proliferation of malignant tumors. This phenomenon is characterized by a decrease in oxygen levels in the neoplastic microenvironment. Throughout this condition, the proteins HIF-1α, NOTCH1, ADAM12, and HB-EGF can be activated, triggering signaling pathways associated with tumor invasiveness through invadopodia formation. This study aimed to evaluate the immunostaining of HIF-1α, NOTCH1, ADAM12, and HBEGF in 19 cases of mucoepidermoid carcinoma (MEC) and 10 samples of salivary glands (control group)...

Although rare, ameloblastic carcinoma (AC) is one of the most common malignant tumors occurring in the odontogenic epithelium. Evidenced-based medical guidelines for AC are not established because AC is a rare type of cancer. However, surgery for AC is the primary initial treatment modality. A few reports suggest that radiotherapy (RTx) is effective for AC; however, the tumor is generally considered to be radioresistant. Furthermore, if RTx is performed for AC, osteonecrosis may occur because most of the ACs arise from the jaw...

BACKGROUND: Coronectomy has become an increasingly prescribed surgical treatment for mandibular third molars that are deemed to pose a risk to the inferior dental nerve. Retention of the roots poses a risk of need for root retrieval in the future if symptoms are present. Long-term outcomes and the symptoms that lead to root retrieval via coronectomy have not been well documented or studied, and this has understandably led to hesitation in some clinicians in offering the procedure. The current series assesses patients who have undergone root retrieval, their reported indications for removal, and the histopathologic status of the removed roots...

OBJECTIVES: Antibody p40, which recognizes exclusively ΔNp63 but not TAp63, has shown diagnostic utility in salivary gland and sinonasal tract malignancies. Although p63 immunophenotypic characterization of odontogenic lesions has been reported, p40 expression has not been previously studied. We aimed to study p40 immunoreactivity in odontogenic tumors (OTs) and odontogenic cysts (OCs) and to investigate possible discriminatory properties of the combined p63/p40 immunoprofile in OTs and OCs...

Superficial mucoceles are a relatively rare variant of common mucoceles and have an unclear etiology. Clinically, they are small, translucent, subepithelial vesicles affecting the oral mucosa in the retromolar region, the lower labial and buccal regions, and the bilateral soft palate. Superficial mucocele is easily misdiagnosed as pemphigoid, bullous lichen planus, herpes lesion, or venous lake when it is concomitant with oral lichen planus (OLP) or lichenoid disorders on the basis of the initial impression...

Cherubism is a rare familial disease of childhood that commonly affects the bilateral mandible and maxilla and typically resolves in adulthood. It has been shown to have a male predilection and has been mapped to the SH3 BP2 gene. Only 2 cases of unilateral cherubism have been documented in the literature; in the first case, the contralateral side was eventually affected. Although rare, unilateral cherubism presents a diagnostic dilemma. This case report describes a unique presentation of unilateral cherubism that progressed to affect the contralateral side and describes some of the considerations in the diagnosis and treatment of unilateral benign giant cell lesions of the jaws...

Gorham disease, a rare disorder of unknown etiology, is characterized by the clinical and radiologic disappearance of bone. Because the etiology is unknown, diagnosis is difficult. Therefore, radiographic manifestations play a vital role in the diagnosis of this disease. Thus far, there has been no completely effective treatment. Most remedies are limited to symptom management. Despite the fact that any bone can be affected, one of the most prevalent sites is the maxillofacial region. In this paper, 2 cases of Gorham disease involving the maxillofacial region are reported, including preoperative and postoperative radiographic features...
