INTRODUCTION: Transcatheter arterial embolization (TAE) has gained importance in the management of maxillofacial fractures with life-threating hemorrhage (MFH). However, clinical evidence supporting the use of TAE has not been clearly established in the literature. Therefore, we evaluated the effectiveness of TAE for MFH, based on data obtained from the Japan Trauma Data Bank. METHODS: Patients were identified from Japan Trauma Data Bank entries for the years 2004 to 2014...

Tumour-induced osteomalacia (TIO) is a rare paraneoplastic form of renal phosphate wasting that results in severe hypophosphatemia, defective vitamin D metabolism, and osteomalacia. In the case reported here, maxillary TIO was not diagnosed for 6years, although initial complaints were reported when the patient was 12years old. Meanwhile she suffered from profound growth limitation, pain, weakness, and spontaneous multiple bone fractures, culminating in complete loss of ambulatory ability and severe limitation in daily activities...

Regional odontodysplasia (RO) also known as ghost teeth is a rare developmental anomaly affecting the mesodermal and ectodermal components of teeth with characteristic clinical and radiographic findings. The enamel and dentin are hypomineralized and hypocalcified with short roots and open apices. The affected teeth have an abnormal morphology, meaning they are fragile and thin and liable to fracture and decay. Radiographically, there is a marked reduction in radiodensity with little distinction between the enamel and dentin, hence the term "ghost teeth...

In recent years, there have been a growing number of procedures involving dental implants. Most cases, though, are characterized by bone atrophy, especially horizontal atrophy. This clinical case aims to report a technique for the expansion of the horizontal alveolar ridge. A longitudinal fracture was created in the alveolar ridge to expand the bone, followed by immediate insertion of dental implants along with a particulate allogeneic bone graft. Eight implants were placed in the maxilla, and after 12 months, a surgical reopening was performed, along with rehabilitation with a protocol-type prosthesis, for which a zirconia infrastructure was made...

Maxillofacial injuries can be complex and are clinically important due to their functional and cosmetic significance. Maltreated and missed fractures might cause deformity of the face; thus, accurate evaluation of the fracture provided by X-ray images is critical. In this study, we explore the application of cone-beam computed tomography (CBCT) for diagnosis of severe maxillofacial traumas. A patient with a complex fracture that affects the maxilla, mandible, wall of the maxillary sinus, zygoma, zygomatic arch and nasal bone was diagnosed using 3D reconstruction of CBCT images...

INTRODUCTION: Although regenerative treatment approaches in teeth with incomplete root formation and pulp necrosis have become part of the suggested therapeutic endodontic spectrum, little is known about the effect of orthodontic movement in the tissue that has been regenerated. Furthermore, as the number of adults undergoing orthodontic treatment increases, there is an increasing need to investigate the changes that these tissues may undergo during orthodontic movement. Here we describe the alterations observed after the application of orthodontic forces in a case of an apically root-fractured necrotic immature root that had been managed with regenerative endodontic procedures in the past...

BACKGROUND: Reconstruction of an oromandibular defect presents a considerable surgical challenge. But since the advent of microvascularized free flap reconstructive surgery, outcomes have improved significantly so that today almost any defect may be reconstructed. Recently, virtual surgical planning has reduced surgical time, the morbidity associated with surgery, and surgical precision. OBJECTIVE: This article reports a complex patient with a composite oromandibular defect...

Gnathodiaphyseal dysplasia (GDD; OMIM #166260) is an ultra-rare autosomal dominant disorder caused by heterozygous mutation in the anoctamin 5 (ANO5) gene and features fibro-osseous lesions of the jawbones, bone fragility with recurrent fractures, and bowing/sclerosis of tubular bones. The physiologic role of ANO5 is unknown. We report a 5-year-old boy with a seemingly atypical and especially severe presentation of GDD and unique ANO5 mutation. Severe osteopenia was associated with prenatal femoral fractures, recurrent postnatal fractures, and progressive bilateral enlargement of his maxilla and mandible beginning at ~2months-of-age that interfered with feeding and speech and required four debulking operations...
