Salivary gland related bone defects or Stafne bone defects are asymptomatic bone cavities in the mandible caused by impingement by the salivary glandular tissue. All the three major salivary glands are in approximation with the mandible and depressions with each can produce radiolucent defects on the surface of the mandible. These bone defects or depressions are categorized as anterior lingual ...

Silastic implants used to augment the chin during cosmetic surgery may cause erosive bone changes and complications. We describe the radiologic appearance of these changes and the dental CT reformatting programs by which they may be assessed. Multiplanar CT scans of four patients with Silastic chin implants were evaluated retrospectively for implant density, presence and size of bone defects, r...

objectives : bone assessment is essential for diagnosis, treatment planning and prediction of prognosis of periodontal diseases. however, two-dimensional radiographic techniques have multiple limitations, mainly addressed by the introduction of three-dimensional imaging techniques such as cone beam computed tomography (cbct). this study aimed to assess the accuracy of cbct for detection of marg...

BACKGROUND Treatment of osteonecrosis continues to be a challenging problem. The replacement of necrotic bone with graft materials that promote osteogenesis and angiogenesis may provide better outcomes for early stage disease. In this study, genetically engineered bone-marrow stem cells were used to enhance repair of a defect in the distal aspect of the femur. METHODS Cloned bone-marrow stem ...

Introduction: Subchondral bone defects in the proximal tibia are commonly encountered with tibial plateau fractures. Bone defects and grafting treatments affect knee mechanics but the effects are not well understood. Changes in subchondral strain affect cartilage stress which likely contributes to posttraumatic arthritis. Historically, investigators have had to use analytical models to study tr...

BACKGROUND Statin can induce the gene expression of bone morphogenetic protein-2. Red yeast rice (RYR, Hongqu), i.e. rice fermented with Monascus purpureus, contains a natural form of statin. This study demonstrates the effects of RYR extract on bone formation. METHODS Bone defects were created in the parietal bones of two New Zealand white rabbits. In the test animal, two defects were grafte...

Objective(s): Autologous bone transplantation known as the “gold standard” to reconstruction of osseous defects has known disadvantages. This study was designed to explore the effects of hydroxy-apatite/tricalcium-phosphate (HA/TCP) and platelet-rich plasma (PRP) on the osteogenesis ability of human adipose-derived mesenchymal stem cells (hAdMSCs) in vitro and in vivo. Materials and Methods: hA...
