BACKGROUND: Dental disease, trauma and maxillofacial surgeries can cause alveolar bone defects. Among different kinds of treatment, autogenous bone grafts is accepted as a golden standard. On the other hand, because of limitation of treatment with autogenous bone grafts, osteogenic cells derived from stem cells are suggested. OBJECTIVES: The aim of this study was to compare the mean density of ...

Recent research suggests ACL reconstruction does not restore tibial rotation to normal levels during high demand activities when a bone-patellar tendon-bone graft is used. We asked if an alternative graft, the semitendinosus-gracilis (ST/G) tendon graft, could restore tibial rotation during a high demand activity. Owing to its anatomic similarity with the normal ACL we hypothesized the ST/G gra...

OBJECTIVES There have been no reported studies of the association between parity and cartilage in young individuals. The aim of this study was to describe the association between parity, cartilage volume and cartilage defects in women aged 31-41 years. METHODS Cross-sectional study of 144 women, mean age 36 years and BMI 25 kg/m(2), who were participants in an established prospective study. P...

Introduction Over the past years, in order to anchor a prosthetic component to bone, different cements based on selfpolymerizing poly (methyl methacrylate) (PMMA) have been widely used as commercial synthetic biomaterials. The aim of this study was to evaluate the influence of a PMMA-based bone cement (Palamed® G40) on the viscoelastic behaviour of spongy bone from proximal human tibial epiphys...

introduction: bite wing radiographs are indicated in children with closed posterior contacts. given the fact that nowadays bitewing radiographs are taken using both paper loop and film holder, the aim of this study is the evaluation of acceptance and diagnostic quality of two methods. materials and methods: this study is a sort of diagnostic accuracy test that was performed on 20 6-8 year old c...

OBJECTIVE To anatomically evaluate the femoral origin and tibial insertion of the anteromedial and posterolateral bands of the anterior cruciate ligament. METHODS We studied eight cadaver knees as for the following: in the femur, distance from the center of the anteromedial band to the deep cartilage and the ceiling; also in the femur, distance from the center of the posterolateral band to th...

Purpose:Human amniotic fluid contains several growth factors and hyaluronic acid. It has positive effect in healing the tendon, nerve bone injuries. Human membrane effects on is also used for skin burns complex wounds. We hypothesized that human have stimulating fracture healing. The aim of this study to investigate rat tibial model.
