Filter by:Introduction: osteonecrosis of the femoral head is a potentially crippling disorder, which mainly affects the young adults. Core decompression has been used for the treatment of the osteonecrosis of the femur head since was published by Ficat and albert, and by HUNGERFORD and Lennox. hyperbaric oxygen therapy is a suggestive joint preserving treatment for symptomatic prolapse stage of osteonecrosis of the femur head. Aims and objectives: to compare the clinical (functional) outcome of core decompression versus hyperbaric oxygen therapy in pre collapse stages of idiopathic avascular necrosis of the femur head. Material and methods: Mixed Retrospective and prospective study for all case of pre collapse of avascular necrosis of femoral head(AVNHF) underwent either hyperbaric oxygen therapy or Core decompression augmented with bone substitute in HAMAD General Hospital Anticipated outcome: Hyperbaric oxygen treatment associated with better outcomes at preserving the joint and associated with less complications than surgery
The aim of this study was to evaluate the effectiveness of tactile sense, digital periapical radiograph and two different varieties of electronic apex locators at working length determination in primary molars. A total of 30 infected mandibular primary second molar teeth in twelve children aged between 5 and 8 years were included in this study. Working length determination was performed using tactile sense, radiographic method and two different varieties of electronic apex locators (ProPex Pixi® and Ipex®) separately.

Earlier, it was believed that successful regeneration cannot be achieved once tooth has become infected. However, recent studies suggest that regenerative endodontics may in fact be possible in teeth with pulpal necrosis and periapical pathology. The primary goal in regenerative procedure is to eliminate clinical symptoms and resolve apical periodontitis. The blood clot acts as a scaffold, and the growth factors inside recruit stem cells, most likely from periapical papilla. But unfortunately, the erythrocytes in the clot of the blood column undergo necrosis, affecting its properties so the blood column is augmented by the use of different types of scaffolds. Platelet-rich fibrin is classified into four types (Standard PRF, Injectable PRF, Advanced PRF and Concentrated Growth Factor CGF) according to speed and time of centrifuge with the overall aim to increase the number of platelets and leucocytes
The purpose of the study is to evaluate the effect of Mesenchymal Stromal Cell (MSC) implantation on pulp and periapical regeneration of immature teeth with pulp necrosis and chronic apical periodontitis. BACKGROUND: - Post-traumatic pulp necrosis prevents root development in children and adolescents. - The multipotent ability of MSC to differentiate into bone-forming cells (osteoblasts) and dentin-forming cells (Odontoblast) has allowed the development of protocols to induce dental pulp regeneration in preclinical models and patients with immature teeth with pulpal necrosis. IMPACT: - Worldwide, post-traumatic pulp necrosis in children and adolescents constitutes a health problem in the endodontic area. - Treatment with MSC would provide an effective therapeutic alternative to patients with pulp necrosis and incomplete root formation. - The possible pulp and periapical regeneration of immature teeth induced by MSC would have a huge impact on the treatment of these patients. Eligibility for EMC implant study Age: 6 to 16 years Sex: Male or Female Healthy volunteers accepted: NO. TREATMENT GROUPS: In the present study, the implantation of MSC will be performed in patients with immature teeth with pulpal necrosis with apical periodontitis, who will receive the appropriate endodontic treatment (according to the guidelines of the American Association of Endodontics) and implantation of allogeneic BM-MSC . This group will be compared with the history made in the Postgraduate Endodontics of the Universidad Central de Venezuela (UCV) and with international case series made by revascularization. Clinical follow-up of each patient: 1. Clinical controls (facial evaluation, gingival evaluation, apical palpation, horizontal and vertical percussion, cold and heat sensitivity tests) will be carried out on days 0, 7, 30, 90, 180 and 364. Additionally, a clinical evaluation will be carried out at the two years post-implantation of MSC. 2. Radiological controls will be carried out on days 0, 7, 30, 90, 180 and 364. Additionally, they will be carried out two years post-implantation of MSC. 3. A tomographic evaluation will be performed when was evident periapical repair in a periapical radiograph. To measure root formation, root canal narrowing and verification the periapical repair in 3D.
The EXAMINATION trial was a superiority trial that compared everolimus-eluting stents (EES) versus bare-metal stents (BMS) in an all-comer ST-segment elevation myocardial infarction (STEMI) population. The patient-oriented endpoint was not superior at 1-year, but it was at 5-year. However, very-long term follow-up is unknown. The study had an independent Clinical event Committee (CEC). All events were adjudicated by an independent clinical committee, according to the Academic Research Consortium 1.
This clinical study will verify the clinical and radiographic performance of the prosthesis when used in human subjects over a period of 10 years. All complications will be documented.
The investigators explore the role of the complement pathway and T helper 1 immune response in clinical response to Candida immunotherapy via complement component and tumor necrosis factor, respectively.
The current study evaluates the rotational One Shape single-file system regarding clinical and radiographic outcomes in root canal treatment of infected primary molars. This randomized clinical trial was carried out on 94 primary molars on children in the age group from 4 to 6 years. The teeth selected for this study were randomly assigned into 2 groups according to the used endodontic preparation system. Group I: 47 primary molars were instrumented with One Shape rotational single-file system. Group II: 47 primary molars were instrumented with stainless steel K-files. All teeth were evaluated clinically and radigraphically for 12 months with periodic recall at 3, 6 and 12 months.
The aim of the present study is to assess clinically and radio-graphically the regenerative potential of immature permanent teeth with necrotic pulp using blood clot and Platelet rich fibrin scaffolds.
