Active clinical trials for "Necrosis"

Evaluate E1 wear, Clinical Performance of E1 liner in THA in Korean Patient Population

Children often damage their front teeth. In approximately 6% of cases, the nerve inside the affected tooth dies (becomes 'non-vital') and natural root development stops. In these cases, the tooth requires a root canal treatment in order to prevent problems such as pain and dental abscesses from arising. However, because the roots of these young teeth are not fully formed, they are weaker and prone to fracture. In addition, root canal treatment is difficult because a root canal filling cannot be placed in a tooth which is not yet fully formed, due to the fact that the root has an 'open' end. To enable root canal treatment to be carried out, a 'barrier' must be placed at the end of the 'open' root. This can be done using materials called Calcium Hydroxide or Mineral Trioxide Aggregate (MTA). These materials are placed inside the root and sealed into the tooth. However, although they help to provide a barrier, they do not help to strengthen the walls of the root. Treatment with these materials requires multiple visits to the dentist, over a period of up to 18 months. There is evidence to suggest that an alternative treatment involving 'revascularisation' (recovery of the blood supply to the tooth) and the use of a triple antibiotic paste allows 'natural' root growth to restart, and also strengthens the walls of the root. Treatment can often be carried out in just two visits. The aim of this study is to discover whether there is a difference between one of two methods of treating non-vital teeth with open ends. It is thought that there will be no significant differences seen between the results of the two techniques. Children with teeth that fall into this category and require root canal treatment will be given one of two treatments, both of which aim to treat infection, close the root end and to allow healing to take place. Teeth will receive one of the following methods of root treatment: Revascularisation (recovery of the natural blood supply to the tooth) following placement of an antibiotic paste into the tooth root. The aim of this treatment is to allow 'natural' root growth to restart. Root growth will allow the tooth to form at barrier at the end of the root. No root canal filling will then be necessary. Closure of the open root end by placement of an artificial barrier at the end of the root so that a root canal filling can then be placed. This will be done with a dental material called Mineral Trioxide Aggregate (MTA). Non-vital teeth with an open end are routinely treated in this way at Liverpool Dental Hospital.

The purpose of this study is to determine the treatment outcomes in permanent teeth with necrotic pulp and immature root development that undergo a regenerative procedure using a triple antibiotic paste (ciprofloxacin, metronidazole, minocycline) versus a double antibiotic paste (ciprofloxacin, metronidazole)compared to the commonly used mineral trioxide aggregate (MTA) apexification treatment.

The study will evaluate the clinical performance of the rotating platform and fixed bearing implants through patient questionnaires, outcomes scoring and radiographic assessment.

This study is a clinical evaluation of survivorship of an acetabular cup system after total hip replacement using patient examinations and questionnaires.

Randomized study. Initially, 3 patients will be entered on Arm I as a pilot feasibility study and to standardize the technical aspects of the study. Subsequently, all patients are randomized to Arms I and II. Arm I: Regional Hyperthermia plus Regional Single-Agent Chemotherapy. Hyperthermic intravenous limb perfusion, HILP; plus Melphalan, L-PAM, NSC-8806. Arm II: Regional Hyperthermia plus Regional Single-Agent Chemotherapy and Biological Response Modifier Therapy. HILP as in Arm I; plus L-PAM; and Tumor Necrosis Factor (Knoll), TNF, NSC-635257; Interferon gamma (Genentech), IFN-G, NSC-600662.

The primary objective of this study is to evaluate clinical performance for the commercially available Persona TM Tibia used in primary cementless tibia total knee arthroplasty.

The study is a multi-center, prospective, non-controlled, consecutive cohort post market surveillance study. The objective of this study is to obtain survival and outcome data on the Continuum Metal Bearing System in primary total hip arthroplasty.

The aim of the current study is to compare a newly introduced material which is a combination of triple mix antibiotics paste and anti-hyperlipidemia drug simvastatin, the new material is named 3MIX-TATIN & will be compared to triple antibiotic paste for management of necrotic primary molars by using lesion sterilization and tissue repair LSTR technique.

The present study was conducted to test whether pulp-like tissue can be regenerated in mature teeth with closed apex? And whether the size of the apical diameter affects the success of REPs? And whether Magnetic resonance imaging (MRI) can be used to quantitatively assess the vitality of the regenerated pulp-like tissue.
