Active clinical trials for "Necrosis"

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 primary purpose of this study is to measure the postoperative changes in bone mineral density, comparing the Taperloc Complete Reduced Distal Microplasty stem and the standard length Taperloc Complete Reduced Distal stem.

Both methods tested in this study disinfect the non-vital root canals and induce blood clot formation inside the root canal. One method places calcium hydroxide inside the root canal after disinfection and the blood clot is induced four weeks later. The other method performs disinfection and induction of blood clot in one appointment. The investigators hypothesize that both methods will obtain the same success rate in eliminating infection, increase in root length and canal walls thickness.

This study was initiated to investigate the impact of the computer based image free navigation on the precision of the cup implantation. The implantation of the acetabular component (cup) is known to be a critical step in hip endoprosthetics. The cup position influences significantly the function, the absence of pain and the longevity of the artificial hip joint. The image free navigation system OrthoPilot is used to control the positioning of the cup during surgery.

This study compares the posterior approach to the anterolateral approach using the ReCap® Total Hip Resurfacing System.

Methods to reduce the revision rate of total hip arthroplasties (THAs) because of wear-related issues are important to examine, particularly because younger patients have a disproportionately high risk of revision. The investigators hoped to follow up patients and see if long-term Harris hip scores and WOMAC scores better in younger patients with a ceramic-on-ceramic (COC) THA compared with those with a ceramic-on-highly-cross-linked polyethylene (COP) THA.

This study compared the efficiency of pulp revascularization and MTA apexification in the treatment of patients with necrotic immature anterior teeth.

The purpose of this prospective study is to evaluate Zimmer® iASSIST™ with respect to radiographic, clinical and economic outcomes and compared to conventional instrumentation in primary total knee arthroplasty (NexGen or Persona knee implants).

Prospective, randomized controlled trial comparing Endoscopic Ultrasound (EUS) Guided cystogastrostomy or cystoduodenostomy and endoscopic necrosectomy to minimally invasive surgical necrosectomy, in patients with necrotizing pancreatitis.

Non-surgical root canal therapy (RCT) represents a standard of treatment that addresses infected pulp tissue in teeth and protects against future infection while preserving the tooth for the patient for mainly cosmetic purposes. RCT is offered as the better cosmetic, cheaper, and less time intensive treatment option for a patient compared to those of dental implantation. Dental implantation is the alternative to RCT, and they are both originally offered at the time of the initial consultation. RCT involves non-surgically removing dental pulp comprising blood vessels and nerve tissue, decontaminating residually infected tissue, and using a filler material to replace the non-surgically created space where the pulp was removed. Currently, standard of care treatment for RCT utilizes gutta-percha as the root canal filling material. Our research group has previously demonstrated NDGP's improvement in tensile strength compared to those of gutta-percha. This research studies a new type of filler, gutta-percha modified by the addition of nanodiamond material (NDGP). This is an equivalence study of NDGP and standard gutta-percha administration.
