COES: Curing Order Effects on Sealants
Recruiting
Background: Sealants are a great tool in the prevention of caries in the pediatric population. It has been shown that up to 71% of occlusal decay is preventable after a single sealant application in a fissure, and thus is the standard of care due to difficulty for pediatric patients in hygiene, diet, and overall home care until manual dexterity increases. Purpose: This prospective randomized case control study aims to look at the longevity of sealants with bonding agent cured prior to sealant p... Read More

A Study to Estimate How Often Post-stroke Spasticity Occurs and to Provide a Standard Guideline on the Best Way to Monitor Its Development
Recruiting
This study will monitor patients during the first year following their stroke. Stroke is a very serious condition where there is a sudden interruption of blood flow in the brain. The main aim of the study will be to find out how many of those who experience their first-ever stroke then go on to develop spasticity that would benefit from treatment with medication. Spasticity is a common post-stroke condition that causes stiff or ridged muscles. The results of this study will provide a standar... Read More

A Long-Term Study of Elafibranor in Adult Participants With Primary Biliary Cholangitis
Recruiting
The participants of this study will have confirmed Primary Biliary Cholangitis (PBC) and cirrhosis (scarring of the liver). PBC is a slowly progressive disease, characterised by damage to the bile ducts in the liver, leading to a build-up of bile acids which causes further damage. The liver damage in PBC may lead to cirrhosis. PBC may also be associated with multiple symptoms. Many patients with PBC may require liver transplant or may die if the disease progresses and a liver transplant is not... Read More
