This study tests whether adding a natural blood concentrate (injectable platelet-rich fibrin) to a standard bone graft helps repair deep gum defects better than the graft alone. Twenty adults with advanced gum disease (stage III) and deep pockets will receive the combination trea…

This study tests whether a melatonin-loaded gel, made from your own blood, can improve gum health in people with stage II periodontitis (moderate gum disease). Sixty adults with gum pockets less than 5 mm will receive the treatment, and researchers will measure changes in gum att…

This study looks at a new surgical technique for children aged 3-15 with wrist fractures that didn't heal properly with a cast. The method uses flexible nails and a wire to hold the bone in place. The goal is to see if it safely improves bone alignment and reduces pain.

This study looks at two different types of lower dentures that are held in place by dental implants. The goal is to see which one helps people chew better and stays in place more securely. The study involves 24 adults aged 60-70 who have no teeth in their lower jaw. Researchers w…

This study compares two devices—the self-activated leaf expander and William's expander—for widening a collapsed lower dental arch in teenagers aged 12 to 16. The goal is to see which expander better increases the width between the lower canine teeth. Participants must have mild …

This study looks at published research to compare surgery and non-surgical treatments for frozen shoulder (adhesive capsulitis), a painful condition that limits arm movement. The goal is to see which approach works better for pain and motion. Only one person is enrolled because i…

This study compares two dental devices—one with tiny screws and one without—to see which moves back molars better in people with crowded teeth. About 24 participants with specific bite problems will be measured using 3D X-rays. The goal is to find out which device works more effe…

This study looks at whether applying dimethyl sulfoxide (DMSO) to older, worn-down teeth before adding a filling helps the filling bond more strongly and prevents tiny leaks. Thirty adults aged 50 to 75 with non-cavity tooth lesions at the gum line will be treated and evaluated u…

This study compares two methods—piezocision (a small gum surgery) and injectable platelet-rich fibrin (using your own blood platelets)—to see which speeds up moving a canine tooth after a premolar is removed. Sixteen people aged 14-22 with crowding or protrusion will take part. T…
