This study tests a new method using i-PRF (a blood concentrate) during immediate dental implant placement in damaged tooth sockets. The goal is to improve gum appearance and bone thickness around the implant. The study involves 24 adults with a hopeless front tooth and a healthy …

This study tests whether a melatonin-loaded gel, made from your own blood, can improve gum health in people with stage II periodontitis. About 60 adults with mild to moderate gum disease will receive the treatment. The main goal is to see if it helps reattach gums to teeth.

This study compares two materials—enamel matrix derivative and amniotic membrane—used in regenerative dental treatment for children aged 7-12 with non-vital immature front teeth. The goal is to see which material better promotes root growth and healing of infection. 39 participan…

This study tests whether adding a gel made from the patient's own blood (injectable platelet-rich fibrin) to a standard bone graft helps heal deep gum defects better than the bone graft alone. Twenty adults with advanced gum disease (stage III) and deep pockets will receive the c…

This study tests a surgical technique for children aged 3-15 with wrist fractures that didn't heal properly with a cast. The method uses a flexible nail and a wire to better align the bone. The goal is to see if this approach reduces pain and improves healing.

This study tests three different materials—amniotic membrane, putty mineral trioxide aggregate, and biodentine—to treat deep cavities in children's permanent molars that are still growing. The goal is to help the tooth root finish developing and avoid the need for more complex tr…

This study compares two types of implant-supported dentures—regular and 3D-printed—using two different attachment systems. Twenty adults with no teeth will try both denture designs to see which stays in place better, lasts longer, and feels more comfortable. The goal is to improv…

This study looks at whether a hands-on therapy called myofascial release, alone or with exercise, can help people with cervicogenic headaches (headaches caused by neck problems). About 100 adults aged 20-55 will receive the therapy and have their neck curve measured on X-ray. Res…

This study compares two devices—a self-activated leaf expander and a William's expander—to widen a collapsed lower jaw in 16 teenagers aged 12-16. The goal is to relieve mild to moderate crowding without removing teeth. Participants must have good oral health and no prior orthodo…

This study compares two techniques—piezocision (a minor surgical procedure) and injectable platelet-rich fibrin (using your own blood components)—to see which speeds up canine tooth movement during orthodontic treatment. About 16 people aged 14-22 who need premolar extraction and…

This study looks at whether applying a chemical called dimethyl sulfoxide (DMSO) to older, worn-down teeth helps dental fillings bond more strongly and leak less. Researchers will test this on 30 people aged 50 to 75 who have non-cavity tooth lesions. The goal is to improve the s…

This study looks at two different types of lower dentures held in place by dental implants in adults aged 60-70. The goal is to see which design distributes bite force more evenly and stays more securely in the mouth. Researchers will use special devices to measure bite balance a…

This study looks at published research to compare surgical and non-surgical treatments for frozen shoulder (adhesive capsulitis), a condition causing pain and stiffness. The goal is to see which approach works better based on existing studies. No new patients are being treated; 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 and a Class II bite. About 24 participants will receive one of the two expanders, and the amount of tooth movement will be measured with …
