This study tests whether placing omega-3 fatty acids inside a damaged tooth can help it regrow root length and dentin, compared to the standard method of inducing bleeding. Twenty patients aged 6 to 28 with immature permanent teeth that have died due to injury or decay will be tr…

This study tests a new type of dental implant that is shaped like a natural tooth root (bio-implant) against the usual screw-type implant. The goal is to see which works better for supporting a partial denture in people missing back teeth on both sides of the lower jaw. Eight hea…

This study tests a new digital brace (Digital Bonded Reverse Twin Block) for children aged 8-11 with a mild underbite. The brace is custom-made using a digital scan and aims to improve the bite and facial profile. 21 children will be treated and followed to see how well the brace…

This study tests whether a collagen patch made from pig tissue can help improve the gum tissue around dental implants in 20 adults aged 25-50 with thin gums. The patch is placed during implant surgery to see if it helps the gums heal better and stay healthy. Researchers will chec…

This study compares two types of dental prostheses—milled bar and screw-retained—for people with severe upper jawbone loss who receive custom subperiosteal implants. Twenty participants will be randomly assigned to one of the two prostheses and followed for one year. The goal is …

This study tests two methods of placing soft tissue grafts (from the cheek or the roof of the mouth) over dental implants placed right after tooth removal. The goal is to see which technique leads to better healing and less bone loss around the implant. Twenty healthy adults with…

This study compares two types of dental implants (basal vs. compressive) in 14 people with severe jawbone loss. Both implant types are placed in the front part of the lower jaw and immediately fitted with a permanent denture. Researchers will check bone health, bone levels, and i…

This study tests whether oleanolic acid, a natural plant compound, works better than standard medicines (calcium hydroxide and Ledermix) when placed inside a root canal. The goal is to reduce bacteria and inflammation in teeth with infection. Thirty-six adults with infected singl…

This study looks at whether a bone graft putty added to dental implants helps bone and gum heal better after a tooth is removed. About 72 people with a damaged front tooth will get an implant with or without the putty. The goal is to see if the putty improves implant stability an…

This study tests whether applying fluoride varnish to one side of the mouth can prevent white spot lesions (early cavities) during clear aligner treatment. Twenty-five people aged 16-24 with mild crowding will have one side treated with fluoride varnish and the other side left un…

This study tests whether using a fluoride-releasing composite resin for aligner attachments can prevent white spot lesions (early cavities) during clear aligner therapy. Twenty-four people aged 16-24 with mild crowding will have one side of their mouth get the fluoride resin and …

This study tests whether mirror therapy can improve arm function and lessen pain in people who have had a stroke. 72 participants with weakness on one side will be randomly assigned to receive mirror therapy or standard care. The goal is to see if this simple, non-invasive techni…

This study looks at two simple ways to help children feel less anxious and in less pain when getting a tooth pulled. One method uses a fun video to distract them, and the other uses gentle pressure on a specific point on the hand. The study will include 69 healthy children aged 5…

This study looks at whether adding dexmedetomidine to standard spinal anesthesia can help people feel less pain for longer after knee surgery. About 100 adults having elective knee surgery will take part. The main goal is to measure how long it takes before they need pain medicin…

This study compares clear aligners to traditional braces for treating mild to moderate dental crowding in adults with a normal jaw relationship. Twenty-four participants will be randomly assigned to one of the two treatments. The main goal is to see how each method affects the bo…

This study tests a less invasive surgical approach for treating persistent tooth infections. Instead of removing all infected tissue and using stitches, surgeons remove only part of the tissue and seal the area with a medical glue. The goal is to see if this method reduces pain, …

This study tests whether wearing a custom mouth splint and getting a granisetron injection into the jaw muscle reduces pain from temporomandibular disorders (TMD) better than the splint alone or with lidocaine. About 48 adults with jaw muscle pain will be followed for 6 months. T…

This study compares two simple techniques—applying manual pressure or using a ShotBlocker device—to reduce pain from insulin injections in children aged 6 to 12 with type 1 diabetes. About 108 children will rate their pain during and right after the injection. The goal is to find…

This study tests whether a structured educational program can help urostomy patients improve their self-care skills and overall life satisfaction. The program includes both theory and hands-on practice, such as changing pouches and self-catheterization. Researchers will measure c…

This study looks at how clear aligners change after being molded and worn for two weeks. Researchers will compare single-layer and multi-layer aligners in 20 people with mild crowding. They will measure surface roughness, hardness, and thickness at three stages: before molding, a…

This study looks at two ways of placing dental implants in people who have lost all their teeth. One method uses a fully guided surgical guide, the other uses a partially guided approach. The goal is to see which method places the implants more accurately and helps the final teet…

This study compares two methods of picking up attachments for implant-supported dentures: one done digitally before recording jaw relations, and the other done directly in the mouth during denture insertion. Ten participants will receive both types of dentures, and researchers wi…

This study compares three types of dental onlays (a type of filling that covers part of a tooth) for treating cavities. It involves 36 adults who each need at least three onlays. The onlays are made using 3D printing, milling, or indirect resin composite. Researchers will check h…

This study looks at how clear aligners and traditional braces move teeth in 20 adults with mild crowding. Researchers will measure inflammation markers in gum fluid and track tooth movement using 3D scans to understand the differences. The goal is to help dentists choose the best…

This study looks at whether vitamin D levels in the blood affect bone loss around dental implants that support lower dentures. Researchers will measure bone changes and gum health in 40 adults aged 40-60 who already have these implants. The goal is to understand if vitamin D help…
