This study tests a new method called the Carrot Technique for rebuilding the jawbone before placing dental implants in the front upper teeth. It uses a small piece of the patient's own bone to widen the ridge, compared to the standard approach using artificial bone and a membrane…

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

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 early study tests a custom-made digital dental device called the Digital Bonded Reverse Twin Block in 21 children aged 8-11 with a mild underbite. The device is designed to gently shift the jaw and teeth into better alignment. Researchers will measure changes in jaw position…

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 compares a custom-made bio-implant (shaped like a natural tooth root) to a standard screw-type implant for supporting partial dentures in people missing back teeth. Eight participants with a specific tooth arrangement received both types of implants. Researchers will m…

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 applying fluoride varnish to teeth can prevent white spot lesions in people undergoing clear aligner treatment. Twenty-five participants aged 16 to 24 with mild crowding will have one side of their mouth treated with fluoride varnish and the other side le…

This study tests whether mirror therapy can help people who have had a stroke regain movement and reduce pain in a weak arm. Participants do arm exercises while watching the reflection of their good arm, which tricks the brain into thinking the weak arm is moving. The trial invol…

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 methods to reduce pain from insulin injections in children aged 6 to 12 with type 1 diabetes. One method uses firm thumb pressure on the injection site for 10 seconds before injecting, and the other uses a small plastic device called a Shotblocker that pre…

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 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 tests whether adding dexmedetomidine to spinal anesthesia can extend pain relief after knee surgery. One hundred adults scheduled for elective knee surgery will receive either the drug or a placebo. Researchers will measure how long it takes before patients need additi…

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 looks at whether a measurement called the stone heterogeneity index (SHI), taken from a CT scan, can predict how well shock wave lithotripsy (SWL) breaks up upper urinary tract stones in children aged 1 to 18. Researchers will follow 286 children for three months after…

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 change after being 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 before and after use to see which material pe…

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 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 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…

This study compares two techniques for placing dental implants in people with no teeth: fully guided (using a surgical guide) and partially guided. Sixteen participants will receive implants in both jaws, and researchers will measure how accurate the implant positions are and how…
