This study compares two methods of closed sinus lifting for people needing dental implants in the upper jaw but lacking enough bone height. One group receives the standard xenograft (bone substitute) alone, while the other gets the xenograft plus a liposomal Apigenin-loaded scaff…

This study compares two types of implant-supported dentures—one made the usual way and one 3D-printed—using two different snap-on attachment systems. Twenty adults with no teeth and good overall health will try both denture designs to see which stays in place better, causes less …

This study tests three materials—amniotic membrane, mineral trioxide aggregate putty, and biodentine—for treating deep cavities in children's permanent molars that are still growing. The goal is to help the tooth root finish developing and avoid root canal or extraction. Seventy-…

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 tests whether adding a substance called i-PRF (made from the patient's own blood) to a standard gum-saving technique (vestibular socket therapy) improves healing and appearance after an immediate dental implant. Twenty-four people with a failing front tooth will receiv…

This study compares two types of dental expanders used to move back molars in people with crowded teeth. One device uses small screws anchored to the bone, while the other relies on the teeth for support. Researchers will use 3D X-rays to measure how much the molars move. The res…

This study tests whether applying dimethyl sulfoxide (DMSO) to aging teeth before placing a filling improves how well the filling bonds and reduces tiny leaks that can cause decay. Thirty adults aged 50-75 with non-cavity tooth lesions will receive either DMSO or chlorhexidine pr…

This study tests whether adding a concentrate from the patient's own blood (injectable platelet rich fibrin, or I-PRF) to a standard bone graft helps repair bone defects caused by advanced gum disease. Twenty adults with stage III periodontitis and deep gum pockets will receive e…

This study compares two materials—enamel matrix derivative and amniotic membrane—to standard blood-clot therapy for regenerating roots of non-vital immature permanent front teeth in children aged 7 to 12. The goal is to see which approach best promotes root growth, closes the ope…

This study tests a surgical technique called retrograde elastic nailing with a pollar K-wire for children aged 3-15 with hard-to-heal wrist fractures. The goal is to see if this method improves bone alignment and reduces complications. Twenty children who failed closed reduction …

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 myofascial release (a type of massage) alone or combined with neck exercises can improve spine alignment, sleep, and mood in people with cervicogenic headache—headaches caused by neck issues. About 100 adults aged 20-55 with this diagnosis will be enro…

This study reviews published research to compare surgical and non-surgical treatments for frozen shoulder (adhesive capsulitis), a painful condition that limits shoulder movement. By analyzing data from previous studies, the researchers hope to identify which approach works best …

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…
