This study tests three methods to restore the small triangle of gum between teeth (papilla) that can be lost due to gum disease. The three techniques are: injecting hyaluronic acid (a filler), injecting a special blood-derived material (ALB-PRF) that lasts longer, or a minor surg…

This study tests a custom 3D-printed device that uses small bone screws to widen the upper jaw in 16 young adults aged 18-30. The device is turned once daily for three months. Researchers will use 3D X-rays to measure how much the jaw widens and how teeth shift. The goal is to se…

This study compares three types of tooth-colored onlays (custom-made fillings) for back teeth with deep cavities that extend below the gum line. Researchers will first build up the cavity edge, then place each onlay in 18 adults. They will check the fillings at 2 weeks, 6 months,…

This study tests whether 3D-printed fixed braces (Twin Block) or MARA appliances work better for correcting a common jaw misalignment in preteens. About 60 children with a small lower jaw will be randomly assigned to one of the two treatments or a no-treatment group. The goal is …

This study looks at two types of braces for teenagers aged 12-15 with a specific overbite (Class II malocclusion). One brace is custom-made for each patient, the other is a standard ready-made version. Researchers will measure how long treatment takes, changes in jaw and teeth po…

This study tests whether a stellate ganglion block (an injection near nerves in the neck) given before mastectomy can prevent depression and chronic pain after surgery. The trial will include 140 women with breast cancer scheduled for mastectomy. Researchers will measure depressi…

This study tests whether numbing the nerves in the upper and lower jaw before surgery can reduce pain and the need for rescue painkillers after the procedure. About 60 adults having elective jaw surgery will be randomly assigned to receive either the nerve block or a placebo. The…

This study tests whether a combination of two drugs (mirabegron and solifenacin) works better than the standard medicine (desmopressin) for children who wet the bed. About 120 children will take either the combo or desmopressin daily for 3 months. Researchers will track how many …

This study tests if special pelvic floor exercises can reduce or stop the small amount of urine that leaks after men finish peeing. 120 men aged 18 to 40 will either do targeted pelvic floor exercises or general exercises for 12 weeks. Researchers will measure changes in dribblin…

This study tests whether injecting botulinum toxin (like Botox) into the lip after cleft lip surgery can make the scar smaller and less noticeable. About 32 people with a unilateral cleft lip will take part. Researchers will measure scar width and use a standard scar scale to see…

This study tests three ways of taking dental impressions for 3D-printed lower dentures that snap onto two implants. Sixteen adults with no teeth will try each denture for three months. The goal is to see which method gives the best chewing ability and highest patient satisfaction…

This study tests whether taking two erectile dysfunction drugs together—daily tadalafil plus on-demand sildenafil—works better than sildenafil alone for men who don't get results from standard ED pills. About 500 men with ED for at least 6 months will take the combination or a pl…

This study compares two once-daily pills—tadalafil (5 mg) and solifenacin (5 mg)—to see which better relieves overactive bladder symptoms in women. About 480 women aged 18 to 75 with symptoms for at least 3 months will participate. Over 12 weeks, they will track bladder habits an…

This study looks at whether a simple measurement can predict stridor (noisy, difficult breathing) after a breathing tube is removed in patients who had jaw surgery. Researchers will measure the airway width in 62 adults to see if it helps identify those at risk. The goal is to im…
