This study compares two common medications for overactive bladder (OAB): solifenacin, which blocks nerve signals in the bladder, and mirabegron, which helps the bladder muscle relax. Researchers want to see if a person's 'anticholinergic burden'—the combined effect of other medic…

This study compares two ways of restoring dental implants: placing a temporary crown right away versus waiting three months. Researchers will track 50 adults over one year to see which approach leads to better implant survival and fewer complications. The goal is to find out if i…

Gum recession exposes tooth roots, causing sensitivity and cosmetic concerns. Standard surgery (CAF + SCTG) covers the root, but healing can be slow. This trial tests whether adding a hyaluronic acid gel (hyaDENT BG®) to the surgery improves root coverage and recovery. Thirty-fou…

This study tests two types of exercise for people with a common knee condition called patellofemoral pain. One group does neuromuscular control exercises (like balance and coordination), the other does muscle strengthening. Researchers will measure pain, function, and movement in…

This pilot study tests a self-guided digital program called MyGENESIS-PATH, designed to help donor-conceived adults cope with stress related to identity, family, and DNA testing. Sixty participants will be randomly assigned to either use the program right away or join a waitlist.…

This study tests whether training healthcare teams in a real operating room (in-situ simulation) is better than training in a simulation center. About 108 professionals from a surgical center will participate in one of two training groups. Researchers will measure teamwork, skill…
