This study tests whether a vitamin D-based gel (calcipotriol) or a light-activated treatment (photodynamic therapy) can shrink or eliminate oral leukoplakia, a precancerous condition. Thirty adults with mild to moderate dysplasia will receive one of the two treatments for four we…

This trial tests two minimally invasive laser techniques for crown lengthening in adults with a gummy smile caused by altered passive eruption. One method uses a flapless laser approach, the other creates a small tunnel under the gum. Both aim to reduce pain and swelling compared…

This study tests whether custom-made 3D titanium plates are better than standard two-plate systems for fixing a specific type of jaw fracture. Eighteen adults with a broken jaw angle (non-infected, within two weeks of injury) will receive one of the two treatments. The main goal …

This study tests whether custom-made surgical guides can help surgeons safely and accurately treat children with a stiff or fused jaw joint (TMJ ankylosis). The approach uses a special saw to cut the bone precisely. Eight children under 15 are taking part, and the study checks ho…

This study tests whether very short, AI-made videos (under 2 minutes) can help 180 older adults with sarcopenia (muscle loss) follow diet and exercise advice and reduce depression. Participants watch these nano-learning videos at home. The goal is to see if this simple approach i…

This study tests whether garlic tablets can prevent infections that patients often get while in the intensive care unit (ICU). Researchers will give garlic tablets to some ICU patients and compare them to others who do not receive the tablets. The goal is to see if garlic lowers …

This study looks at whether involving pregnant women in decisions about their planned C-section can lower pain and improve their experience during the surgery. About 80 women scheduled for an elective C-section under spinal anesthesia will take part. Half will receive a shared de…

This study tests whether warming the saline used during laparoscopic gallbladder surgery or adding a numbing medicine can lessen shoulder pain afterward. About 216 adults having planned gallbladder removal will take part. The goal is to find a simple way to improve comfort and sp…

This study tests whether adding N-acetylcysteine (NAC) to standard root canal treatment can reduce pain and improve healing in people with infected, dead teeth. Forty adults with mature teeth and signs of infection around the root tip will receive either NAC or standard medicatio…

This study tests a computer-guided needle technique combined with a platelet-rich plasma (PRP) injection for people with a painful jaw joint condition called temporomandibular disorder (TMD). The goal is to see if the computer-guided method improves jaw function and reduces pain …

This study compares two ways to manage pain during cataract surgery: numbing eye drops (topical anesthesia) versus general anesthesia (being fully asleep). Researchers will follow 50 adults for up to six weeks after surgery, measuring pain, complications, and satisfaction. The go…

This study compares two tools, piezotome and periotome, used for gentle tooth extraction before placing a dental implant right away in the front upper teeth. The goal is to see which tool better preserves bone and gum tissue, leading to improved healing and appearance. Thirty adu…

This study is testing whether allowing husbands to be present during planned C-sections affects how smoothly the anesthesia goes, how safe the procedure is, and how satisfied mothers feel. One hundred women having planned C-sections under spinal anesthesia will be randomly assign…
