This study tests whether graphene oxide can successfully treat decayed baby teeth that need pulp therapy. 126 children will be split into groups receiving graphene oxide, standard materials like MTA or zinc oxide, or a lesion sterilization technique. The goal is to see which appr…

This study will compare four different tooth-filling materials used to repair cavities in children's back baby teeth. About 92 kids aged 4 to 8 will receive one of the four fillings, and researchers will check how well each holds up over time and if the child feels any pain after…

This study will compare two fixed dental appliances—the Quad Helix and Rapid Maxillary Expanders—for treating posterior crossbite in 20 Egyptian children aged 9-12. The goal is to see which device widens the upper jaw more effectively and causes less discomfort. Results could hel…

This study tests whether a standard set of emergency steps—like quick blood tests, fluids, and antibiotics—can improve survival for adults with sepsis or septic shock. About 120 patients will be compared: some treated before the new protocol and some after. The goal is to get lif…

This study tests whether natural substances like grape seed extract and glycyrrhizin can replace antibiotics in a procedure to revive dead permanent teeth in children aged 7-13. The goal is to restore blood flow and promote root growth while reducing pain and infection. The trial…

This study tests a new surgery for people whose shoulders keep dislocating. The surgeon uses a piece of the patient's own tendon to build up the shallow part of the shoulder socket. The goal is to make the joint more stable and prevent future dislocations. The study will include …

This study looks at three different materials used to treat deep cavities in children's baby molars. It involves 66 kids aged 4-8 who need a pulpotomy, a procedure that removes infected nerve tissue. The goal is to see which material—hyaluronic acid, TheraCal, or MTA—works best o…

This study checks if an artificial intelligence (AI) system can analyze dental X-rays as accurately as the standard manual method. About 55 people with crooked teeth or jaw issues will have their X-rays read by both AI and a human expert. The goal is to see if AI can be a reliabl…

This study compares two ways of giving spinal anesthesia for planned C-sections: the standard single injection versus a sequential (two-part) injection. The goal is to see if the sequential method reduces the chance of a sudden drop in blood pressure, a common and risky side effe…

This study looks at whether adding a daily physical activity program to structured exercises can improve disability, anxiety, depression, and sleep in elderly people with chronic low back pain. One hundred participants aged 60 and older will be split into three groups: exercise p…

This study looks at whether adding dexamethasone, dexmedetomidine, or both to a standard numbing injection can prevent the intense pain that often happens when the numbness wears off after arm surgery. About 75 adults having upper limb surgery will be randomly assigned to one of …

This study will test whether combining Pilates with resistance training can reduce pain, disability, and sleep problems in people with chronic low back pain. 110 participants will be split into three groups: one doing both Pilates and resistance training, one doing Pilates alone,…

This study compares two types of ultrasound-guided nerve blocks to control pain after open inguinal hernia repair. 66 adults will receive either a lateral quadratus lumborum block or a combined ilio-inguinal/ilio-hypogastric/genitofemoral block. The goal is to see which method re…

This study looks at whether teaching people with long-term neck pain how to sleep better, along with doing special neck exercises, can improve their sleep and reduce pain and disability. About 120 adults aged 20-55 with poor sleep and neck pain for over 3 months will take part. T…

This study looks at whether injecting a small amount of saline or numbing medicine through the epidural needle before placing the catheter can make the procedure more successful on the first try. It involves 216 women in active labour who request pain relief. The goal is to reduc…

This study looks at whether adding pain neuroscience education (teaching people how pain works) to standard back exercises can improve disability and reduce fear of movement in adults with chronic low back pain. About 40 participants in the Gaza Strip will be split into two group…

This study tests three different doses of a drug called dexmedetomidine, given with spinal anesthesia, to see if it can prevent shivering after surgery. 120 adults having kidney stone removal will be randomly assigned to receive one of the three doses or a placebo. The goal is to…

This study looks at whether a quick, painless ultrasound of the eye can predict a common complication called post-dural puncture headache (PDPH) after spinal anesthesia for C-sections. Researchers will measure the optic nerve sheath diameter before and after the spinal block in 1…

This study looks at how a small surgical procedure called corticision affects the body's response when pushing lower front teeth inward during orthodontic treatment. Researchers will measure certain chemicals in the gum fluid and track how much the teeth move. The study involves …

This study tests whether applying a Vitamin D gel (calcitriol) to one side of the upper jaw can speed up the movement of a canine tooth during orthodontic treatment. Twenty-two people aged 13 to 35 who need premolar extractions will participate. The gel is applied only on one sid…
