This study compared two surgical techniques to repair a torn back part of the knee's cushion (medial meniscus root tear). Forty adults aged 20-50 with this tear were randomly assigned to one of two arthroscopic repair methods. The goal was to see which surgery better restores kne…

This study tested whether a selenium gel can help treat oral lichen planus, a chronic inflammatory condition that causes painful sores in the mouth. Fifty adults with the condition used either selenium gel, a standard steroid cream, or an immunosuppressant cream. The goal was to …

This study looked at 40 children with Hirschsprung disease who had one of two types of surgery to remove the diseased part of the colon and reconnect the healthy part to the anus. The goal was to see which technique led to better bowel function, like the ability to hold in stool …

This study tested a new device called the Leaf Self Expander to widen the upper jaw in 20 children with cleft lip and palate. The goal was to see if it works better than the standard expander. Researchers used 3D scans to measure changes in bone and tooth position. The study is c…

This study looked at 24 people with no teeth in their lower jaw who got dentures held in by two small dental implants. Researchers compared two types of clips (ball-and-socket vs. Equator) to see which one caused less bone loss and better bite force. The goal was to find which at…

This study looked at 80 children with a type of hypospadias (a birth defect where the urine opening is not at the tip of the penis) who had a narrow urethral plate. The researchers compared two different surgical repair methods to see which had fewer complications and better cosm…

This study tested whether a gel made from liquorice could help treat advanced gum disease, comparing it to a diode laser treatment. 27 adults with stage III periodontitis took part. The main goal was to see how well each treatment reduced harmful bacteria in the gums.

This study tested two different attachment systems (Equator and Novaloc) for implant-supported lower dentures in 26 people aged 60-70 with no teeth. The goal was to see which attachment provides better denture retention and improves quality of life. Participants received two impl…

This study tested a special dental device (hybrid rapid maxillary expander) combined with tiny bone perforations (MOPs) to widen the upper jaw in 14 adults aged 17-23 with a narrow jaw and crossbite. The goal was to see if this approach could safely increase jaw width. Results ma…

This study looked at 40 active adults aged 65 and older who had a certain type of broken hip. It compared two surgeries: total hip replacement and a partial hip replacement called bipolar hemiarthroplasty. The goal was to see which one led to better pain relief and function after…

This study looked at whether surgery to fix a blocked nose can improve snoring and sleep apnea in adults. Thirty people with nasal obstruction and sleep apnea had surgery. The main goal was to see if their breathing pauses during sleep (measured by the apnea-hypopnea index) got b…

This study tested two different tools—a special drill and a magnetic hammer—to widen a narrow jawbone so dental implants can be placed. Five adults with thin jawbones but good overall health took part. The main goal was to see how stable the implant was right after placement. The…

This study tested whether a high-speed nasal air flow device (HVNI) works as well as a face mask ventilator (NIV) for COPD patients who have trouble breathing and high carbon dioxide levels. 66 adults took part, and researchers measured changes in blood gases and hospital stay le…

This study tested two different attachment systems for implant-supported dentures in 16 people aged 60-70 with no teeth in the lower jaw. The goal was to see which system led to better gum health, less plaque, and fewer Candida albicans (a fungus that can cause infections). Resea…

This study looked at 100 adults with COPD who needed a breathing tube and a ventilator. It compared two approaches: giving sedation with daily breaks versus giving no sedation at all. The goal was to see which method leads to more days off the ventilator and fewer complications i…

This study looked at 201 women who had repeat C-sections to find the safest time gap between surgeries. Researchers compared groups with intervals from under 12 months to over 48 months, tracking complications like bleeding and injuries. The goal is to help doctors and mothers pl…
