Antibiotic prevention study for high-risk bone and spine surgeries
This Phase 3 study tests whether giving a broad set of preventive antibiotics before certain high-risk orthopedic surgeries lowers the chance of serious wound or bone infection. It mainly targets people who have contaminated wounds, tumor-related surgery, or known high-risk germs on the skin.
ZurichAges 18 years+ - NCT05822271Recruiting
Surgery first plus aligners to improve jaw alignment

Donor bone to close sinus opening after tooth extraction
This trial tests using sterilized donor bone to repair a hole that opens into your sinus when a severely damaged upper back tooth is removed. The goal is to rebuild the bone so a dental implant can be placed safely later.
TantaAges 20 years+ - NCT06712524Recruiting
Comparing surgery types for granulomatous mastitis
This study compares different surgical methods for treating granulomatous mastitis, a rare inflammatory breast condition. It aims to find which approach works best for patients who can safely have surgery.
Wuhan, HubeiAges 18 years+ - NCT04692714Recruiting
Cemented vs cement-free robotic knee replacement surgery
This trial compares two ways surgeons can attach a knee replacement using robotic-assisted surgery: with cement or without cement. It may help improve how well the new knee lasts and how patients recover after a first-time knee replacement.
LyonAges 50–80 - NCT06713044Recruiting
Quran recitation or music for pain after leg surgery

Protein Levels in Gum Disease Before and After Minimally Invasive Surgery
This study measures a natural protein in your gums before and after a minimally invasive surgical treatment for moderate to advanced gum disease. Researchers want to understand how this protein changes with treatment, which may help improve gum disease care in the future.
CairoAges 18 years+ - NCT07595705RecruitingPhase 2
Testing gum pigmentation removal treatments
This study tests treatments to lighten dark spots or patches on your gums for cosmetic reasons. If you have visible brown or black discoloration on your gums and are interested in a minor procedure to improve their appearance, this trial may be for you.

Heart surgery with chest artery grafts: infection and pain study
This study follows patients undergoing bypass surgery where a artery from the chest wall (internal mammary artery) is used to reroute blood around blockages in the heart. Researchers will track infection rates, how well the graft stays open, and pain levels after surgery to understand how well this approach works.
Ottawa, OntarioAges 18 years+ - NCT07597213Recruiting
Hyaluronic acid to help gum disease treatment in smokers

Surgery versus chemotherapy for early-stage small cell esophageal cancer
This study compares how well surgery works compared to chemotherapy and radiation for treating small cell cancer that started in the esophagus and hasn't spread far. Researchers will examine which approach helps patients live longer.
Nanjing, JiangsuAges 18 years+ - NCT04001842Recruiting
Tested new jaw bone repair to support future dental work
