This study compares two balloon treatments used after placing a stent in long blockages (over 10 cm) in the leg arteries of people with peripheral artery disease. One balloon is coated with a drug to help keep the artery open, while the other is a standard balloon. The goal is to…

This study tests three cleaning aids—superfloss, interdental brushes, and a water flosser—in people with full-arch implant-supported fixed dental prostheses. Each participant will use each method for three months to see which removes the most plaque. The goal is to find the best …

This study tests a new treatment for people with high-risk head and neck cancer who cannot receive the standard chemotherapy drug cisplatin. After surgery, patients receive radiation therapy combined with a targeted drug (nimotuzumab), followed by an immunotherapy drug (benmelsto…

This study compares two ways to treat early gum disease (gingivitis and mild periodontitis). One group uses a smart electric toothbrush with an app, while the other adds professional dental cleaning. The goal is to see if the toothbrush alone works just as well. About 92 adults w…

This study aims to see if simpler, less invasive methods like taking mouth photos, answering a questionnaire, or testing saliva can accurately detect gum disease (gingivitis and periodontitis). Researchers will compare these methods to the standard full-mouth dental exam in 2,000…

This study aims to develop and validate an artificial intelligence system that uses color analysis of digital dental scans to objectively diagnose gum redness (erythema) around dental implants. Currently, diagnosing this sign of inflammation is subjective and varies between denti…

This study tests whether taking taurine granules before daily radiation can reduce mouth sores and skin burns in 160 oral cancer patients. Half receive taurine, half a placebo, and researchers track severity and safety. The goal is to ease common, painful side effects of radiothe…

This study aims to discover biological markers that can predict which people with mild gum inflammation will develop serious gum disease. Researchers will analyze saliva, tissue, and bacteria samples from 228 adults aged 18-40 with gingivitis or early-stage periodontitis. The goa…
