Root caries

This trial tests whether a one-bottle or a two-bottle HEMA-free dental adhesive works better for filling cavities on the front surfaces of teeth. About 50 adults with early to moderate cavities will receive a filling using one of the two adhesives. Researchers will check how well…

This study compares two dental filling materials for cavities that form near the gum line (cervical lesions). One is a self-hardening composite, the other a flowable composite. Fifty adults will receive one of the two fillings and be checked over 18 months to see which stays in p…

This study compares two treatments for severely damaged lower molars: a tooth-saving surgery called hemisection (removing the damaged root) versus replacing the whole tooth with a dental implant. Researchers will track 28 participants over 12 months to see which option leads to b…

This study compares two treatments for severely damaged upper molars: root amputation (removing only the damaged root and keeping the rest of the tooth) versus replacing the whole tooth with a dental implant. Researchers will track pain, bone healing, and implant stability over 1…

This study tests whether a robot can place dental implants more accurately than a computer-guided navigation system in the front upper jaw. Twenty-four adults needing an implant will be randomly assigned to one of the two methods. The main goal is to see which approach achieves b…

This study tests a new type of tooth filling that sticks to the tooth without needing a separate bonding step. Researchers will compare it to the standard filling method in 75 adults with small to moderate cavities near the gum line. The fillings will be checked over 18 months fo…

This study tests whether different fluoride treatments—like varnishes, solutions, and mousse—can stop root cavities from getting worse in adults over 44. About 136 participants in Switzerland will use these products at home or get them applied by a dentist twice a year. The goal …
