Using DMSO to strengthen fillings for worn tooth notches
This study tests a technique that uses a chemical called DMSO (dimethyl sulfoxide) to help dental fillings stick better to worn or eroded notches near the gum line on the outer surface of premolars. If you have two similar notches like these, this treatment might make your fillings last longer and feel more comfortable.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have two similar shallow notches or cavities on the outer surface of your premolars (the teeth just behind your canines).
- The notches should be small to moderate in size (score 1–3 on a standard tooth wear scale).
- Your bite should be stable, and your teeth should be in normal contact.
- You cannot have notches on the inside (tongue-side) surface of your teeth.
- You must be generally healthy (no major medical conditions) and not have significant gum disease.
- You cannot have a habit of grinding or clenching your teeth, and your back teeth should not show visible wear facets.

This study tests two types of tooth-colored fillings and a special glue for repairing worn spots on the sides of teeth near the gumline. It aims to see which material works best and lasts longest.
This study tests whether adding an extra protective seal over a dental filling helps it last longer. If you have a cavity on the side of a back tooth, you may get a free filling and be monitored for two years.
This trial tests a new tooth-colored filling material for deep cavities that can be placed without removing healthy tooth structure. It may help preserve more of your natural tooth and reduce sensitivity.
This study is testing a special flowable filling material for deep cavities that extend below the gum line in back teeth. The goal is to see if this material reduces the chance of cavities coming back compared to standard treatment.
This trial tests a new way to fill deep cavities in back teeth. They use a natural grape seed extract to strengthen the tooth before placing the filling, which might help the filling last longer and protect the tooth.
This study tests two types of dental fillings for deep cavities to see which one helps the tooth form a protective layer over the nerve. It aims to find a better way to treat cavities that are close to the nerve, potentially avoiding more invasive procedures.
