A team of researchers with the OHSU School of Dentistry in Portland, Oregon, have created a filling material that's two times more resistant to breakage than standard fillings, according to a study published by the journal Scientific Reports. The new filling uses the additive thiourethane, which is also in protective coatings for cars and decks.
The team also has developed an adhesive that's 30 percent stronger after six months in use than adhesives that are currently used to keep fillings in place. This new adhesive was described in a recent study published in the journal Dental Materials.
Combined, the new adhesive and the composite are designed to make longer-lasting dental restorations.
