Dental crown study seeks best cement for Long-Lasting tooth repair

This study looks at whether the type of cement used to attach a zirconia crown to a back tooth affects how well the crown holds up over time. About 110 adults who need a single crown on a back tooth will get either a glass ionomer cement or a resin cement. Researchers will check the crowns yearly for up to 10 years to see which cement leads to fewer problems and better patient satisfaction.
