New Resin Tested to Stop Dental Decay Before Drilling and Filling

Researchers from the Case Western Reserve University School of Dental Medicine are testing a new noninvasive resin polymer material to infiltrate tooth enamel to seal and stop the spread of dental decay.

The noninvasive dental resin could be a new product in the dentist's medicine cabinet — along with fluoride varnish, dental sealants and the tooth brushes and dental floss for oral hygiene — to ward off and stop tooth decay from spreading and destroying the tooth's surface.

Dental researchers Jin-Ho Phark and Silas Duarte are interested in a resin material produced by DMG (Dental-Material Gesellschaft), a German dental products company. They discussed the new product in the article, "Caries Infiltration with Resins: A Novel Treatment Option for Interproximal Caries," in the journal Compendium of Continuing Education in Dentistry.

The researchers will clinically test the resin product on 40 adolescences who have completed their orthodontic treatments and have just had their fixed braces removed within the past three months.

What interests the researcher is how much this product can reverse white spots, or the beginning lesions associated with dental decay resulting from hard to clean areas. They also want to see if the resin holds up over the two years the subjects would be in the study.

Narrow spacing between teeth is another problem area to keep clean. The resin polymer may help to keep the teeth healthy.

If current noninvasive methods, like flossing and fluoridation, do not work, then dentists must use invasive procedures and go in and remove the decayed areas by drilling. Drilling weakens the teeth and over time fillings need to be replaced every 7 to 10 years, which requires more enamel removal and further weakening of the teeth.

"The idea is to develop a product that at a minimum delays decay or prevents it," Phark said.

He added, "We also want to find a product that is an intermediary treatment between noninvasive and invasive treatments."
