Nanodiamonds might prevent tooth loss after root canals

Nanodiamonds may help patients that have had the dreaded root canal. Dental researchers have developed a nanodiamond-reinforced version of gutta percha, the compound that is used to fill void spaces in dental root canals to prevent infection that can lead to tooth loss. Tested in patient-extracted teeth, the nanodiamond-embedded polymer was substantially stronger than conventional gutta percha. In addition, the scientists tested gutta percha with nanodiamonds that had been loaded with antibiotic...
