X-ray Microscope Designed To Study Jet Engine Components Now Probes Tooth Dentin
... 50 percent of dentin is mineral -- bonds are more difficult
to form. Byusing the powerful microscopes to observe the bonding process, the UCSFresearchers now can offer a better explanation of the reasons bonds succeed andfail. When dentists prepare a tooth for bonding a filling, they use an acid todemi...
