What ensues is nearly two hours of the false starts and second-guessing that romances use as sealant.

In sealant programs, dental professionals visit schools to apply a thin, protective coating to the surface of teeth that hardens and safeguards against decay.

Although the defects could be fixed, the report said, some trains required “structural and design modifications” while others needed “sealant, drainage or corrosion corrections.”

The researchers hope this model system can be applied to other types of polymers, including adhesives, sealants and elastomers.
