ABSTRACT:
When a hand-held visible-light curing unit is used in air to cure dental restorative material, a thin layer of soft, uncured surface material ordinarily remains and is removed by grinding. In the invention, the surface of the restorative material is fully cured by the simple expedient of using a hand-held light curing unit whose lightguide has a hollow tube having at least one orifice that is substantially colinear with the lightguide. An inert gas such as nitrogen is gently blown through the orifice and across the surface of the restorative material while the material is being cured by light from the light curing unit.
