Curing Performance Test

Lay a clean polyester matrix band on white paper and place a clear or white plastic form on the band. The form should be a cylindrical hole 3-6 mm diameter through material 2.0-2.5 mm thick. Pack restorative material into the form, cover with polyester and press flat. Direct the curing light at the top surface (from less than 2 mm) of the sample and cure for the recommended time. Remove the polyester strips and examine the condition of cure. The bottom surface should appear glassy and resist scratching by a sharp explorer, indicating adequate cure. (Consult manufacturer’s instructions for other criteria for correct cure).

If the surface is soft or dull, repeat the test procedure using incrementally longer curing times until adequate cure is attained, and adjust curing time accordingly. If the adjusted time exceeds 200% of normal, verify that the restorative material has not degenerated, or correct curing light problems as directed in the Troubleshooting table.
