TI  - Can Increasing the Manufacturer's Recommended Shortest Curing Time of 
      High-intensity Light-emitting Diodes Adequately Cure Sealants?
PG  - E7-13
AB  - PURPOSE: To investigate sealant depth of cure after increasing the curing times 
      of high-intensity light-emitting diode units (LEDs). METHODS: Three sealants 
      (opaque-unfilled, opaque-filled, and clear-filled) were light cured in a 
      covered-slot mold with: (a) three LEDs (VALO, SmartLite, Fusion) for six to 15 
      seconds; and (b) a quartz-tungsten halogen (QTH) light for 40 seconds as a 
      control (N=10). Twenty-four hours after light curing, microhardness was measured 
      at the sealant surface and through the depth at 0.5 mm increments. Results were 
      analyzed via analysis of variance followed by the Student-Newman-Keuls test 
      (significance level 0.05). RESULTS: The opaque-filled and clear-filled sealants 
      cured with VALO for six or nine seconds had hardness values that were 
      statistically equivalent to or better than the QTH to a depth of 1.5 mm. Using 
      Fusion for 10 seconds (exposure limit) did not adequately cure the three sealants 
      beyond one mm. SmartLite at 15 seconds (maximum exposure period without 
      overheating) did not adequately cure the sealants beyond 0.5 mm. CONCLUSIONS: 
      Among the tested high-intensity LEDs, only VALO at double or triple the 
      manufacturers' shortest curing time (six or nine seconds) provided adequate 
      curing of opaque-filled and clear-filled sealants at 1.5 mm depth compared to the 
      40-second QTH light.
