AB  - OBJECTIVE: To determine whether recommended short curing times of three 
      high-power light emitting diode (LED) curing lights are sufficient to polymerize 
      sealant materials. METHODS: Opaque-unfilled sealant (Delton LC Opaque), 
      opaque-filled sealant (UltraSeal XT plus), and clear-filled sealant (FluroShield) 
      were light cured in a covered slot-mold using the manufacturers' shortest 
      recommended curing times with three high-power LED lights (3-s VALO, 5-s Fusion, 
      10-s Smartlite). A 40-s cure with a quartz-tungsten halogen (QTH) light was used 
      as control. Vickers hardness was measured 24 h after curing at the sealant 
      surface and through the depth (0.5 mm increments) (N = 10). Results were analyzed 
      with two-way anova (pair-wise multiple comparisons, significance level 0.05). 
      RESULTS: The high-power LEDs did not cure the sealants as deep as the QTH. Delton 
      LC Opaque showed the least depth of cure as hardness values beyond a depth of 0.5 
      mm were not measurable regardless of the curing light. Even for UltraSeal XT 
      plus, when surface hardness was about the same with all lights, hardness 
      decreased more rapidly with depth for the LEDs. FluroShield showed the slowest 
      decline in hardness through the depth for all lights. CONCLUSIONS: Manufacturers' 
      recommendations for shortest possible curing time with high-power LEDs were not 
      sufficient for adequate polymerization of the tested sealants.
