Pro Seal is the first chemical or light cure sealant that will completely set without an oxygen inhibited layer. This creates a smooth, hard surface that prevents leakage, protects the enamel and makes paste cleanup easier. Pro Seal can be used under any light cure, chemical cure or dual cure paste system. Pro Seal LED has the same great properties as the original Pro Seal, but can be cured with any LED or Halogen light. Now every office can offer their poor hygiene patients long term enamel protection.
