An in-vitro evaluation of mechanical and esthetic properties of orthodontic sealants.

Objective: To evaluate mechanical and esthetic Properties of two commercially available orthodontic sealants: Opal ® Seal (OS) and L.E.D. Pro Seal (PS). Materials and Methods: Discs of each sealant were prepared to test the following properties: Micro hardness, wear resistance and color stability. Samples were randomly selected after the wear test for SEM imaging to analyze surface morphology. Results: OS was significantly harder than PS ( P P P Conclusion: Both orthodontic sealants are beneficial for protecting enamel. However with better wear properties PS was superior in resisting mechanical stresses. OS was more color stable.
