Sealing ability of cements on zirconia restorations

The ability of a material to seal can be explained as its capacity to avoid the penetration of fluids, molecules, ions, and bacteria between a restoration and tooth material. The lifetime of a restoration can be affected by sealing ability. The evaluation of sealing ability in dental material is measured using micropercolation tests. Generally these are in  vitro tests and use various standardized methods for dental preparations and thermocycling to age the obturation and assembling material between tooth and restoration.
