    Author(s): Muthanna Ibrahim Nayyef* and Adel Farhan Ibraheem

    Aims: The aim of this study was to evaluate the effect of different marginal cement space thickness and different luting agents on the microleakage of monolithic zirconia crown restorations. Materials and methods: forty-eight human first premolars were prepared to receive full anatomic crowns milled from KATANATM zirconia disc, divided into two main groups (n=24) based on different marginal cement space thickness; Group A- zero μm marginal cement space and Group B- 25 μm marginal cement space. Each group was then subdivided into three subgroups (n=8) based on the luting agent used: (A1, B1) cemented with RelyX Ultimate adhesive cement, (A2, B2) cemented with RelyX U200 self-adhesive cement and (A3, B3) cemented with Riva Luting Plus Resin-modified glass ionomer cement. After cementation and thermocycling (500 cycles), the samples were then emersed in 2% methylene blue for 24h. B.. Read More»
