Abstract
Abstract

Objective: investigation of the microshear bond strength between lithium disilicate with preheated viscous composite, flowable composite and resin cement by comparison of their microshear bond strength.

Material and method: forty five samples were prepared and divided into three groups; preheated viscous composite group, flowable composite group and resin cement group. Materials were injected into custom made plastic transparent molds (2 mm height, 2 mm diameter) on surface of lithium disilicate discs that were previously surface treated with ceramic etchant (hydrofluoric acid 4.5%) and ceramic primer (silane coupling agent). Then, Microshear bond strength test was performed to samples by universal testing machine. Results were tabulated and statistically analyzed for each group.
Results: highest microshear bond strength was recorded for preheated viscous composite followed by flowable composite and resin cement.
Conclusions: preheated viscous composite is an excellent material in cementation of lithium disilicate ceramic restorations.
Keywords: Lithium disilicate; Preheated composite; microshear bond strength.
