Effects of curing protocol and storage time on the micro-hardness of resin cements used to lute fiber-reinforced resin posts

OBJECTIVES: To determine the micro-hardness profile of two dual cure resin cements (RelyX - U100®, 3M-eSPe and Panavia F 2.0®, Kuraray) used for cementing fiberreinforced resin posts (Fibrekor® - Jeneric Pentron) under three different curing protocols and two water storage times. MATERIAL AND METHODS: Sixty 16mm long bovine incisor roots were endodontically treated and prepared for cementation of the Fibrekor posts. The cements were mixed as instructed, dispensed in the canal, the posts were seated and the curing performed as follows: a) no light activation; b) light-activation immediately ...
