Self-adhesive resin cement is highly recommended for cementation of fiber post systems, since it binds chemically with calcium ions in the hydroxyapatite particles without surface pretreatments of dentin. Unfortunately, chelating agents that are used to remove smear layer reduce the calcium ion content of superficial dentin. This study aims to evaluate the effect of remineralization of dentin on the bonding strength of fiber post using the biomimetic remineralizing agent CPP-ACP in vitro. Such a study will provide evidence on the possibility of improving bonding strength by increasing dentin mineral content. At the same time, it should be supported by further clinical studies since it remains in vitro.
21 freshly extracted single rooted teeth will be treated endodontically, prepared for post space, and divided randomly into 3 groups: EDTA+CPP-ACP, EDTA + NaOCl, EDTA alone. Fiber post will be cemented and push out bond strength will be measured for all groups. The expected time of study is 6-8 months.
