Vertical root fracture is recognized as one of the main reason for tooth extraction. Some successful cases of saving tooth were reported to have been carried out by extracting the fractured tooth atraumatically, bonding the fragments with 4-META MMA TBB rein cement, and then replanting the tooth with a 180° rotation. In those cases, adhesive surface may severely suffer water degradation, however durability of using resin cement on root dentin has not been investigated. Therefore, the aim of this study is to evaluate the micro-tensile bonding strength durability of three MMA-based adhesive resins bonded to human vertical root fracture dentin.
