Research summary
Endodontically treated teeth are more susceptible to fracture than vital teeth because of the amount of reduction of tooth structure. In many instances, a post and core restoration is required to compensate for reduced tooth structure. With the availability of adhesive techniques, fibre reinforced composite (FRC) posts are frequently used to restore severely broken down endodontically treated teeth due to their elasticity which is close to that of dentine that reduce the stress transmitted to the tooth structure and therefore reducing the incidence of root fracture. The main limitation of current commercial post systems are loss of strength due to cyclic loading and the difficulty of removing when root canal re-treatment is required. In our study a new fibre composite tailored to function as a post material will be developed by incorporation of hydroxyapatite and nanofibre . This new material will be at the same time strong (resistance flexural stresses) and easily removable. This project will investigate the performance of newly fabricated posts along with modified self-adhesive resin cement as a luting agent. This project will consist of four work packages:
1.Investigation of the fracture resistance under static and fatigue loading of endodontically treated teeth restored with the fabricated post in comparison with other commercial post.
2.Development and assessment of self-adhesive resin cement as a luting agent for the fabricated post.
3.Assessment of permeability of the new post system by measuring dye infiltration.
4.Evaluation of the removal efficacy of the new posts in comparison with commercial post system.REC name
