ABSTRACT
When a traditional method is used to repair residual dental root with horn-shaped orifice, this kind of dental root often has to be extracted since the success rate in clinic is very low. The main reason is that the stress often concentrates on the neck and root apex, therefore the wall at the orifice is too thin to bear this kind of pressure. A new repairing method is proposed trying to preserve the residual dental root with horn-shaped orifice. Then compare the anti-fracture ability of this kind of tooth with that of no repairing. The results show that it is very effective to prevent the fracture of residual dental root repaired by chemical hard synthetic resin followed by making the post and core. However, there is no obvious difference between non-repaired and residual dental root groups repaired by traditional glass ionic adhesives. The results also provide the great possibility to preserve the residual dental root with horn-shaped orifice in clinic.
