Evaluation of a new glass ionomer cement "visible light cured" as a core buildup under a cast restoration

Proper restoration of endodontically treated teeth is a frequent challenge to many clinicians. The majority of restorations are using various types of vertical support that can be placed in teeth, these include different prefabricated post systems as well as cast posts and cores. Less emphasis, unfortunately, has been placed on the materials utilized for final build up. Unless the tooth being treated undergoes minimal loss of tooth structure some from of augmentation will be necessary to increase the tooth strength and provide adequate support and retention for the final cast restoration. It is generally accepted that the ideal methods of corono-radicular buildup for nonvital teeth is a properly fabricated cast post and core.
