A core build up is a restoration placed in a severely damaged tooth in order to restore the structural balance, functional efficiency and aesthetic harmony of the dentition (including oro-facial structures). In order to achieve these criteria, certain factors should be kept into consideration such as: it should protect the remaining tooth from fracture, it should have sufficient compressive strength to resist intra-oral forces, sufficient flexural strength to prevent core dislodgement during function, biocompatibility with the surrounding tissues, ease of manipulation, ability to bond to tooth structure, pins and posts, dimensional stability.
To compensate its drawbacks and to enhance its durability, certain materials have been introduced in order to fulfil most of its criteria. Certain materials such as amalgam, resin based core build up materials, glass ionomer cements and others have been introduced.
These resin based core build up materials met most of its demands which is required in order to fulfil its criteria for an ideal core build up materials. Most of the resin based core build-up materials placed in increments in order to cure completely but now a days few of its materials can be placed in bulk such as Bulk Flow materials and some materials releases fluoride such as Fluorocore, Absolute dentin core build up composite, Pulpdent Hardcore.
Therefore the review of this literature could be a helpful for dentists to use these new promising restorative materials with long term clinical outcome.
