Özet:

It is known that endodontically treated teeth are more fragile than vital teeth. Loss of each substance in the tooth due to canal treatment and opened cavities increases the brittleness of the crown of the tooth. Incomplete apex teeth, advanced caries and overdosed canals cause restorative problems for dentists. The success of endodontically treated teeth depends on the structural, aesthetic and prosthetic success of the restoration and the clinical durability of the supporting tissues. Today, post-core systems are widely used in highly coronally damaged teeth. Starting to use materials that are attached to dental tissue as adhesives made it possible to increase the resistance of the remaining tooth tissues. In the teeth whose root canal wall is thinned, it is possible to strengthen the teeth structurally and dimensionally against breaking by supporting the channels with a suitable material. With the use of composite resins, the restoration of large canals with thin walls has become possible. By the use of light-permeable plastic posts, it is possible to strengthen the thin-walled teeth by polymerizing the composite material in the root.
