Abstract
Endodontically treated teeth usually suffer from higher risk of fracture so they usually treated using post and core systems. Two types of prefabricated posts were used one was a post of titanium alloy and the other was a ceramic post. They luted using a resin cement after being treated with cojet system and CO2 laser. Retention and fracture resistance were examined using a universal testing machine.
