Abstract：AIM: The purpose of this study is to compa ir the different materials used in root canal therapy. Measuring and co mparing their effects on the anti-fracture strength of human teeth to the effec t of conventional method provide experimental evidence for it s clinical use. METHODS: There were two hundred twenty-fou r intact human premola rs and molars extracted within three months being randomly divided into seven gr oups. Then MOD cavity and root canal were prepared and filled in five groups. In tact and MOD cavity and endodontic prepared teeth with no restoration were used as control. The RM electro-mechanical testing machine is used to perform the tes ts. RESULT: The anti-fracture strength of the teeth treate d by new technique was significantly higher than that of the control. CONCLUSIONS: It is an effective way to increase anti-fracture strength. In which the root canals were obturated b y AH Plus with metal cone point, and coronals filled with Aqua Cem as an adhesiv e liner by the metals inlay restoration.
