| چکیده انگلیسی مقاله |
In order to evaluate quality of apex filling materials in endodontic surgeries, studies on extracted teeth were conducted. The teeth were selected and after crown dissection, root canal therapy was done by gutta-percha and simple technique. Afterwards, for each tooth 3mm of root apex was cutted and then the samples were divded into 5 groups of 15 samples.two groups of 3 samples were regarded as control groups. Then, a 3mm cavity was made in apex and were filled by amalgam ( vivdentTM or Sina TM), cavit and coltosol in groups number 2 to 5. The gutta-percha was condensed by a round end tool. The samples were placed in Methylen blue for 48 hours and then by scrubbing lateral walls of the teeth, the penetration of color into root canal space was evaluated by steromicroscope. The obtained results showed that Coltosol was acted better and resulted in more significant changes compared to Amalgam vividentTM, SinaTM , Cavit and Gutta-percha.(P≤0.001) |
