Evaluation of apical obturation quality of diferent endodontic materials

The aim of this study was to determine the quality of apical obturation of different endodontic materials, using the colored solutions method. As a material, we used 40 single-rooted teeth, extracted from persons of different ages and sex. We did the root-canals preparation using standard endodontical procedure with KERR reamers and files. After we had prepared root canals, we filled them up, using the lentulo-spirals and Gutta-percha points. For the opturation, we used four different endodontic materials aП26, Ketac Endo, Endomethasone and Sealapex. Under the in vitro conditions, we checked the quality of the apical opturation, using the linear dye leakage method and 2 % methylen blue solution. According to results, we can conclude that endodontic materials AH26 (x=1, 37) and Ketac Endo (x=1,17) showed a significantly lower degree of apical leakage than Endomethasone (x=2. 51) and Sealapex (x=3,25)
