Abstract:In this study, apical and coronal sealing efficicies of root canals was evaluated which were prepared with various root canal instruments and filled with different tapered gutta percha cones using with lateral compaction and single cone techniques by fluid filtration method. In this study, 168 extracted maxillary incisors roots were used. 9 of the teeth were selected as positive and another 9 teeth were selected as negative control groups. 150 teeth were randomly divided into three groups. In group 1, 30 roots were prepared with stainless steel root canal instruments and then were filled with lateral compaction technique by using .02 tapered master cones. In group 2, 60 roots were prepared with nickel titanium ProFile instruments and 30 of the samples were filled with lateral compaction technique by using .02 tapered master cones and 30 of the roots were filled with single cone technique by using .06 tapered gutta percha cones. In group 3, 60 roots were prepared with nickel titanium ProTaper instruments and 30 of the samples were filled with lateral compaction technique by using .02 tapered master cones and 30 of the roots were filled with single cone technique by using .06 tapered gutta percha cones. The apical and coronal leakage of all these samples were evaluated with the fluid filtration model. The results were statistically analyzed with one-way ANOVA. No statistically significant differences were recorded between the groups which were prepared with stainless steel and nickel titanium instruments (p>0.05). The comparative of root canal filling techniques revealed that there was no statistically difference between single cone technique and lateral compaction technique (p>0.05). In conclusion, between all these groups, the groups which were prepared with nickel titanium ProFile and ProTaper instruments and filled with lateral compaction technique showed significantly less coronal leakage than the group which was prepared with stainless steel instruments and filled with lateral compaction technique (p<0.05). There was no statistically significant difference between the apical leakage of the groups (p>0.05).
