Fracture resistance of roots obturated with three different materials
Objective The aim of this study was to compare the fracture resistance of roots obturated with different materials. Study design Sixty root canals were instrumented and divided into 4 equal groups (n = 15 each). The root canals in group 1 were filled with AH26 sealer and gutta-percha, in group 2 wit...

Zusammenfassung: | Objective The aim of this study was to compare the fracture resistance of roots obturated with different materials. Study design Sixty root canals were instrumented and divided into 4 equal groups (n = 15 each). The root canals in group 1 were filled with AH26 sealer and gutta-percha, in group 2 with Resilon and Epiphany, and in group 3 with Ketac-Endo Aplicap and gutta-percha. Fifteen root canals had no obturation. The force required to fracture was recorded. The data was analyzed with analysis of variance and Duncan test. Results The mean force of fracture for group 1 was significantly higher than for the other 3 groups ( P < .05). There was significant difference between group 2 and group 3 ( P < .05). Group 2 and group 3 were not significantly different from the control group ( P > .05). Conclusion The use of AH26 + gutta-percha increased the fracture resistance of instrumented root canals compared with Resilon + Epiphany and Ketac-Endo Aplicap + gutta-percha. |
