ABSTRACT
Aim: To evaluate and compare the effect of Ceraseal, Guttaflow Bioseal and AH Plus root canal sealers on the fracture resistance of endodontically treated teeth.
Materials and methods: Fourty-five lower premolars were decoronated and divided into one control group and two experimental groups where Group A (n = 15) (Control): canal preparation was done with Protaper Gold system and obturated with AH Plus sealer, Group B (n = 15): canal preparation was done with Protaper Gold system and obturated with Ceraseal sealer and Group C (n = 15): canal preparation was done with Protaper Gold system and obturated with GuttaFlow Bioseal sealer. All root canals were obturated using single cone obturation technique and evaluated radiographically. Roots were then mounted and a universal testing machine was used to assess root fracture resistance.
Results: The highest mean value was recorded in Group (A) AH Plus (651.19±61.97), with a significantly lower value recorded in Group (C) GuttaFlow Bioseal (556.16±36.24), followed by Group (B) Ceraseal (511.71±53.5). One-way ANOVA test revealed a significant difference between groups. Post hoc Bonferroni test revealed that the difference between group B and group C was not statistically significant.
Conclusion: AH Plus improved the fracture resistance of endodontically treated teeth in comparison with Ceraseal and GuttaFlow Bioseal.
