Online published on 8 October, 2014. Abstract Aim To analyse ex vivo the integrity of the apical seal of Resilon and Gutta flow2 root fillings following immediate post space preparation or after 1 week when leaving either 5 mm or 3 mm of remaining filling material. Methodology Fourty freshly extracted mandibular premolar teethwith single, straight root canals were used. Teeth were autoclaved and cleaned of debris and soft tissue. After decoronation at 16 mm length, the root canals were instrumented using the K3 rotary system to apical file size 45, 0.04 taper with intermittent irrigation using 1% sodium hypochlorite. Then teeth were divided in to two experimental groups. Group one consist of resilon with four subgroups contains 10 teeth each. Group two consist of guttaflow 2 with four subgroups contains 10 teeth each. Microleakage was evaluated using a fluid transport device. The results were analysed statistically using one-way anova. Results Gutta flow2 has shown higher microleakage when compared to Resilon group. However the difference is not significant. Conclusion Immediate post space preparation was associated with less microleakage than delayed preparation when both 5 mm and 3 mm of apical filling remained. Leaving 5 mm of Resilon provided a significantly better seal compared to leaving 3 mm of material. Top Keywords Microleakage, Post Space Preparation, Resilon, Guttaflow2. Top |
