ABSTRACT
Introduction and objective:
GuttaFlow2 is a further development of the silicone sealer GuttaFlow, exhibiting a stiffer consistency. This is intended to overcome possible problems regarding retention of the apical part of the root canal filling when preparing for a fiber post. GuttaFlow2 is delivered within a capsule, like GuttaFlow, or within an automix syringe. This study compared apical dye leakage of GuttaFlow2 in comparison to GuttaFlow and AH Plus. The null hypothesis tested was that different sealers exhibited similar microleakage. Material andmethods:
Seventy extracted human lower premolars with fully mature apices were root canal prepared to 45/.04 and divided into seven groups group 1 AH Plus sealer, group 2 "normal" setting GuttaFlow, group 3 "fast" setting GuttaFlow, group 4 GuttaFlow2 within a capsule, group 5 GuttaFlow2 within an automix syringe, group 6 positive control, group 7 negative control (n = 10 each). Root canals were filled with sealer (except group 7) and a master gutta-percha cone size 40/.04 using the non-compaction technique. A dye penetration test was carried out by centrifugation for 3 min at 30 G within 5 % methylene blue dye. Linear dye penetration was recorded. Statistical evaluation was carried out with IBM SPSS 19.0 (α = 0.05).Results:
The positive control was significantly different from all other groups (ANOVA, p < 0.001; Student-Newman-Keuls post-hoc test p < 0.05). When the control groups were disregarded, no significant differences were apparent. Groups 1 to 5 showed low leakage values when compared with results of earlier studies using a similar methodology.Conclusion:
All sealers tested exhibited low dye leakage values.
