New Self Curing Root Canal Filling Material : Gutta flow 2

Aim: To evaluate the apical microleakage with Gutta Flow 2 as an obturating material with or without use of master gutta percha cone as compared to lateral compaction with gutta percha and zinc oxide eugenol sealer. Methods: A total of thirty extracted human mandibular molars were decoronated, sectioned and instrumented with r otary protapers size F1. Teeth were randomly divided into three experimental groups of 10 each labelled as Group G1 (lateral compaction), G2 (guttaflow 2 with master cone), and G3 (guttaflow 2 without master cone). All the teeth were given two coats of nail varnish leav ing 2 mm at the apex. Teeth were immersed in India ink for 48 hrs, demineralized and cleared with methyl salicylate using Robertson’s technique. The apical dye penetration was examined using a stereomicroscope. Results: The mean dye penetration was recorded to be maximum for guttaflow 2 without master cone i.e. 0.69 mm whereas the mean dye penetration value for all canals obturated with guttaflow 2 with master cone was found to be minimum i.e. 0.35 mm w hich was comparable to that of lateral compaction technique i.e. 0.36. On statistical anal ysis, no statistical significant differences were revealed in terms of sealing ability of guttaflow 2 with master cone and lateral compaction whereas it was statistical significant between gutt aflow 2 without master cone and guttaflow 2 with master cone, and guttaflow 2 without master co ne and lateral compaction. Conclusion: The apical sealing ability of Guttaflow 2 with mast er cone was comparable to the gold standard of lateral compaction.
