| Abstract | ||
| The sealing ability of root canal filling materials is crucial to the goal of preventing reinfection via microleakage of microorganisms and their by-products. Thirty palatal canals of 12mm length from extracted upper first molars were selected then instrumented and divided into 3 groups. Group I was obturated with lateral compaction technique, group II was obturated with warm vertical compaction technique and group III was obturated with Gutta-Flow system. Except for the apical 2 mm, all other segments of roots for the 3 groups received two layers of nail varnish and immersed in a methylene blue 2% and stored at 37Cº for 30 days. Under stereomicroscope liner dye leakage was measured. No statistical difference was found between lateral compaction, warm vertical compaction and Gutta-Flow sealing ability. | ||
