Abstract : Sealer placement techniques have not been explained in teeth with curved canals prepared with Lightspeed instruments. Three traditional methods of placing sealer were studied, using 45 extracted human single-rooted teeth, divided into 3 groups of 15 Root canal preparations were made with Lightspeed nickel titanium engine-driven instruments AH26 sealer was applied with either K-file, lentulo spiral, or master gutta-percha cone. Radiographs were taken after sealer placement and analyzed for amount of canal sealer fill. The teeth were then obturated with laterally condensed gutta-percha, chemically cleared, photographed, and analyzed for total canal wall sealer coverage. The results showed a statistically significant difference in canal sealer fill among the 3 groups before obturation, but there was no statistical difference in canal wall coverage among the 3 groups after obturation. None of the examined methods exceeded an average of 62.5% all coverage of sealer after obturation. This suggests that complete wall coverage after obturation may not be possible.
