omparison Between Gutta-Percha and Resilon Removal sing Two Different Techniques in Endodontic etreatment

d f n w u t 3 E w M c a s c g bstract his study compared the remaining filling material and orking time when removing gutta-percha/AH 26 and esilon/Epiphany from root filled extracted teeth. The oot fillings were removed using chloroform and two ifferent rotary systems (K3 and Liberator files). The mount of residual filling material on the canal walls as imaged and measured using image analyzer softare. The group filled with Resilon/Epiphany and rereated with K3 files demonstrated the least residual illing material on the walls (p 0.05). There was no tatistically significant difference between the guttaercha/AH26 and Resilon/Epiphany groups when the iberator files were used (p 0.05). In the groups filled ith Resilon/Epiphany, the filling was removed faster han groups filled with gutta-percha/AH 26 (p 0.05). 3 rotary system was faster than Liberator to remove oth gutta-percha and Resilon (p 0.05). Resilon/ piphany was effectively removed with K3 or Liberator otary files. (J Endod 2006;32:362–364)
