IORIO, Lecy Schwantes et al. Removal manual or mechanized of filling material Root Canal: Gutta-percha x Real Seal. Rev. Assoc. Paul. Cir. Dent. [online]. 2012, vol.66, n.4, pp. 292-297. ISSN 0004-5276.

This study compared the remaining filling material and working time removing gutta-percha/AH Plus and Real Seal/Epiphany from root filled. The root fillings were removed using two methods: ProTaper® Retreatment and Hedströem files. Sixty extrated single-rooted teeth were divided into four groups of 15 specimens each. The canals were obturated using Real Seal and Epiphany sealer and gutta-percha and AH Plus. Radiographs were taken before and after the retreatment and the amount of remaining material was quantified using the software Image Tool. No significant differences were found for retreatment between gutta-percha filled groups. Retreatment of specimens filled with Real Seal using ProTaper® Retreatment files showed less remaining filling material. The Real Seal/Epiphany removal using Hedströem files was faster than the other groups. Clinical relevance: Understanding the new filling material behavior (Real Seal) in retreatment cases using manual removal or rotary instruments.
