“…So using solvents seems to complicate rather than facilitate the filling removal (43) . This was agreed with, Kfir et al (6) Das et al (17) Bhagavaldas et al (18) and Dadresanfar et al (19) .…”

The Aim: of this study is to evaluate the efficacy of Reciproc and manual techniques with and without solvent for removing Real-Seal obturating system and Gutta-percha with resin sealer using Stereomicroscope. Methods: Eighty extracted mandibular premolars having single root canal were distributed into two groups stated on the obturation systems (Real-Seal obturating system and Guttapercha with resin sealer) used. Then subdivided into two subgroups according to the method of obturating material removal (Reciproc and manual technique). Further subdivided into two classes by using solvent or not. Roots were separated in bacco-lingual direction into two equal halves then analyzed using Stereomicroscope at the cervical, middle and apical parts. Results: Reciproc system as retreatment instrument give the best result than manual instruments in removing both obturating material used (Real-Seal system and Gutta-Percha) and this was statistically significant. Without using solvent give the best result than using solvent in removing both obturating material used (Real-Seal system and Gutta-Percha) and this was statistically significant. Apical region recorded highest debris mean value followed by middle region while the lowest mean value recorded cervically and this was statistically significant. Conclusion: Reciproc system was more effective than manual instruments in removal of root canal obturating materials for endodontic retreatment.

Introduction:The aim of this study is to compare the effectiveness of reciprocating and continuous rotary nickel-titanium instruments during retreatment performed through two different access outlines.Methodology:A total of 48 freshly extracted mandibular first and second premolars with single root and canal were selected. Initial root canal treatment was completed through a contracted endodontic cavity (CEC) design. Canals were instrumented with F2 ProTaper instrument, obturated with warm lateral condensation of gutta-percha with AH Plus sealer, and allowed to set for 30 days at 37°C and 100% humidity. For retreatment, specimens were divided into two groups (n = 24) on the basis of access outline, CEC or traditional endodontic cavity. Retreatment was initiated using ProTaper Retreatment instruments (D1–D3). Specimens were further divided (n = 12) and reinstrumented up to Neoniti 25/0.08 or WaveOne 25/0.08. Irrigation was performed using 3% sodium hypochlorite and 17% ethylene diamine tetraacetic acid. Retreatment time was recorded. Teeth were sectioned and photographed, and the percentage of remaining obturation material was measured.Results:Data were collected, and statistical analysis was performed using one-way analysis of variance and Tukey honestly significant difference multiple post hoc procedures (P < 0.05).Conclusion:None of the systems completely removed the root filling material from root canals. However, ProTaper/Neoniti instruments removed more GP when compared to Protaper/WaveOne instruments with both the access outlines. Both the instruments with traditional access outline required less time for removal of obturating material when compared to CEC.

“…The use of solvent in the present study may have resulted in GP and sealer adherence to the canal walls. The reason for residual GP and sealer could be attributed to the solvent ability to soften GP and modify its structure to increase the viscosity and adhesion of the obturation material, which makes it more difficult to remove especially in oval canals (35). Few studies assessed the retreatment outcome when bioceramic sealers have been used in obturation.…”
