“…In our study, citric acid 42% did not remove the smear layer from the apical third of the canals. These results are in agreement with studies of citric acid at different concentrations that reported differences in smear layer removal between the apical third and the other two thirds of root canals (26,27,31,36,37). Thus, the available evidence indicates that the application of higher volumes of citric acid over 1 minute improves efficacy in removing the smear layer.…”

Introduction: This study compared the efficacy of BioPure MTAD (Dentsply Tulsa, Tulsa, OK), 17% EDTA, and 42% citric acid in endodontic smear layer removal and degree of erosion in the apical third of endodontic canals. Methods: Ninety-six extracted single-rooted human teeth were randomized into four groups (n = 24) and instrumented using System GT nickel-titanium rotary instruments (Dentsply Tulsa, Tulsa, OK). Each canal was irrigated with one of the following solutions: BioPure MTAD, 17% EDTA, 42% citric acid, or 5.25% NaOCl (control). Next, all specimens were irrigated with 5.25% NaOCl. Results: Evaluation by scanning electron microscopy showed no significant differences among test irrigants in removing the smear layer. However, the efficacy of BioPure MTAD and 17% EDTA in removing the smear layer was significantly greater than 5.25% NaOCl (control). The erosive effects of irrigating solutions could not be evaluated. Conclusions: In conclusion, the protocols used in this study were not sufficient to completely remove the smear layer in the apical third of prepared root canals. (J Endod 2009;35:900-903)

“…Moreover, investigations into its use in endodontics have revealed its ability to remove the smear layer (19,20). Another chelating solution, EDTA, is a widely used and effective chelating agent that can dissolve the mineralized part of the smear layer (3,21). For effectively removing of the smear layer from the dentinal walls a combination of EDTA and NaOCl is suggested (22).…”

Objective: The aim of this study was to investigate the effects of two different self-adjusting file (SAF) working times and three different chelating agents on the push-out bond strength of root canal fillings in oval root canals. Materials and Methods: Eighty mandibular premolars were selected and distributed into 8 groups (n=10): 4 min SAF (G1), 4 min SAF + 17% ethylenediaminetetraacetic acid (EDTA) (G2), 4 min SAF + 10% citric acid (CA) (G3), 4 min SAF + 1% peracetic acid (PAA) (G4), 6 min SAF (G5), 6 min SAF + 17% EDTA (G6), 6 min SAF + 10% CA (G7), and 6 min SAF + 1% PAA (G8). The root canals were filled using guttapercha and AH Plus root canal sealer, and the teeth were prepared for the push-out assessments using 1.0 mm thick root slices. Loading was performed with a universal testing machine at a speed of 0.5 mm/min; and then, collected data were analyzed statistically (α=0.05). Results: While the different chelating agents significantly affected the push-out bond strength of the root canal filling (p<0.05), the different SAF working times did not (p>0.05). There were no significant differences among the groups in the apical and middle thirds of the roots (p>0.05). In the coronal thirds, G6 and G8 indicated significantly greater bond strength values than G1 and G5 (p<0.05). Conclusion: According to the results, the 4 and 6 min SAF working times did not affect the bond strength of the root canal filling. PAA and EDTA can be recommended for root canal irrigation after SAF usage.

“…The use of 10% CA as a final irrigation solution yielded very good results in terms of smear layer removal (30). CA has shown slightly better performance than EDTA at similar concentrations, although both solutions are highly effective in removing the smear layer from root canal walls (31). In vitro studies have provided insight into the cytotoxicity of chelators.…”

The goal of endodontic treatment is to remove all the vital and necrotic tissues, microorganisms and microbial byproducts from root canal system. This goal can be achieved through chemical and mechanical debridement of root canals. This article narrates the specifics and requirements of the irrigation solutions. Sodium hypochlorite is proposed as the primary irrigant by virtue of its organic tissue dissolution capacity and broad antimicrobial properties. On the other hand, chelation solutions are recommended as auxiliary solutions to remove the smear layer or to hinder its formation on dentin surface. Thus, it's hoped that sealers and root canal fillers can penetrate to dentin tubules and obturate the canals hermetically. There are new studies on traditional irrigants especially on some irrigants that can replace sodium hypoclorite. This article reviews the new irrigants which can be used in future endodontic practice, and their advantages and limitations. Moreover, actions and interactions of recently used irrigants are adverted.
