“…However, despite being efficient in removing the smear layer, EDTA has an erosive effect on dentin (7) and attacks the periapical tissues (11) in addition to being considered an environmental pollutant (4). To deal with organic structures, previous studies have sought for weaker and more biocompatible acids than EDTA (5,12).…”

Complete debridement with smear layer removal are essential measures for achieving a successful outcome of root canal treatment. The aim of this study was to evaluate the effects of chitosan at different concentrations on the removal of the smear layer and on dentin structure after 3 and 5 min of application. Twelve recently extracted maxillary canine teeth were instrumented using the crown-down technique and irrigated with 1% sodium hypochlorite. The specimens were distributed according to the time and concentration of the final irrigating solution: G1: 0.1% chitosan for 3 min; G2: 0.2% chitosan for 3 min; G3: 0.37% chitosan for 3 min; G4: 0.1% chitosan for 5 min; G5: 0.2% chitosan for 5 min; G6: 0.37% chitosan for 5 min. All samples were prepared for SEM analysis. G1 exhibited removal of the smear layer, but not the smear plugs. G2 showed visible and open tubules with slight erosion of the peritubular dentin. Cleaning in G3 was similar to that in G2, however, the erosive effect was greater. There was expansion of the diameter of the tubules in G4; and in G5 and G6, there was severe erosion with deterioration of dentin surface. In conclusion, 0.2% chitosan for 3 min appeared to be efficient for removing the smear layer, causing little erosion of dentin.

“…In the literature, there are some studies that compare the smear layer removal effectiveness of EDTA and CA; however, those findings are contradictory. Certain studies reported that 10% CA is more effective than EDTA (24,25); in contrast, some studies found no significant difference between them (23,26).…”

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.

A eficácia da solução de EDTA na remoção de smear layer e sua relação com o tempo de uso: uma revisão integrativa IntroduçãoO sucesso do tratamento endodôntico está intimamente relacionado à qualidade da limpeza e desinfecção do sistema de canais radiculares (SCR), obtido por meio da eliminação ou pelo menos redução do conteúdo orgânico e inorgânico contaminado do interior dos canais 1,2 . Para atingir tais objetivos, os canais são submetidos ao preparo químico mecâ-nico (PQM).O PQM é considerado um requisito chave para o sucesso da terapia endodôntica, uma vez que consiste na limpeza e modelagem -clean and shape-do
