Abstract
Objective: To assess the efficacy of 5% Glycolic Acid (GA), 17% ethylenediaminetetraacetic acid (EDTA) and 7% maleic acid (MA), in removing the smear layer (SL). Material and Methods: For the experiment, forty single-rooted human teeth were selected. To perform the chemo ‑ mechanical preparation, the root canals were instrumented to an apical size of #30, along with simultaneous irrigation of 2.5% NaOCl. The samples were allotted to the experimental groups based on the final irrigating solution (n=10): (1) The GA group: 05%, (2) the EDTA group: 17%, (3) the MA group: 7%, and (4) the control group: Distilled water. The teeth were evaluated for the presence or absence of SL using SEM. Results: Comparing the 5% GA, 7% MA and 17% EDTA groups, no statistically significant differences were found at the coronal and middle thirds (p>0.05). However, in the apical third, MA had greater efficacy than EDTA (p=0.002) and GA (p=0.041), with a significant difference in the SL removal, while there was no significant difference between the latter (p=0.148). Conclusion: Thus, it was concluded that 7% maleic acid as a final irrigating solution is more efficacious than 17% EDTA and 5% glycolic acid in eliminating the smear layer from the apical portion of the root canal.
期刊介绍:
The PESQUISA BRASILEIRA EM ODONTOPEDIATRIA E CLINICA INTEGRADA operates under a continuous publication online modality. This model results in annual volumes, without issue numbers. The main goal of the PESQUISA BRASILEIRA EM ODONTOPEDIATRIA E CLINICA INTEGRADA is to publish results from Original Research as well as Systematic Reviews in the fields of Dentistry and related sciences areas. Its abbreviated title is Pesqui. Bras. Odontopediatria Clin. Integr., and it should be used in bibliographies, footnotes, references and bibliographic strips. PESQUISA BRASILEIRA EM ODONTOPEDIATRIA E CLINICA INTEGRADA encourages submissions from all authors throughout the world. Manuscripts are judged by two experts solely on the basis of their contribution of original data and ideas and their presentation. All manuscripts must comply with Instruction to Authors. The following articles will be considered for publication: Editorials, Original Articles, Systematic Reviews, Short communications and Letters to the Editor.
