Smear layer removal with citric acid solution

Abstract

The aim of this study was to evaluate efficacy in smear layer removal of 17% EDTA and 10% citric acid, using SEM. Material and method: Twenty human, extracted teeth with a single root canal were examined. Whilst instrumentation with step-back technique and manual K files, root canals were irrigated with 2 ml of 2.5% NaOCl, between each file size. After instrumentatio n, specimens were divided into two groups. The first group was irrigated with a final flush of 17% EDTA, during one minute, and the second group was irrigated with a 10% citric acid. Results: Irrigation with 17% EDTA and 10% citric acid removed smear layer from the root canals walls. There was not statistically significant differences (p>0.05) in cleaning ability between EDTA and citric acid groups.

Cilj ovog istraživanja je bio da se pomoću SEMa proveri efikasnost 10% rastvora limunske kiseline u uklanjanju razmaznog sloja sa zidova kanala korena zuba. Materijal i metod: Istraživanje je obuhvatilo 20 jednokorenih,ekstrahovanih humanih zuba.Svi uzorci su instrumentirani step-back tehnikom i ručnim K turpijama,a tokom instrumentacije ispirani 2,5 % rastvorom NaOCla. Uzorci su zatim podeljeni u 2 eksperimentalne grupe. Prva grupa uzoraka je tokom finalnog ispiranja tretirana sa 17 % rastvorom EDTA, tokom 1 minuta,a druga grupa 10 % rastvorom limunske kiseline, po istom protokolu. Rezultati:Dobijeni rezultati su pokazali da se primenom 17 % rastvora EDTA i 10 % rastvora limunske kiseline postiže efikasno uklanjanje razmaznog sloja sa zidova kanala korena.Između ispitivanih sredstava nije bilo statistički značajne razlike (p>0.05).
