“…These results are in agreement with those of several previous studies, 8,12,27,28,29 in which these solutions also reduced microhardness. This effect is desirable in the layer next to the canal lumen and it has been associated with increasing calcium loss, resulting in dentin demineralization and softening.…”

This study aimed to evaluate the effect of final irrigation protocols on microhardness reduction and erosion of root canal dentin. Sixty root canals from mandibular incisors were instrumented and randomly divided into six groups (n = 10) according to the irrigant used: QMiX, 17% EDTA, 10% citric acid (CA), 1% peracetic acid (PA), 2.5% NaOCl (solution control), and distilled water (negative control). The chelating solutions were used to irrigate the canal followed by 2.5% NaOCl as a final flush. After the irrigation protocols, all specimens were rinsed with 10 mL of distilled water to remove any residue of the chemical solutions. Before and after the final irrigation protocols, dentin microhardness was measured with a Knoop indenter. Three indentations were made at 100 µm and 500 µm from the root canal lumen. Afterwards, the specimens were prepared for scanning electron microscopic analysis and the amount of dentin erosion was examined. Wilcoxon and Kruskal-Wallis tests were used to analyze the results with a significance level set at 5%. At 100 µm, all protocols significantly reduced dentin microhardness (p < .05), while at 500 µm, this effect was detected only in the EDTA and QMiX groups (p < .05). CA was the irrigant that caused more extensive erosion in dentinal tubules, followed by PA and EDTA. QMiX opened dentinal tubules, but did not cause dentin erosion. Results suggest that QMiX and 17% EDTA reduced dentin microhardness at a greater depth. Additionally, QMiX did not cause dentin erosion.

“…The MCJ has antimicrobial efficacy against E. faecalis , which could be attributed to the presence of L-asperuloside, alizarin, acubin and scopoletin [ 20 , 67 , 117 ]. Das et al [ 119 ] compared the effect of microhardness of the dentin when treated with MCJ and Q mix. They showed that Q Mix regimen did not hamper the micro hardness when compared to MCJ.…”

Complete eradication of microbial biofilms and elimination of the smear layer are the key factors during endodontic treatment. Various chemical irrigants have been proposed in the literature for the same. The major setback with these chemical irrigants is that they are not bio-friendly to the dental and peri-radicular tissues. In the recent years, research to use natural products for root canal disinfection has gained importance. The aim of this article is to compile various herbal products that have been used as an irrigants and intracanal medicaments in the field of Endodontics to eradicate the biofilm and remove smear layer.

“…Ghisi et al (20) found that EDTA with or without NaOCL have the most powerful effect in microhardness reduction against super-oxidized water and distilled water. Kottor et al (21) found that EDTA/NaOCL have greater effect in microhardness reduction than Qmix/NaOCL. Nikhil et al (22) found that Dentin microhardness was decreased more by EDTA than chitosan.…”

Background: Increased Dentin Brittleness means it is weaker and more liable to fracture under occlusal forces which adversely affects the strength of the tooth, the prognosis of the endodontic treatment, and the life time of the tooth under the occlusion forces. Irrigation solutions have different effects on the micro hardness and the micromorphology of the root canal dentin. Aim:The current study was done to evaluate the effect of two different nano irrigating solutions on the dentin microhardness. Materials and methods:Sixteen intact human maxillary incisors with mature apices were decoronated, after cleaning and shaping all the roots were longitudinally split by using Isomet. To get total of 32 root halves. Each root half was horizontally embedded in auto polymerized acrylic resin exposing the most dentin surface. Each root half was given a number and distributed into four equal groups. Group I Nano Magnesium oxide, Group II Chlorhexidine loaded chitosan nano particles, Group III 5.2% Sodium hypochlorite followed by 17% EDTA and Group IV Saline. Each half was immersed in the tested solution for 5 min. The microhardness of the root dentin was assessed by vicker's microhardness indenter Results: Group III shoed statistically significant reduction in dentin microhardness compared to other groups. Conclusion:CHX+CSNPs and MgO are suitable endodontic solutions because of their lower toxic effect on microhardness in comparison to 5.25NaOCL + 17% EDTA.
