“…It has been suggested that, although chemical substances can reduce tooth hardness, this change in hardness does not interfere with substrate resistance. 30 By contrast, Uzunoglu et al 17 showed that fracture resistance of endodontically treated roots was differently affected by the various EDTA concentrations, followed by irrigation with NaOCl, at different exposure times.…”

Effect of final irrigation protocols on microhardness reduction and erosion of root canal dentin

et al. 2017

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.

“…12,14,15,16 Some studies have suggested that these changes could increase the susceptibility to tooth fracture. 17 A solution known as QMiX has been suggested in the literature. This irrigant is ready for use and contains EDTA, chlorhexidine, and a detergent, with a slightly alkaline pH.…”

“…Because case reports and studies have shown that minocycline causes visible crown discoloration (15)(16) , and significant reduction in tooth fracture resistance (17-18) ; as it causes demineralization of intertubular dentin by binding to calcium ions via chelation to form an insoluble complex and become incorporated into the tooth matrix causing the discoloration (19) and reduction in phosphate/amide ratio and microhardness of dentin. Also the acidity of TAP (PH = 2.9) is more than that of DAP (PH = 3.4) having a more demineralization effect on the intertubular dentin, causing significant reduction in phosphate/amide ratio and decrease in the dentin microhardness and fracture resistance (20)(21).…”

“…Chelating agents also reduce the resistance of the root to fracture, and the use of 17% EDTA for 10 min and 1% NaOCl for one minute reduces the resistance to root fracture by approximately 1.5 times, while lower concentrations of EDTA (5%) and shorter exposure times (one minute) cause a smaller reduction in resistance (81).…”
