(1) Aim: This study aims to analyze the in vitro infiltration of a silicate root canal sealer into dentinal tubules after using different endodontic irrigating solutions. (2) Methods: Twenty-nine teeth with single roots were separated into three groups according to the final irrigation protocol: G1 n = 10) = 17% EDTA (ethylenediaminetetraacetic acid) + 3.0% sodium hypochlorite (NaOCl), G2 (n = 10) = 17% EDTA + 2.0% chlorhexidine and G3 (Control group, n = 9) = 17% EDTA + saline solution. Root canals were filled using cold lateral compaction technique with MTA Fillapex sealer and gutta-percha. The sealer was labeled with rhodamine B. The teeth were segmented at the middle and third apical sections, which were visualized using 10× confocal laser microscopy to determine the sealer penetration percentage. (3) Results: In the apical section, no statistically significant differences were found between the groups regarding sealer penetration. In the middle section, Group 1 obtained the highest percentage, and Group 2 the lowest (p = 0.004). Group 1 also presented statistically significant differences in the Control Group (p = 0.031) and had close sealer penetration values. Meanwhile, the Control Group (p = 0.023) and Group 2 (p = 0.029) revealed a significant decrease of sealer penetration between the apical and middle sections. (4) Conclusion: The obtained results support that final irrigation with NaOCl promoted similar sealer penetration in the apical and middle sections. On the other hand, a significant decrease in the sealer penetration of the middle section was observed for the chlorhexidine and saline groups. Compared to other irrigant solutions, NaOCl promotes more uniform sealer penetration, which can correlate with better sealing and, consequently, higher endodontic treatment success.

Introduction: The purpose of this study is to examine the effect of different chelating solutions on microhardness and surface roughness of root canal dentin. Methodology: The crowns of sixty recently extracted maxillary central incisors were separated by diamond burs from the cemento-enamel junction. Roots are divided longitudinally into two pieces with diamond saw. The obtained samples were embedded in autopolymeric-acrylic and the dentin-surfaces of the teeth were grounded. Micro-hardness and surface-roughness measurements were carried out before the chelating processes. First group, the specimens were treated with gel-formed 17% Ethylenediaminetetraacetic acid [EDTA] (JE), second group, specimens were treated with 17% Liquid-formed EDTA (LE), third group, specimens were treated with 20% Citric acid (CA), and the last group specimens were treated with 7% Maleic acid (MA) for 120 seconds. After application of the chelating agents, micro-hardness and surface-roughness measurements of all samples were performed again. The difference between the initial and final measurements was calculated and statistically analyzed. One Way Analysis of Variance ANOVA was used for statistical-analysis and statistically significant difference was observed between the groups (p <0.05). Results: According to the test results, the microhardness of LE was statistically equal to that of JE and caused the least decrease in micro-hardness, SA decreased micro-hardness more than LE and JE, and MA decreased dentin micro-hardness more than all other solutions. And surface-roughness results are: MA increased surface-roughness more than other groups, SA and JE less roughened the dentin surface than MA, and there was no significant difference between the two solutions, LE caused less increase in dentin surface roughness compared to all solutions. Conclusions: Besides the use of EDTA and SA, the clinical use of MA can be considered, and it should also be noted that EDTA differs in terms of surface roughness between liquid and gel forms.   How to cite this article: Topbaş C, Adıgüzel Ö, Çölgeçen Ö.

ABSTRACT Objective: The objective was to investigate the effect of intracanal antibiotic medicaments followed by ethylenediaminetetraacetic acid (EDTA) on the indentation properties and hardness of radicular dentin using a BioDent reference point indenter and a traditional microhardness technique, respectively. Materials and Methods: Specimens with intact root canal dentin surfaces and polished radicular dentin specimens were obtained from immature human premolars. Each type of specimen was randomly assigned (n = 10 per group) and treated with either double antibiotic paste (DAP) for 4-week followed by EDTA for 5 min, triple antibiotic paste (TAP) for 4-week followed by EDTA for 5 min, EDTA for 5 min or Hank's balanced salt solution (control). The BioDent reference point indentor and Vickers microhardness tester were used to measure the indentation properties of root canal surfaces and the hardness of polished dentin specimens, respectively. One-way ANOVA followed by Fisher's protected least significant differences were used for statistical analyses. Results: Both types of radicular dentin treated with antibiotic pastes and/or EDTA had a significant increase in the majority of indentation properties and a significant reduction in hardness compared to the untreated dentin. Furthermore, treatment of dentin with antibiotic pastes and EDTA caused significant increases in indentation properties and a significant reduction in hardness compared to EDTA-treated dentin. However, the RPI technique was not able to significantly differentiate between DAP + EDTA and TAP + EDTA-treated dentin. Conclusion: Dentin treated with antibiotic medicaments followed by EDTA had a significant increase the indentation properties and significantly reduction in hardness of radicular dentin.

Purpose. Debonding from the root canal dentin is the most common failure mode of fiber posts. This study aimed to assess the effects of cold atmospheric argon plasma (CAAP) and ethylenediaminetetraacetic acid (EDTA) on micro-push-out bond strength of fiber posts to root canal dentin. Materials and Methods. Forty maxillary canine teeth were decoronated, underwent endodontic treatment, and were stored in an incubator for 7 days. After post space preparation, the teeth were randomly divided into four groups for different surface treatments: (I) saline, (II) 17% EDTA, (III) CAAP, and (IV) 17% EDTA + CAAP. Fiber posts (Whitepost no. 2, FGM) were cemented into the root canals using Panavia F2.0 resin cement, and 1 mm-thick sections were made at the coronal, middle, and apical thirds of the roots. The samples underwent micro-push-out bond strength test. The mode of failure was also determined under a stereomicroscope. Data were analyzed using three-way ANOVA and Tukey’s post hoc test (α = 0.05). The mode of failure data were analyzed using the chi-square test. Results. The mean micro-push-out bond strength of fiber posts was not significantly different in the four groups ( P > 0.05 ). However, the bond strength values in the coronal third were significantly higher than the corresponding values in the apical third ( P = 0.01 ). There was no significant difference in the modes of failure between the groups ( P > 0.05 ). Conclusion. Application of CAAP alone or in combination with 17% EDTA could not successfully increase the bond strength of fiber posts to root canal dentin.

ABSTRACT Aim To compare the effect of QMix, a mixture of tetracycline, citric acid, and detergent (MTAD), and ethylenediaminetetracetic acid (EDTA) on the microhardness of the root canal dentin. Materials and methods A total of 30 single-rooted teeth were decoronated at 15 mm from the root apex. Root canal instrumen- tation using step back technique was done and the specimens were split into two halves using diamond disc. These were embedded in acrylic blocks and sent for testing by Vickers hard- ness test. The other half of the specimens was divided into four groups. Control group: In this, normal saline was used. Group I: MTAD was used. Group II: 17% EDTA was used. Group IV: QMix 2 in 1 (DENTSPLY) was used. The specimens were immersed in test irrigant for 5 minutes in closed glass plates. The tested specimens were sent for Vickers hardness test under 100 gm load for 15 seconds. The post Vickers hardness number readings were recorded and sent for statistical analysis. Results Data were analyzed using one-way analysis of variance and least significant difference post hoc test was applied for pairwise comparison. QMix showed significantly less reduction in microhardness than EDTA and QMix: Normal saline > QMix>EDTA>MTAD. Conclusion QMix as a root canal irrigant is efficient as it caused least reduction of microhardness of dentin. It has antibacterial properties and is also efficient for smear layer removal.
