“…Irrigation is essential for gross debridement, lubrication, dissolution of tissues, destruction of microrganisms and helps in cleaning areas that are inaccessible for mechanical cleansing. Apart from beneficial effects, irrigants may exhibit detrimental effects on the dentin or root canal filling materials (2) .…”

Purpose Assessment of the surface roughness of root canal and its correlation with Resin Sealer Bond Strength following final irrigation by apple vinegar. Material and methods 50 extracted lower premolars were selected and prepared using Universal ProTaper rotary files and 14 ml 2.6% NaOCL then the samples were equally distributed into 2 main groups (20 samples each) depending on the type of the final rinse. Group I: Apple vinegar (AV), Group II: 17 % Ethylenediamine tetra acetic acid (EDTA), Control group (10 samples): sterile saline. Each main group was further equally distributed into 2subgroups (10 samples each). Subgroup A: For surface roughness evaluation. Subgroup B: For push out bond strength evaluation. Surface roughness was evaluated using digital microscope. The push out bond strength test was carried on using universal testing machine. The sealer penetration inside the dentinal tubules was seen under scanning electron microscope (SEM) in selected samples. Results Regarding the results of subgroup A, at all levels, the highest value of the average roughness deviation (Ra) was recorded in samples treated with 17% EDTA, while the lowest value was recorded with the saline group and there was no statistical significant difference among the tested groups. Regarding the results of subgroup B, at all levels, the highest median push out bond strength was recorded in samples treated with 17% EDTA, while the lowest value was recorded with the saline group and there was no statistical significant difference among the tested groups except at the apical levels where the difference statistically significant among the tested groups. SEM observation of sealer/ dentin interface revealed few traces of sealer penetration with samples treated with 17% EDTA and AV. Conclusion EDTA 17% as a final rinse produced higher value of surface roughness compared to AV. The push out bond strength results of AV was comparable to that of 17%EDTA when applicated as a final rinse. There is a linear relation between Ra and the push out bond strength of resin sealer in Groups I, II.

“…7 18% HEBP, also known as etidronic acid, is a substance that is a selective chelator because of its minimal ramifications on the dentin structure and can even be used in combination with NaOCl without interfering with its antimicrobial property. 1 Hulsmann et al stated that HEBP shows lesser chelating ability, which causes minimum alterations in the flexural strength and apatite/collagen ratio of mineralized dentin. 2 Cobankara et al evaluated the chelation effect of 17% EDTA, 18% HEBP, citric acid, and peracetic acid.…”

“…They concluded that if antimicrobial activity and effect on the root dentin microhardness were the only requirements of an endodontic irrigant, the results of this study would suggest that Propolis is equal to NaOCl. 1 Elgendy evaluated the comparative action on microhardness of 0.2% chitosan, 4% Propolis, 5% NaOCl, and 17% EDTA on human root dentin. He found out that significant decrease in the microhardness of root dentin was seen with 4% Propolis.…”

“…Reports have indicated that the use of popular irrigants ethylenediamine tetra-acetic acid (EDTA) and sodium hypochlorite (NaOCl) can demonstrate erosion of canal walls. 1 The recently introduced irrigant hydroxyethylidene bisphosphonate (HEBP) also known as etidronate, shows lesser chelating ability, which causes minimal modifications in the flexural strength of mineralized dentin and hydroxyapatite/collagen ratio. An alternate irrigation protocol with HEBP has been suggested as a replacement to EDTA, because of its mild chelating ability.…”

Aim and Objective The present in vitro study was done to comparatively evaluate the effect of different endodontic irrigation protocols on the microhardness at coronal, middle, and apical levels of root canal dentin. Method The total sample size for the study was 100. Each sample consisted of a longitudinally sectioned half of a root of a single-rooted tooth, which was then embedded in acrylic resin. The prepared samples were divided randomly into five groups of twenty samples each. Each group was treated with its respective irrigant to be tested. Group I was the control—the specimens were treated with distilled water. The specimens in group II were treated with sodium hypochlorite (NaOCl), followed by ethylenediamine tetra-acetic acid (EDTA). Specimens in group III were treated with NaOCl, followed by CHX. Specimens in group IV were treated with NaOCl, followed by hydroxyethylidene bisphosphonate (HEBP), and specimens in group V were treated with NaOCl, followed by propolis. Following this, all the samples were placed on the Vickers microhardness tester, and the results were tabulated and statistically analyzed to determine the irrigant solutions' effect on the microhardness of root dentin at coronal, middle, and apical third. Results Intergroup comparison of various irrigants showed that 18% HEBP showed the least reduction in the microhardness values of root canal dentin, and 17% EDTA caused the maximum decrease in microhardness values with a significant difference. When the baseline values were compared with the values after the use of experimental solutions in all the groups, it was observed that the microhardness gradually decreased from coronal to apical third of root dentin. Conclusion On the basis of the results obtained, it can be concluded that weak chelators such as 18% HEBP do not affect the microhardness considerably, and that they can be used in future in place of strong chelators, that is, EDTA, which make root dentin weak by more microhardness reduction.

Objective Objective was to investigate the effect of NovaMin toothpaste and two experimental toothpastes on surface microhardness of hypersensitive dentin. Methods Eighty specimens were prepared and divided randomly into eight groups (n = 10/group) according to the tested toothpastes (NovaMin, moringa and propolis toothpastes) and the acidic challenge (with or without 6% citric acid challenge). Enamel surfaces were removed, and the dentin surfaces were exposed on which the three tested toothpastes were brushed twice a day for 1 week using an electric toothbrush, then a 4-d citric acid cycling model with pH 5 was performed. The prepared specimens were stored in artificial saliva until the microhardness test was performed. Statistical analysis was done using One-way ANOVA followed by Tukey post hoc test. Results NovaMin-containing toothpaste showed an increased dentin surface microhardness following a week of twice daily brushing compared to other groups. However, NovaMin-containing toothpaste showed the highest microhardness values following pH cycling with citric acid of pH 5 compared to other tested groups. Conclusions NovaMin-containing toothpaste showed a partial recovery of dentin microhardness at pH 5 during the acidic challenge. Moreover, propolis- and moringa-containing toothpastes had an insignificant effect on dentin surface microhardness with and without citric acid challenge.
