“…Over the last two years, research has focused on the use of preheated chelating agents in their efficiency in the removal of the smear layer, and in improving the bond strength [ 37 ]. Better results were shown when preheated EDTA was used [ 37 ]. The above-mentioned was in corroboration with another study which had mentioned similar results [ 38 ].…”

This systematic review aimed to compare the efficacy of herbal agents with ethylene diamine tetraacetic acid (EDTA) in removing the smear layer during root canal instrumentation. The research question in the present study was to assess: “Is there a significant difference in reducing smear layer comparing EDTA and herbal agents?” Electronic databases (PubMed, Scopus, and Web of Science) were searched from their start dates to April 2022 using strict inclusion and exclusion criteria, and reviewed following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020 guidelines. Only in vitro studies comparing herbal agents with EDTA were included in the current systematic review. Two reviewers independently assessed the included articles. A total of 625 articles were obtained from an electronic database. Eighteen papers were included for review of the full text, out of which, ten papers were excluded because they did not meet the inclusion criteria. Finally, eight articles were included in the systematic review. The present systematic review considered only in vitro studies; hence, the result cannot be completely translated to strict clinical conditions. The results of the present systematic review have shown that quixabeira, morindacitrifolia, oregano extract, and neem show better smear layer removal compared to other herbal agents, whereas they showed reduced smear layer removal when compared with EDTA. Although, it was seen that most of the included studies did not report a high quality of evidence. Hence, the present systematic review concludes that herbal agents have reported to show inferior smear layer removal when compared to EDTA. Thus, as far as herbal based alternatives are concerned, there is no highest level of evidence to state its real benefit when used as a chelating root canal irrigant.

“…The optimal wettability of root canal walls depends on the surface tension of the chemical solution used and the surface energy of root canal dentin ( 2 ). Preheating the chemical solution reduces surface tension and increases tissue dissolving properties without any change in their short-term stability ( 13 , 14 ). Higher temperature may enhance surface wetting ability and penetration of solutions into the dentin tubules, as well as the effect of killing the endodontic microbiota ( 15 ).…”

Background The heating of chelating agents such as EDTA increases dentin wettability by decreasing surface tension. However, the calcium ion release effect of preheated chelating agents in instrumented root canals has not yet been mentioned. In this study, it was aimed to evaluate the number of calcium ions removed by the pre-heated chelating agents from the root canals. Material and Methods After 51 bovine teeth were instrumented, three of them were separated as negative controls and the remaining teeth were divided into six groups according to the temperature of the solution (at 22 or 37ºC): EDTA-22, CITRIC-22, QMix-22, EDTA-37, CITRIC-37 and QMix-37. Following irrigation, calcium ion levels were determined by atomic absorption spectrophotometer in chelating agents collected from the root canals. Results QMix solution eliminated significantly more calcium ions than other chelating agents at different temperatures ( p < 0.05). Regardless of the heating, QMix and 17% EDTA were significantly superior to 40% Citric acid ( p < 0.05) while no significant difference was detected between QMix and 17% EDTA groups ( p < 0.05). Heating all chelating agents did not significantly increase their ability to remove calcium ions from pre-instrumented root canals ( P < 0.05). In the SEM examination, it was observed that the smear layer was removed from the middle third of the roots, except for the negative control group. Conclusions Temperature changes have shown that these agents do not increase the ability of the smear layer to dissolve the inorganic structure. QMix at different temperatures may be recommended to use as the final chelating agent. Key words: EDTA, citric acid, QMix, calcium ions, temperature.

“…In some cases of endodontically treated teeth, intra-canal posts are considered essential in order to enhance the final restoration retention. Compared to cast metal and core systems, fiber posts became more usable due to their better esthetics, closer elastic modulus to that of dentin, and more uniform stress distribution (1)(2)(3).…”

“…Debonding of the fiber posts at the adhesive resin-dentin junction is considered to be their most common failure reason, which is thought out to be a sequel of the thick smear layer and debris covering the root surface formed during post space preparation (1)(2)(3) .…”

“…Ethylene diamine tetra acetic acid (EDTA) is another irrigant solution that effectively dissolves the inorganic materials; however, it does not possess antibacterial activity (2,12) . Consequently, removal of the organic and inorganic components of the smear layer can be achieved by using an irrigant combining both sodium hypochlorite (NaOCl) and EDTA solutions; NaOCl acts as an organic tissue solvent and has a bactericidal action while the chelating effect of EDTA promotes decalcification of the inorganic components exposing the dentin collagen network (13) .…”

Background;The smear layer is considered an obstacle limiting the penetration of adhesive types of cement into the dentinal tubules, thus adversely affecting the bond strength of the fiber posts. Objective;The purpose of this study was to assess the effect of ultra-sonic activation on the bond strength of fiber posts, cemented with self-adhesive cement to the root dentin.Methods; A total of 18 recently extracted single rooted premolars were selected. The root canals were prepared using ProTaper rotary, samples were obturated with Protaper universal gutta percha points. Post space was prepared using gates glidden drills, specimens were randomly divided into two groups of n=9 according to the irrigation application techniques; Group 1: conventional syringe, Group 2: ultra-sonic activation. Posts were cemented using Rely X Unicem2, bond strength was determined by pull out test.Results; A statistically significant higher mean value was recorded in Group 2 compared to Group 1.Conclusions; Ultrasonic activation can aid the irrigation with 2.6% NaOCl followed by 17% EDTA in smear layer removal, contributing in a triad way of cleaning of the root canal system and thus promoting the bond strength of fiber posts.
