“…Many products contain cetrimide because its addition improves the efficacy of irrigating solutions and is reported to have bactericidal and fungicidal properties. [ 12 17 ] In this SEM study, the main goal was to evaluate the effectiveness of 5.25% NaOCl with final rinse of 17% EDTA and Savlon™ irrigation solution used with EndoVac and EndoActivator for removing CH from the root canal walls. The results revealed that none of the methods used were efficient in removing the entire CH from the walls.…”

Aim:The aim of this scanning electron microscope study was to compare the efficacy of two techniques (EndoVac and EndoActivator) and two irrigating solutions (5.25% NaOCl in combination with 17% ethylenediaminetetraacetic acid vs. Savlon™) for removal of calcium hydroxide (CH) from the root canal walls.Settings and Design:The study was carried out in the specialty of conservative dentistry and endodontics.Materials and Methods:Forty single-canal human teeth were used. The specimens were de-coronated to obtain a standardized root length of 15 mm using a diamond disk. The canals were instrumented till F3 ProTaper and CH intracanal medicament placed in the root canal. One week later, teeth were randomly divided into one control group and six experimental groups according to different irrigation protocols with different techniques.Statistical Analysis:Kruskal–Wallis test was conducted to analyze the effect of different treatment measures with respect to three regions of tooth.Results:The results indicated that there was no statistically significant difference between the two irrigation solutions and two techniques.Conclusion:To achieve the best adaptation of filling material after root canal treatment, it is crucial to remove intracanal medication from the root canal walls. However, none of the irrigation regimens and different techniques were able to completely remove the CH from the root canal wall.

“…Many products contain cetrimide, because its addiction improves efficacy of irrigating solutions: cationic surfactants have been reported to have bactericidal and fungicidal properties. 17,18 Many studies reported the ability of chelating solutions to reduce or eliminate the smear layer, but no reports evaluated concentration of calcium ions removed from teeth with different chelators. 19 Accordingly, the objective of the present study was to evaluate and compare the influence of cetrimide on decalcifying capability of different irrigating solutions.…”

The objective of the present study was to evaluate and compare the influence of cetrimide on decalcifying capability of different irrigating solutions. Fifteen maxillary central incisor teeth has been collected. The canals were prepared in order to obtain four samples from each root. The specimens were randomly divided into 6 experimental groups (n=10) according to tested irrigating agents. Irrigating agents consisted in different composition of EDTA and citric acid solutions, addicted or not with cetrimide. Each specimen was submitted to three successive 5-min immersions in each solution. After exposures, the concentration of Ca2+ extracted was measured by inductively coupled plasma-atomic emission spectrometry (ICP-AES). Data were analysed by means of Kruskal Wallis and Mann Whitney tests. Significance was predetermined at p < 0.05. For all irrigants, the amounts of Ca2+ extracted from root canal dentin samples at 10 minutes were not significantly different from values reported after 15 minutes respectively. Therefore, for all irrigants tested, 10 minutes of application are sufficient to obtain maximum Ca2+ release. Moreover citric acid based agents observed a higher release of Ca2+. The addition of cetrimide did not affect the decalcifying capability of the EDTA and citric acid solutions.

The aim was to assess the presence of smear layer after canal instrumentation with two reciprocating rotary systems and a continuous motion one. Thirty canals were shaped with Reciproc, WaveOne or Mtwo systems. Smear layer was assessed following a three value scale at coronal, middle and apical levels with a scanning electron microscopy. Reciproc scores: coronal third, 20% of the cases: 0, 60%: 1, 20%: 2; middle third, 10%: 0, 20%: 1, 70%:2; apical third: 2 in all cases. WaveOne scores: coronal third, 0 (40%), 1 (30%) and 2 (30%); middle third, 0 (20%), 1 (50%), 2 (30%); apical third, 0 (20%), 2 (80%) of cases. MTwo scores: coronal third 0 (50%), 1 (30%) 2 (20%); middle third 0 (20%), 1 (50%), 2 (30%); apical third, 0 (10%), 1 (10%), 2 (80%). No significant differences (p>0.05) were found between the three used systems. Key words:Endodontics, reciprocating motion files, rotary file, SEM, smear layer.
