The aim of our study was to measure the cleaning efficiency of irrigating solutions used during endodontic treatment regarding smear layer removal from the root canal dentin walls. Ethylenediaminotetraacetic acid (EDTA) 17%, citric acid (CA) 10% and sodium hypochlorite (NaOCl) 2,5 % solutions were tested as final irrigating solutions. The study was conducted on extracted teeth, divided in four groups according to the irrigation protocol used. The specimens were analyzed by scanning electron microscopy and the amount of smear layer present at apical, middle and coronal level was recorded, based on a scoring system. Data were statistically analyzed using Kruskal-Wallis and Friedman test and the level of significance was set at p<0.05. In the coronal and middle segments of dental roots we noticed no statistically significant difference between EDTA and CA in smear layer removing capacity. Final irrigation with 17% EDTA proved to be more efficient than 10% CA and 2,5% NaOCl in smear layer removal at apical level of the root canal, with p<0.05 (p=0.042), which is an important area for disinfection in endodontic treatment.

Background: Root canal irrigation is one of the most important stages during root canal treatment. One of the requirements of root canal irrigation material is that it can eradicate the smear layer but does not alter the physical properties of the root canal dentin. Objective: To investigate the effect of chitosan nanoparticle as a final irrigation solution on the smear layer removal, micro-hardness and surface roughness of root canal dentin. Methods: Seventy-two premolars used in this study and divided by three evaluations, namely smear layer removal, micro-hardness and surface roughness. Each study used 24 teeth and was assigned randomly into three groups of eight teeth. Group-1, final irrigation with 17% EDTA; group-2, with 0.2% chitosan nanoparticles; group-3, with 2.5% NaOCl. Specimens were evaluated for smear layer removal, micro-hardness and surface roughness using a Scanning Electron Microscope, Vickers hardness tester and surface roughness measuring instrument, respectively. Data obtained from smear layer removal evaluation were statically analyzed using Kruskal-Wallis and Mann-Whitney U and data from micro-hardness and surface roughness were analyzed using one-way ANOVA and Tukey’s test. Results: Final irrigation using 0.2% chitosan nanoparticles produced similar smear layer removal than 17% EDTA (P>0.05), but it was greater than 2.5% NaOCl (P<0.05). Chitosan had higher micro-hardness and lower surface roughness than EDTA (P<0.05), but it was the same as 2.5% NaOCl (P>0.05). Conclusion: Final irrigation using 0.2% chitosan nanoparticles had the same effect on smear layer removal compared to 17% EDTA; however, 0.2% chitosan produced higher micro-hardness and lower surface roughness of root canal dentin than 17% EDTA.

Introduction: Sodium Hypochlorite (NaOCl) remains gold standard as a result of its antimicrobial effect and tissue dissolution properties, but it has no effect on inorganic portion of smear layer. Thus the combination of NaOCl and EDTA has been proven to have the perfect ability in removal of both organic and inorganic debris. These irrigants when used with conventional syringe irrigation were unable to penetrate the apical portion of the root canal, so new activation devices have come in the market which claims to be effective in delivering the irrigant to the working length. Objective/Aim: This study evaluated and compared the efficacy of recently introduced irrigation activation devices EndoActivator, Passive ultrasonic irrigation and Laser on removal of smear layer from the apical third of instrumented root canal using Scanning electron microscope. Methods: Forty three single rooted teeth were prepared with the help of protaper files and divided into four groups. Group I: EDTA only, Group II: Endoactivator, Group III: Laser, Group IV: Passive Ultrasonic Irrigation (PUI). Three specimens were not treated with any smear layer removal protocol and were immediately sectioned and sent for SEM examination. The remaining 40 samples from 4 groups after treatment with different activation system were also sectioned and sent for SEM examination. The data obtained were statistically analysed using Friedman’s test. Results: All the four groups removed smear layer and the laser showed best smear layer removing capability compared to other groups but was significant only with respect to control and group I (EDTA group without any activation) (p<0.05). Conclusions: Within the limitations of the study, all the activation systems were able to remove the smear layer from the apical third of the root canal with laser showing the best result followed by Endoactivator and then PUI.
