ABSTRACT Aim The aim of this in vitro study was to evaluate the apical seal obtained with four root canal sealers AH 26, Sealapex, Endoflas FS and AH Plus, with lateral condensation. Materials and methods Sixty root canals were prepared using the step-back technique. The specimens were divided into four experimental groups of 12 teeth and two control groups of 12 teeth. The experimental groups were obturated by laterally condensed gutta-percha with one of the tested sealers and control groups were obturated without any sealer. Methylene blue dye penetration with centrifuging method was used to evaluate the apical sealing ability. The quantitative apical leakage of each specimen was measured after 2 weeks. Results The results showed no significant differences between all groups except between AH Plus and Endoflas FS (<0.05). AH Plus showed significantly less leakage than Endoflas FS. Conclusion AH Plus showed the least leakage compared to AH 26, Sealapex and Endoflas FS. How to cite this article Joseph R, Singh S.

Introduction. Obturation of the root canal is the final phase of endodontic therapy and it is usually used to assess the quality of endodontic treatment. The objective of this study was to examine the quality of apical sealing of the root canal after application of chemically softened gutta-percha. Material and Methods. Thirty extracted single rooted and multi rooted teeth, divided into two groups according to the material for obturation, were used in the study. After root canal instrumentation using step-back technique, obturation was completed using chemically softened gutta-percha and AH Plus and Apexit paste. The effect of apical sealing was assessed regarding the type of material used for the obturation. After obturation, teeth were coated with two coats of varnish and immersed in 50% solution of silver nitrate for twelve hours, and then longitudinally cut using diamond disc. Linear dye penetration was observed using light microscope and twenty five times magnification. The apical leakage was calculated using the measuring scale, previously mounted on microscope lens. Results. The results showed that the average penetration of silver nitrate in single rooted teeth obturated with the AH Plus paste was 132.8 ?m, while in teeth obturated with Apexit, it was 148.6 ?m. The difference was not statistically significant. Apical leakage in multi rooted teeth obturated with softened gutta-percha and AH Plus paste was 117.3 ?m while in teeth obturated with Apexit, it was 158.5 ?m. The difference was statistically significant. Conclusion. The lowest dye penetration in the apical portion of the canal was observed in multi rooted teeth obturated with AH Plus paste and the highest penetration of silver nitrate was in multi rooted teeth obturated with Apexit paste.

ABSTRACTObjectives: The aim of this study was to assess the apical sealing ability of different core materials used with Epiphany™ sealer and to evaluate the effect of Resilon/Epiphany™ system on creating an apical mono-block seal.Methods: Fifty-five extracted human teeth were used. Forty-five were selected and randomly divided into three groups and ten teeth were used as positive and negative control groups. In Group 1, roots were obturated using Resilon™ and Epiphany™, In Group 2, roots were obturated using tapered single-cone gutta-percha and Epiphany™ and in Group 3, roots were obturated using Thermafil obturators and Epiphany™ sealer. The apical leakage was measured using the dye penetration methodology. The teeth were cleared, and the linear extent of dye penetration was measured with a stereomicroscope. Data were analyzed by the one-way ANOVA and Tukey HSD tests.Results: The teeth filled with Thermafil obturators and Epiphany™ sealer displayed the most apical leakage. The least apical leakage was shown with Resilon™ and Epiphany™. Groups 1 and 2 had significantly leaked less than Group 3.Conclusions: Based on the data of this study, although Resilon™ and Epiphany™ sealer showed the least apical leakage, statistical analysis showed no difference between gutta-percha and Epiphany™.

Introduction: Coronal microleakage is one of the most important factors for the success and longevity of endodontically treated teeth. Aim: The aim of this study was to evaluate in vitro the coronal microleakage in carious and intact teeth obturated with lateral compaction of gutta-percha using the dye penetration method. Materials and Methods: Forty extracted human teeth were allocated to two groups: Group I consisted of 20 intact teeth (10 single-rooted and 10 multi-rooted) and Group II comprised 20 carious teeth (10 single-rooted and 10 multi-rooted). Root canal preparation was performed using the Step-back technique and copious irrigation with 2.5% NaOCl. All root canals were obturated using lateral compaction and AH Plus endodontic sealer. The teeth were coronally filled with either CAVIT only or the combination of GIC and CAVIT, coated with 2 layers of nail varnish and immersed in 50% AgNO3. Afterwards, the teeth were sectioned mesio-distally using a diamond disc and linear dye penetration was evaluated using a stereo loupe with a micrometer scale at x6 magnification. Results: The results showed dye penetration in 70% of teeth filled with CAVIT and in 10% of teeth filled with GIC+CAVIT. The difference was statistically significant (p<0.05). Conclusion: Based on the obtained results, it may be concluded that the least coronal microleakage was observed in intact teeth temporarily filled with the GIC+CAVIT combination.

Objective: An in vitro comparison of coronal microleakage of three root canal sealers was performed using the dye leakage method. Methodology: Ninety-eight single-rooted human teeth were instrumented and randomly allocated to two groups. In the first group, root canals were treated with EDTA to remove the smear layer. The roots in both groups were obturated using laterally condensed gutta-percha and Sealapex, AH-26 or Ketac-Endo as the sealer. The teeth were suspended in 1% methylene blue dye for 6 days. The teeth were then rinsed, sectioned perpendicular to the long axis and evaluated for coronal dye penetration. Results: In general, Ketac-Endo root canal sealer showed greater dye penetration than Sealapex and AH-26. A statistically significant difference in the coronal penetration of the dye was found in the group with intact smear layer. Conclusion: Highly significant differences between AH-26 and Ketac-Endo (p < 0.001) and Sealapex and Ketac Endo (p < 0.001) were found.

Aim: The purpose of this study was to determine the influence of the smear layer on the coronal microleakage in root canals obturated with laterally condensed cold gutta-percha or Thermafil and two root canal sealers. Materials and methods: Sixty extracted single-rooted human teeth with straight root canals were allocated to two experimental groups. The root canals were instrumented using the STEP-BACK technique, K reamers and K files and irrigated with 2.5 % NaOCl. The teeth in the first group were treated with 17% EDTA and 2.5 % NaOCl to remove the smear layer. The teeth in both groups were obturated either with laterally condensed cold guttapercha (28 teeth) or Thermafil gutta-percha with plastic cores (28 teeth) and RSA or AH-PLUS sealers. The specimens were evaluated for coronal microleakage using silver nitrate solution. The linear penetration of the dye was assessed using a binocular magnifying glass (x25), with an inserted micrometer scale. Results: The results showed low coronal microleakage in the group where the smear layer was removed in both the lateral compaction technique (RSA - 1.71mm and AHPLUS - 1.61mm) and the Thermafil groups - RSA (1.65mm) and AH-PLUS (1.66mm). In the group with the intact smear layer, greater microleakage was noticed in both groups, lateral compaction technique -RSA (3.06 mm) and AH-PLUS (2.83mm) and Thermafil technique -RSA (2.99mm) and AH-PLUS ( 2.83mm). The difference was statistically significant between the groups with and without the smear layer for both RSA (p< 0.001) and AH-PLUS sealers ( p<0.001). Conclusion: The present results suggest that the removal of the smear layer significantly improves the tightness of the coronal seal and reduces the coronal microleakage.

OBJECTIVES: to compare the apical sealing ability of four root canal sealers. MATERIAL AND METHODS: forty extracted human maxillary canines were instrumented 1 mm short of the anatomical apex and randomly assigned to four groups (n=10), according to the root canal sealer used for obturation: Endofill, AH Plus, EndoREZ and Epiphany. Root canals were obturated with gutta-percha points, except for the Epiphany group, in which resin points (Resilon) were used. The teeth were immersed in India ink for seven days and clarified using methyl salicylate. The extent of apical dye penetration was measured with a measuroscope in all aspects of the canal. RESULTS: AH Plus (0.02 mm ± 0.07), Epiphany (0.00 mm ± 0.00) and EndoREZ (0.32 mm ± 0.62) did not differ statistically to each other (p>0.01). EndoFill presented the highest dye penetration mean (0.83 mm ± 0.73) and was statistically different from the other sealers (p<0.01). CONCLUSION: the resin-based root canal sealers presented lesser apical microleakage than the zinc oxide and eugenol based sealer. No statistical differences were observed among resin based sealers.
