The purpose of the study is to assess the apical sealing ability of the endodontic space using two types of canal filling techniques: vertical compaction of warm gutta-percha and AhPlus sealer compared with Resilon and RealSeal SE. Two sets of extracted human teeth were prepared with rotary instruments, each 20 teeth being obturated by the two techniques: the classical and the adhesive root canal filling. The apical leakage of the root canal filling made with Resilon and RealSeal SE was higher than the one with gutta-percha and AhPlus. The difference was statistically significant.

The objective of root canal obturation is to achieve a fluid-tight seal. Recently, GuttaFlow bioseal (GB), a root canal sealer composed of polydimethylsiloxane, gutta-percha particles, and bioactive glass ceramics, has been developed, to enhance the sealing ability of root canal filling material. The objective of this study was to assess the sealing ability of GB using a subnanoliter-scaled fluid-flow measuring device and to compare with that of AH Plus (AH). The fluid flow in root canal-filled teeth using either gutta-percha cone (GP) with AH (GAR; n = 10) or GP with GB (GBR; n = 10) and in GP inserted in AH blocks (GA; n = 10) or GP inserted in GB blocks (GB; n = 10) was measured. In addition, fluid flow in sealer blocks of AH (A; n = 10) and GB (B; n = 10), which served as negative controls, was measured. Root canal-filled teeth using GP without any sealer (GR) acted as positive controls (n = 10). The leakage was obtained by calculating the volume of moved water by time (s), after stabilization of the fluid flow was achieved. Statistical analysis was performed using the Kruskal–Wallis test and Mann–Whitney U-test with Bonferroni correction. A p value less than 0.00238 (0.05/21) was considered significantly different. The mean leakages (nL/s) in the groups are as follows: GAR, 0.0958 ± 0.0543; GBR, 0.0223 ± 0.0246; GA, 0.0644 ± 0.0803; GB, 0.0267 ± 0.0182; A, 0.0055 ± 0.0057; B, 0.0052 ± 0.005; and GR, 0.2892 ± 0.3018. The mean leakage in the GBR group was lower than that in the GAR group (p = 0.001), while the mean leakages in the GA and GB groups were not significantly different. GuttaFlow bioseal can be useful in single-cone obturation technique.

Background: Root canal irrigation seeks the elimination of bacteria and its products from the root canal. If debris is left in the root canal, it can prohibit adaptation between obturationmaterial and root canal wall. Therefore, it can decrease the sealing ability of obturation material. Purpose: To assess the effectiveness of 2.5% NaOCl and 17% EDTA on the apical sealing ability of resin obturation paste. Method: The roots of 18 human mandibular premolar teeth were selected and the root canal was prepared using a conventional technique. Samples were irrigated with 2.5% NaOCl, and17% EDTA, and sterile aquadest (Aqua Deastilata) as a control group. Samples were filled with gutta-percha and top seal. Samples were soaked in 2% methylene blue for 48 hours to measure the depth of microleakage. Result: The mean apical leakage after irrigation with 2.5% NaOCl; 17% EDTA; and sterile aquadest in the sequence were 0.92 mm; 3.6 mm; and 8.08 mm. Conclusion: 2.5% NaOClhas less depth of microleakage than 17% EDTA. However, the depth of microleakage cannot demonstrate the exact sealing ability of the resin paste due to some factors.

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. An ideal endodontic sealer should adhere firmly both to dentin and to gutta-percha. Objective. The aim of this study was to evaluate the adhesion of the root canal filling to dentin and gutta-percha using scanning electronic microscopy (SEM). Methods. The sealing ability of endodontic sealers to dentinal walls of the root canal was assessed in recently extracted human single canal premolars. Twenty teeth were prepared using the crown-down technique and irrigated with 3% NaOCl. A total of 20 samples were divided into two groups. The root canals were obturated using Ketac-Endo Aplicap and GutaFlow. The sealing ability and adhesion properties at the sealer-dentin interface were studied using SEM and the results were rated from 1 to 3; extremely good adhesion (rated 1), good adhesion (rated 2) and a relatively good adhesion (rated 3). Results. The results showed extremely good adhesion on Ketac-Endo and GuttaFlow dentin interface. GuttaFlow has strong adhesion (rated 1) to gutta-percha in comparison with Ketac-Endo to gutta-percha interface (rated 2). Conclusion. New GuttaFlow filling material has a strong sealing ability and excellent adhesion to dentinal walls and gutta-percha cones. Ketac-Endo showed excellent bond to dentin with a slightly weaker adhesion capacity to the gutta-percha cones in comparison to GuttaFlow.

Aim: The aim of this study was to assess whether an obturation, combining a custom guttapercha cone with the BIOROOTTM-RCS sealer, displays similar sealing quality to the orthograde apical plugs of MTA CAPS1 in immature teeth with irregular wide apices. Methodology: Thirty-four immature permanent premolars with apical diameter varying between (1-3 mm) were chosen for this study and were divided into two groups. They were imbedded in wet sponge, which simulated the periapex. In the first group; 5 mm orthograde plugs of MTAwere placed using an appropriate plugger. In the second group; a custom gutta-percha cone was fabricated and used for root canal filling with the BIOROOTTM-RCS sealer. The specimens were stored at 37 8C and 100% humidity during five weeks to allow the complete set of the filling materials. The apical leakage was evaluated using a dye penetration test with 50%-weight silver-nitrate. The teeth were then embedded in a transparent resin and sectioned transversally at 1 and 3 mm from the apex. The slices were examined under optical microscope and were given scores from (0) to (4). When scoring a slice was difficult, spectroscopy for energy dispersion using a scanning electron-microscope was used to confirm the score. The results were compared using the Fisher test with p < 0.05. Results: Silver-nitrate was found in both groups in all slices at 1 mm. At 3 mm, the difference of micro-leakage was not significant. Conclusions: The custom gutta-percha cone combined with BIOROOTtm-RCS sealer displays similar leakage resistance to the orthograde MTA plugs.

Level Of Significance

Introduction. Root canal filling material may be extruded during retreatment through the apical foramen and cause flare-up or chronic infection. The aim of this study was to compare the apical extrusion of gutta-percha and resilon filling materials during retreatment using hand and rotary instruments. Methods. Sixty extracted single-rooted teeth with single, straight canal were selected. Canals were prepared with ProTaper Universal rotary system to a size F2. Two groups (30 teeth in each) were filled with gutta-percha or resilon points, respectively. In both groups teeth were randomly divided into the three subgroups (10 teeth in each), based on the instruments used for retreatment: Hedstrom hand files and two rotary groups- ProTaper and Twisted File instruments. Apical extrusion was detected visually, using a 4-degree scoring system. Mean scores were calculated and analyzed statistically (t-test and ANOVA). The level of significance was set at p < 0.05. Results. Under tested experimental conditions, the type of canal filling material did not have significant effect on the results of apical extrusion during retreatment. Significantly more material was extruded in the resilon group when manual, Hedstrom file was used (1.80 ? 1.13) than rotary ProTaper (0.60 ? 0.70) and Twisted File (0.50 ? 0.71). Conclusions. The use of a rotary technique is recomended to minimize apical extrusion, especially when resilon obturation material is removed during retreatment.
