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.

Root Canal Sealers

The aim of this study was to evaluate ex vivo the sealing achieved at simulated lateral canals (SLC) and the quality of filling according to their position in the root canal after using the same filling technique. SLC were created at three levels in 55 teeth and divided into two groups depending on the root canal sealer used (1: BioRoot® RCS, 2: GuttaFlow® bioseal). They filled them with the continuous wave technique and submitted to a diaphanization technique. The samples were analyzed using a magnifying lens (20×), pictures were taken, which proceeded to linear measurement with the ImageJ® program and used a filling score system with five grades (0 to 4, 0 and 1 not acceptable, 2 to 4 acceptable); BioRoot® RCS has got a greater proportion than GuttaFlow® bioseal for SLC filled acceptably at 10 mm from the apex (p < 0.05). The highest proportion of SLC filled acceptably was found in the middle third (6 mm) (p < 0.05), followed by the apical third (3 mm) and the coronal third (10 mm). The difference between apical and coronal third could be significant; BioRoot® RCS has been better than GuttaFlow® bioseal for filling SLC in the coronal third of the teeth. Studies on the characteristics of these cements are missing to explain these differences.

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.

Apical Leakage

An in vitro study was conducted to compare gutta-percha obturation techniques of the developing incisors in dogs. Two perpendicular radiographic views were used for evaluation of apical and overall appearance of root canal obturation. Apical leakage technique was used to evaluate ability of each method to provide adequate apical obturation. The endodontic technique utilizing warm vertical condensation with chemically softened guttapercha in the apical region provided the best radiographic appearance without apical dye leakage. The same vertical obturation technique without the use of chemically softened gutta-percha in the apical region showed 33% dye leakage incidence. Lateral obturation techniques provided the least qualitative radiographic appearance to the endodontic fill and dye leakage incidence. Results of evaluation of quality of apical obturation of root canals based on X-ray examination and apical dye leakage resulted in the following conclusions: lateral obturation techniques used in this study have their limitations resulting from typical root canal anatomy; vertical obturation techniques showed better hermetic apical sealing, mainly in the case of vertical condensation of the chemically softened gutta-percha in the apical part of the root canal.

Introduction Root canal filling materials are intended to prevent microleakage and passing of microorganisms and their toxins along the root canal space and into the periradicular tissues. Objective Objective of this in vitro study was to evaluate and compare apical leakage of root canals obturated using a modified warm vertical condensation technique and different materials. Methods Sixty-five extracted single-root teeth were prepared according to the crown-down/ step-back technique. Each canal was rinsed with 3% NaOCl during and after the preparation. The teeth were divided into 3 groups. Every group was obturated by the same technique, but with different materials: RealSeal system (SybronEndo), gutta-percha with AH Plus (Dentsply Maillefer) and gutta-percha with Acroseal sealer (Septodont). The remaining 20 teeth were in the control group. The teeth were immersed in 1% methylene blue for 72 hours. After that period, the roots were split longitudinally, and dye penetration was measured using a stereomicroscope. Results Dye penetration occurred in all groups. The least dye penetration occurred in the RealSeal group (0.33?}0.29 mm), while the highest dye penetration occurred in the Acroseal group (1.11?}0.52 mm). According to the Student's t-test, Acroseal showed significantly more leakage (p<0.001) than RealSeal and AH Plus materials. The microleakage of RealSeal system was not significantly different (p>0.05) from that of AH Plus sealer with gutta-percha. Conclusion The results suggested that new material Resilon (RealSeal) and conventional combination AH Plus with gutta-percha had the least apical dye penetration and provided the best sealing.

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.

Microleakage can result in failure of endodontic treatment. An important characteristic of endodontic sealer is sealing ability. The aim of this experimental study was to compare the apical leakage of teeth obturated with single-cone and warm vertical condensation techniques using three different sealers (Cortisomol, AH Plus, Apexit Plus). Materials and Methods: Sixty extracted human lower premolar teeth were selected and randomly assigned to six groups (n = 10), according to the root canal sealer and technique used for obturation: (A) Single-cone technique with Cortisomol; (B) Single-cone technique with AH Plus; (C) Single-cone technique with Apexit Plus; (D) Warm vertical condensation technique with Cortisomol; (E) Warm vertical condensation technique with AH Plus; (F) Warm vertical condensation technique with Apexit Plus. 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: The mean penetration length of dye in Cortisomol, AH Plus and Apexit Plus samples were 0.85, 0.98 and 0.58 mm, respectively. The differences between three groups were not significant (p > 0.05); also, the mean dye penetration in obturating with single-cone and warm vertical condensation techniques using Cortisomol, AH Plus, Apexit Plus was not significantly different. Conclusion: Cortisomol, AH Plus, Apexit Plus were similarly effective in prevention of apical microleakage. Differences in the mean dye penetration between the groups which were obturated with Single-cone and warm vertical condensation were not statistically significant. Key words: Microleakage, single-cone, warm vertical condensation, Cortisomol, AH Plus, Apexit Plus

Aim: To evaluate the effect of irrigation techniques, i.e. different types of irrigation needles, on the quality of cleaning of root canal walls using scanning electron microscopy (SEM). Material and Method: The study was conducted on 16 extracted, single-rooted, human teeth. The samples were allocated to two experimental groups depending on the type of the irrigation needle. Conventional needles were used for the irrigation of Group I and laterally perforated ones for Group II. All root canals were instrumented using K files and the Step-back technique. During instrumentation, all samples were irrigated with 2.5 % sodium hypochlorite solution followed by final irrigation with 17 % EDTA for 1 min. After that, all samples were irrigated with 10 ml of distilled water. The roots were, then, sectioned longitudinally and middle one third of each root canal was analyzed using SEM. Quantitative analysis was based on criteria by H?lsmann et al. Results: The obtained results showed that the more efficient removal of debris and the smear layer was accomplished in the group of samples irrigated using laterally perforated needles than conventional needles. The difference between the investigated irrigation techniques were statistically significant (p<0.01). Conclusion: The use of laterally perforated needles for irrigation allows more efficient cleaning of root canal walls, i.e. the removal of debris and the smear layer.
