“…Also, some ingredients of AH Plus, such as silicone oils, can affect the sealing ability of this material. 19 AH Plus being oil based material could prevent complete wetting of the root canal wall and adhere poorly to humid dentine, 26 so canal must be dry before placement of sealer. The most advantageous and more predictable results are obtained if the root canal system is as dry as possible before obturation.…”

Abstract:Objective: This study was designed to compare the level of apical microleakage of root canal sealers; Acroseal, AH Plus, Endoflas FS and Endomethasone N, with laterally condensed gutta percha by level of apical dye penetration. Materials and Methods: Freshly extracted sixty permanent maxillary anterior teeth were divided randomly into four groups. Shaping and cleaning of teeth was done followed by obturation with gutta percha and four different root canal sealers. Samples were immersed in 2% methylene blue dye solution in individual dappen dish and stored in the solution for 30 days. The roots were split longitudinally with a chisel in two halves and observed under stereomicroscope. Apical microleakage measured from the apex to the most coronal extent of dye penetration. Results: Minimum microleakage was observed with AH Plus with mean value 2.140 mm, standard deviation 0.817. The maximum microleakage was observed with Endomethasone N with mean value 3.858 mm, standard deviation 1.840. There was no statistically significant difference in microleakage between Acroseal, AH Plus, and Endoflas FS. Endomethasone N showed highest level of microleakage than other three groups under the test condition, which was statistically significant. Conclusion: The microleakage was the lowest for the AH Plus and increased in the following order, Endoflas FS, Acroseal, Endomethasone N.

Introduction: To achieve success in endodontic treatment, the root canal system should be as sealed as possible with suitable material such as gutta-percha and sealer. Objective: This study compare the apical leakage of roots obturated with GuttaCore™, lateral condensation, and continuous wave obturation through a computerized fluid-transport system. Material and methods: Fiftytwo freshly extracted upper molars were used. The disto-buccal roots were cut and standardized to 10 mm long. The root canals were prepared at working length with WaveOne primary reciprocating files. The specimens were randomly divided and filled by one of the following obturation techniques: GuttaCore™, lateral condensation or continuous wave obturation, using SILCO sealer. The positive controls were left unfilled and the negative controls were totally coated with cyanoacrylate and three layers of nail polish. The roots were stored in relative humidity for 72 h at 37°C, allowing the sealer to set. After this period, the roots were connected to a computerized fluidtransport system, and the apical leakage was analyzed. Results: The results were expressed in µL.cmH2O-1.min-1 x10-4 1.36 atm. The data were statistically analyzed using one-way ANOVA and Tukey´s tests. The specimens of the positive control group showed extreme amounts of apical leakage. There was no leakage in the negative

“…Apical microleakage was measured using a computerized fluid filtration meter, as described by Orucoglu et al 16 The roots were inserted into the plastic tube from the apical side and were connected to 18-gauge stainless steel tubes. A cyanoacrylate adhesive (Zapit, Dental Venture of America Inc., Anaheim Hills, CA, USA) was applied circumferentially between the roots and plastic tubes.…”

“…The computerized fluid filtration meter with laser system used in this study had a 25-µl micropipette (Microcaps, Fisher Scientific, Philadelphia, PA, USA) mounted horizontally. 16 O 2 from a pressure tank of 120 kPa (1.2 atm) was applied on the apical side. The pressure was kept constant throughout the experiment by means of a digital air pressure regulator added to the pressure tank.…”

Objectives: This study aimed to evaluate the apical seal obtained with lateral compaction of gutta-percha in oval-shaped root canals prepared with either self-adjusting files or ProTaper Universal rotary files. Materials and Methods: Twelve pairs of extracted mandibular premolars with oval-shaped root canals were randomly divided into two groups. The first group was biomechanically prepared with ProTaper Universal files, while the self-adjusting file system was used in the second group. The roots were better filled using cold lateral compaction of gutta-percha. Apical microleakage was measured with the computerized fluid filtration method. The results were analyzed statistically using the Mann-Whitney U test. Results: All of the roots in both groups showed leakage. Group 1 demonstrated significantly less microleakage (p<0.05). Conclusions: Instrumentation of oval-shaped canals using a self-adjusting file system with cold lateral compaction of gutta-percha demonstrated significantly greater apical microleakage when compared to ProTaper Universal. The apical leakage with different filling techniques, combined with self-adjusting files, should be evaluated in further studies.
