“…With regards to the presence of voids, no differences were found among the three methods for the different sections analyzed. None of the studied methods produced fillings without voids, which is in agreement with another study that used the lateral compaction technique in root canal filling of maxillary incisors (21). The lateral compaction technique presented an increase of the area of the root canal filled in this type of anatomy, but obvious voids and spreader tracts were evident in some cross-sections (Fig.…”

The aim of this study was to evaluate, by stereomicroscopy and confocal laser microscopy, the influence of different lateral compaction methods for the obturation quality, as well as the time spent for the procedure. Thirty root canals of freshly extracted single-rooted human teeth were prepared with the ProTaper system up to F5 instrument and filled with gutta-percha and AH Plus sealer by the lateral compaction technique. The teeth were divided into 3 groups (n=10) in accordance with the method used for the lateral compaction, as follows: Manual, Mechanical and Ultrasonic. The sealers were stained with rhodamine B dye in a proportion of 0.1% per gram in weight to allow for the analysis under a confocal microscope. During the root filling procedure, the time spent was recorded with a stopwatch. The specimens were stored at 37 °C for 48 h, and then sectioned at 2, 4 and 6 mm from the apex. The percentage of gutta-percha, sealer and void areas were evaluated using a stereomicroscope and sealer penetration perimeter by confocal laser microscope. Statistical analyses were performed using the Kruskall-Wallis and Dunn tests (p<0.05). The mechanical method required a shorter time for the lateral compaction than the manual method (p<0.05). There were no significant differences (p>0.05) for the perimeter of the dentin with sealer penetration among all groups. The mechanical method showed a higher (p<0.05) percentage of gutta-percha and less sealer at the 4 mm section in comparison with the manual method. The ultrasonic group showed intermediate values. The void areas found in the root filling were similar (p>0.05) between the three methods. In conclusion, the fastest lateral compaction was achieved with the mechanical method, and all the methods showed void areas in the root filling.

“…Still in reference to the original formulation, Marciano et al 24 (2010) evaluated the apical portion of root canals filled with different obturation systems and sealers (including GuttaFlow), and showed similarity in the percentage of voids between groups. These findings agree with ours, indicating that GuttaFlow offers proper flowability, but it is not superior to other conventional materials.…”

“…In this regard, GuttaFlow presents post-setting expansion 7 and chemical bond with gutta-percha and root canal walls 8 , which could influence the filling of root canal space 24 with high percentage of gutta-percha--filled areas when used in the single-cone technique or with additional accessory gutta-percha cones 25 . The single-cone technique has become increasingly popular, especially in root canals prepared with rotary or reciprocating nickel-titanium systems 12,26 .…”

“…The flowability and longer polymerization time of epoxy resin-based sealers allow them to penetrate deeper into the irregularities, 1,6,8 thus enhancing the mechanical interlocking between the sealer and dentine. 11 However, our results showed a significantly lower dentin bond strength with Sealer 26.…”

“…1,6,7,8 However, the heat required to plasticize GP cones promotes the degradation of its components 9 and alteration of the chemical composition of epoxy-based sealers. 10 The bond strength of the filling material to the radicular dentin is primarily the result of physicochemical interactions across their interface.…”

The aim of this study was to evaluate the effects of different root canal filling techniques on the bond strength of epoxy resin-based sealers. Sixty single-rooted canines were prepared using ProTaper (F5) and divided into the following groups based on the root filling technique: Lateral Compaction (LC), Single Cone (SC), and Tagger Hybrid Technique (THT). The following subgroups (n = 10) were also created based on sealer material used: AH Plus and Sealer 26. Two-millimeter-thick slices were cut from all the root thirds and subjected to push-out test. Data (MPa) was analyzed using ANOVA and Tukey's test (α = 0.05). The push-out values were significantly affected by the sealer, filling technique, and root third (p < 0.05). AH Plus (1.37 ± 1.04) exhibited higher values than Sealer 26 (0.92 ± 0.51), while LC (1.80 ± 0.98) showed greater bond strength than THT (1.16 ± 0.50) and SC (0.92 ± 0.25). The cervical (1.45 ± 1.14) third exhibited higher bond strength, followed by the middle (1.20 ± 0.72) and apical (0.78 ± 0.33) thirds. AH Plus/LC (2.26 ± 1.15) exhibited the highest bond strength values, followed by AH Plus/THT (1.32 ± 0.61), Sealer 26/LC (1.34 ± 0.42), and Sealer 26/THT (1.00 ± 0.27). The lowest values were obtained with AH Plus/SC and Sealer 26/SC. Thus, it can be concluded that the filling technique affects the bond strength of sealers. LC was associated with higher bond strength between the material and intraradicular dentine than THT and SC techniques.
