“…4 In view of these characteristics, AH Plus is currently regarded as the clinical reference standard endodontic sealer. 5 Calcium silicate-based bioactive sealers, such as Total Fill BC Sealer and Sure Seal Root sealer, are becoming more popular due to their improved mechanical, chemical and cytocompatible properties. 6 They are reported to be insoluble, premixed and hydrophilic, which could minimize the risk of void formation in the root canal sealers, and might even benefit from the pre-existing moisture in the root canals during their final setting.…”

Bioactive sealers showed higher root filling rate, lower incidence rate of voids, void fraction and void volume than AH Plus under nano-CT analysis, when round root canals were treated by the single cone technique. The disparate results suggest that the higher resolution of nano-CT have a greater ability of distinguishing internal porosity, and therefore suggesting the potential use of nano-CT in quantitative analysis of filling quality of sealers.

“…The computerized fluid filtration technique which has a digital air pressure arrangement and computerized control is an upgraded model of conventional fluid filtration technique, this upgraded model was used to evaluate apical leakage in many studies. [ 17 18 19 ] Computerized fluid filtrate method has some advantages over conventional leakage tests; so that, the samples are not affected from the test procedures, the measurements can be repeated.…”

Objectives:To evaluate the effect of spreader size on apical leakage of maxillary incisor teeth.Materials and Methods:A total of 75 permanent human teeth with no carious and no fracture or crack were used for this study. After removing the crown from the cementoenamel junction and the standardization of the root lengths, the specimens were randomly divided into five groups: Group 1 - Roots were not instrumented. Group 2 - Root canals were enlarged using the step-back technique to a #40 file and filled using cold lateral compaction (CLC) of gutta-percha (GP). Group 3 - During the filling procedure, the first spreader used was size 40. Group 4 - The first spreader used was size 35. Group 5 - The initial spreader used was size 25. The amount of leakage through the filled root canals was evaluated by computerized fluid filtration model. Statistical analyzes were done using Kruskal–Wallis test and Mann–Whitney test (P < 0.05).Results:There were statistically significant differences among the groups (P < 0.05). While the uninstrumented group (Group 1) had no leakage, instrumented but not filled roots (Group 2) demonstrated the highest leakage values. There were no differences between Group 3 and 4. Group 5 showed significantly less leakage than Group 3 and 4.Conclusion:Spreader size used during CLC of GP appeared to be a significant factor on apical leakage of roots. Using smaller size spreader during CLC may provide relatively less leakage.

Aim and Objectives:The aim of this study is to evaluate and compare the fracture resistance of root canals obturated with four different obturating systems in endodontically treated teeth.Materials and Methods:One hundred and twenty single-rooted teeth were selected and decoronated at cementoenamel junction. Instrumentation of teeth (except control group) was done with Mtwo rotary files up to size 25/0.06 using a step-back technique. All teeth were divided into four experimental groups (n = 25) and two control groups (n = 10). In Group I (negative control), teeth were neither instrumented nor obturated, in Group II (positive control), instrumentation was done, but no obturation was performed, in Group III, obturation was done with cold lateral compaction technique, in Group IV, obturation was done with cold free-flow compaction technique, in Group V, obturation was done with warm vertical compaction technique, and in Group VI, obturation was done with injection-molded thermoplasticized technique. All prepared teeth were embedded in an acrylic resin block, and their fracture strength was measured using Universal Testing Machine. Statistical data were analyzed using one-way analysis of variance and Tukey's honestly significant difference test.Results:Negative control Group I showed highest fracture resistance and positive control Group II had lowest fracture resistance. Among experimental groups, cold free-flow compaction technique with GuttaFlow2 (Group IV) showed higher fracture resistance as compared to the Group III, Group V, and Group VI.Conclusion:GuttaFlow2 has the potential to strengthen the endodontically treated roots to a level that is similar to that of intact teeth.
