“…An ideal endodontic biomaterial should adhere to the cavity walls and resist dislodging forces to help maintain the integrity of the root filling-dentine interface either under static conditions or during function and operative procedures 15,16) . To assess this property in vitro, the push-out test has been shown to be efficient and reliable as the test conditions are comparable with the clinical situation in which the tested materials are placed directly into prepared canals with a natural canal shape and tubule arrangement 16) .…”

The purpose of this study was to evaluate the effects of ultrasonic and manual placement techniques on the push-out bond strength of Biodentine and MTA with and without calcium chloride. One hundred and twenty mid-root slices from forty freshly extracted single-rooted human mandibular premolar teeth were instrumented and randomly divided into six groups (n=20) according to the filling material and placement technique applied, as follows: G1: MTA-manual compaction, G2: Biodentine-manual compaction, G3: MTA+5% CaCl2-manual compaction, G4: MTA-ultrasonic activation, G5: Biodentine-ultrasonic activation, G6: MTA+5% CaCl2-ultrasonic activation. The push-out bond strengths were measured using an Instron testing machine. Data were analyzed using twoway analysis of variance (ANOVA) with Bonferroni correction. The ultrasonic activation significantly enhanced the bond strength values of the materials. Biodentine presented higher bond strength values than that of MTA groups. The addition of CaCl2 to MTA did not improve the bond strength of the material.

“…8,15 In the present study, the push-out test was used because it has become a widely accepted method for recording the interfacial bond strength of endodontic materials to root dentin, even at low levels. 16 It has been shown that the push-out test produces a more homogenous stress distribution and less variability than the microtensile bond test during dislocation resistance testing to intraradicular dentin.…”

Bond strength of a calcium silicatebased sealer tested in bulk or with different main core materials Abstract: The aim of this study was to evaluate the influence of a calcium silicate-based sealer (iRoot SP), with or without a core material, on bond strength to radicular dentin, in comparison with various contemporary root filling systems. Root canals of freshly extracted singlerooted teeth (n = 60) were instrumented using rotary instruments. The roots were randomly assigned to one of the following experimental groups: (1) a calcium silicate-based sealer without a core material (bulk-fill); (2) a calcium silicate-based sealer + gutta-percha; (3) a calcium silicate-based sealer + Resilon; (4) a methacrylate resin-based sealer (RealSeal SE) + Resilon; (5) an epoxy resin-based sealer (AH Plus) + gutta-percha, and (6) a mineral trioxide aggregate-based endodontic sealer (MTA Fillapex) + gutta-percha. Four 1-mm-thick sections were obtained from the coronal aspect of each root (n = 40 slices/group). Push-out bond strength testing was performed at a cross-head speed of 1 mm/min, and the bond strength data were analyzed statistically by one-way analysis of variance and Tukey tests (p < 0.05). The highest and lowest debonding values were obtained for the calcium silicate-based sealer bulk-fill and mineral trioxide aggregate-based endodontic sealer + gutta-percha groups, respectively (p < 0.05). It was concluded that the calcium silicate-based sealer showed higher resistance to dislocation in the bulk-filled form than in conjunction with the tested core filling materials. When the calcium silicate-based sealer was placed in bulk, its dislocation resistance was similar to that of commonly used sealer + core root filling systems. Thus, the concept of using a calcium silicatebased sealer in bulk can be more easily advocated in clinical practice.

The purpose of this study was to compare the apical microleakage in root canal filled with Resilon by several self-etching primers and methacrylate-based root canal sealer. Seventy single-rooted human teeth were used in this study. The canals were instrumented by a crown-down manner with Gate-Glidden drills and .04 Taper Profile to ISO #40. The teeth were randomly divided into four experimental groups of 15 teeth each according to root canal filling material and self-etching primers and two control groups (positive and negative) of 5 teeth each as follows: group 1 -gutta percha and AH26 � sealer; group 2 -Resilon, RealSeal ™ primer and RealSeal ™ sealer; group 3 -Resilon, Clearfil SE Bond � primer and RealSeal ™ sealer group 4 -Resilon, AdheSe � primer and RealSeal ™ sealer. Apical leakage was measured by a maximum length of linear dye penetration of roots sectioned longitudinally by diamond disk. Statistical analysis was performed using the One-way ANOVA followed by Scheffe' s test. There were no statistical differences in the mean apical dye penetration among the groups 2, 3 and 4 of self-etching primers. And group 1, 2 and 3 had also no statistical difference in apical dye penetration. But, there was statistical difference between group 1 and 4 (p < 0.05). The group 1 showed the least dye penetration. According to the results of this study, Resilon with selfetching primer was not sealed root canal better than gutta precha with AH26 � at sealing root canals. And there was no significant difference in apical leakage among the three self-etching primers. [J Kor Acad Cons Dent 33(2):133-140, 2008]
