“…Then the filling material underwent a dislodging force in the apico-coronal direction at a crosshead speed of 0.5 mm/min using the stainless steel plunger, measuring 0.8 mm in diameter, in a universal testing machine (Hounsfield Test Equipment, Model H5K-s, Surrey, England). The maximum force that dislodged the material was measured in Newton and converted to MPa using the formula below: 19 …”

Background and aims. The single-cone technique has gained some popularity in some European countries. The aim of the present study was to compare the push-out bond strength of gutta-percha to root canal dentin with the single-cone and cold lateral compaction canal obturation techniques.Materials and methods. The root canals of 58 human mandibular premolars were prepared using modified crown-down technique with ProTaper rotary files up to #F3as a master apical file (MAF) and divided randomly into groups A and B based on canal obturation technique. In group A (n = 29) the root canals were obturated with single-cone technique with #F3(30/.09) ProTaper gutta-percha, which was matched with MAF in relation to diameter, taper and manufacturer; in group B (n = 29) the canals were obturated with gutta-percha using cold lateral compaction technique. In both groups AH plus sealer were used. After two weeks of incubation, three 2-mm slices were prepared at a distance of 2 mm from the coronal surface and push-out test was carried out. Data were analyzed with descriptive statistics using independent samples t-test.Results. There were statistically significant differences between two groups. The mean push-out bond strength was higher in group B (lateral compaction technique) compared to group A (single-cone technique; P < 0.05).Conclusion. Use of single-cone technique for obturation of root canals resulted in a lower bond strength compared to cold lateral compaction technique.

“…As compared with AH Plus, Epiphany, and MTA-Fillapex, iRoot SP had the highest dislodgment resistance from the root dentin [ 87 ]. Moreover, the prior placement of intracanal calcium hydroxide improved the bonding of iRoot SP to the root dentin; however, the bonding was less than that of AH Plus and comparable to MTA-Fillapex in the absence of calcium hydroxide [ 88 ]. This improvement in bonding is explained by way of the chemical interaction between calcium hydroxide and the iRoot SP sealer increasing the frictional resistance and/or micromechanical retention of the sealer [ 88 ].…”

Bioceramic-based root canal sealers are considered to be an advantageous technology in endodontics. The aim of this review was to consider laboratory experiments and clinical studies of these sealers. An extensive search of the endodontic literature was made to identify publications related to bioceramic-based root canal sealers. The outcome of laboratory and clinical studies on the biological and physical properties of bioceramic-based sealers along with comparative studies with other sealers was assessed. Several studies were evaluated covering different properties of bioceramic-based sealers including physical properties, biocompatibility, sealing ability, adhesion, solubility, and antibacterial efficacy. Bioceramic-based sealers were found to be biocompatible and comparable to other commercial sealers. The clinical outcomes associated with the use of bioceramic-based root canal sealers are not established in the literature.

“…TAP has been used most often during revascularization procedures to disinfect the root canal system in necrotic immature teeth. [ 15 ] In addition, the paste can also be used traditionally in root canal treatment in infected root canals before root canal obturation with sealer because of its good antimicrobial properties. [ 16 ] Antibiotic pastes can influence the bond strength of the root filings negatively or positively.…”

Aim:To evaluate the effects of calcium hydroxide (CH), triple and double antibiotic pastes (DAPs) on the bond strength of Smart-Seal obturation, C-points with Endosequence Bio-ceramic (BC) sealer to the root canal dentin.Materials and Methods:Sixty-four freshly extracted single-rooted human mandibular premolars were de-coronated and prepared using rotary Pro-taper system with full sequence till F3. The specimens were randomly divided into a control group (without intracanal dressing) and 3 experimental groups that received an intracanal dressing with either CH, DAP, or triple antibiotic paste (TAP) (n = 16). The intracanal dressing was removed after 3 weeks by rinsing with 10 mL 17% ethylenediaminetetraacetic acid, followed by 10 mL 3% sodium hypochlorite. The root canals were then obturated with C-points and Endosequence BC sealer. A push-out test was used to measure the bond strength between the root canal dentin and the obturating system. The data were analyzed using two-way analysis of variance and Tukey post-hoc test.Results:The push-out bond strength values were significantly affected by the intracanal medicaments (P < 0.001), but not by the root canal thirds (P > 0.05). In the middle and apical third, the bond strength of the TAP group was higher than those of the CH and DAP groups (P < 0.05).Conclusions:The DAP and CH did not affect the bond strength of the novel hydrophilic obutrating system. TAP improved the bond strength of Smart-Seal system in the middle and apical thirds.
