Purpose: To evaluate the effect of 3% green tea extract (GTE) on wettability, depth of penetration, and push out bond strength (PBS) of AH Plus sealer to intraradicular dentin following the use of 0.2% Nano chitosan or 17% EDTA. Materials and methods: Twenty human radicular dentin segments were used for wettability assessment. Following immersion in 2.6% NaOCl solution, samples were divided into 2 groups (n=10) according to the chelating agent used: group I: 0.2% Nano chitosan, and group II: 17% EDTA, each used for 3 min, then the contact angle (CA) was measured. The samples were further immersed in 3% GTE solution for 5 min followed by CA measurement. Twenty human mandibular premolars were prepared up to # X4 ProTaper Next files, then divided into two groups as mentioned previously. Each group was subdivided into two subgroups based on the final flush used (n=5); subgroups A and B; no treatment, and 3% GTE, respectively. Samples were obturated by cold lateral compaction using AH Plus sealer and gutta-percha. PBS was measured using a universal testing machine and sealer penetration was assessed using confocal laser scanning microscopy. Results: Using 3% GTE following the use of 0.2% Nano chitosan significantly increased the wettability and PBS of AH Plus sealer to intraradicular dentin, while its use following 17% EDTA significantly decreased the wettability and PBS of AH Plus sealer. Using GTE increased the maximum depth of AH Plus sealer penetration into the dentinal tubules. Conclusion: GTE improved the wettability, depth of penetration, and push out bond strength of AH Plus sealer to intraradicular dentin treated with Nano-chitosan. Nevertheless, it adversely affected those properties of AH Plus sealer to EDTA-treated dentin.

“…In addition, AH Plus appeared to contract during setting [ 36 ]. This finding was in accordance with several other studies that evaluated the impact of the presence or absence of a smear layer [ 17 ] or of using different dentin conditioning [ 37 ] and irrigation protocols [ 38 ] on the POBS of BioRoot RCS, which was better than that of AH Plus sealer.…”

Background The aim of this study was to evaluate the effect of thermal and mechanical cyclic aging using a mastication simulator on push-out bond strength of mandibular premolars obturated with AH Plus and BioRoot RCS root canal sealers. Methods With REVO-S files up to SU/0.06 taper, 48 single-rooted premolar teeth were instrumented. The teeth were randomly divided into two main groups (n = 24) based on the two root canal sealers used (AH Plus and BioRoot RCS). All teeth were obturated with h matched-taper single-cone. Each main group was then subdivided into three subgroups (A, B, and C) (n = 8). Group A served as the negative control group (no-thermocycling aging). While groups B and C were subjected to thermal changes in a thermocycler machine (15,000 and 30,000 thermal cycles, respectively), followed by two different dynamic loading periods, 3 × 105 and 6 × 105 in a masticatory simulator with a nominal load of 5 kg at 1.2 Hz which represent roughly 1½ and 3 years of clinical function respectively. 2 mm slice at 3 levels, apical, middle, and coronal, to obtain 3 sections were prepared and subjected to push-out test using a universal testing machine. Statistical analysis was performed using analysis of variance (ANOVA) followed by a Tukey post hoc comparisons test and an independent T-test. A significance level of 5% was used. Results After thermal–mechanical cyclic aging, the two root canal sealers showed a significantly decreased in push-out bond strength (p < 0.05), however, AH Plus had significantly higher bond strength values than BioRoot RCS after cycling aging. Conclusions It could be concluded that thermal–mechanical cyclic aging had a significant impact on the outcome of the dislodgment resistance of AH Plus and BioRoot RCS.

“…Being resin free, it is capable of flowing into the dentinal tubules with no shrinkage and provides excellent adhesion to dentin and gutta-percha and its ability to seal auxiliary canals. [ 15 ] A study done by Dayanand Chole et al . [ 3 ] reported that BioRoot RCS showed the highest bond strength than AH Plus and MTA Fillapex due to its true self-adhesive nature.…”

Effect of nonthermal atmospheric plasma on the push-out bond strength of epoxy resin-based and bioceramic root canal sealers: An in vitro study

et al. 2021

Aim: The aim of this study was to evaluate the effect of nonthermal atmospheric plasma (NTAP) on the bond strength of epoxy resin-based and bioceramic root canal sealers. Materials and Methods: Freshly extracted forty ( n = 40) single-rooted mandibular premolar teeth were divided into four groups ( n = 10) based on the sealer used and NTAP application – Group 1: Epoxy resin-based sealer (AH Plus) without NTAP application, Group 2: Epoxy resin-based sealer (AH Plus) with NTAP application for 30 s, Group 3: Bioceramic sealer (BioRoot RCS) without NTAP application, and Group 4: Bioceramic sealer (BioRoot RCS) with NTAP application for 30 s. After NTAP application in Groups 2 and 4, all the samples were obturated using sealers according to their grouping protocols. Two-millimeter slices were obtained from each sample using hard tissue microtome, which were subjected to push-out bond strength (PBS) under the universal testing machine. Data were subjected to statistical analysis using one-way analysis of variance followed by the Post hoc tukey test. The level of statistical significance was set at P < 0.05. Results: The PBS values were observed to be significantly higher in bioceramic sealer with NTAP application (Group 4) followed by epoxy resin-based sealer with NTAP application (Group 2). Conclusion: NTAP application enhanced the PBS of bioceramic (BioRoot RCS) and epoxy resin-based (AH Plus) sealers compared to their control groups.
