Introduction: Endodontic treatment includes different phases like controlling the growth of microorganism, thorough cleaning and shaping and fluid-tight seal. Sealer plays an important role in Root Canal Treatment (RCT). Sealer fills the space between filling material and dentin. Sealer also acts as a lubricant. Sealer has ability to fill the spaces and prevent microleakege from the root canal. Mineral Trioxide Aggregate (MTA) is a calcium silicate based sealer which has high radiopacity, low solubility and good antibacterial activity. Aim: To evaluate push-out bond strength of MTA as a root canal sealer. Materials and Methods: Studies which were published in English, studies with different years of publication were included. Studies which includes bond strength of MTA as Endodontic Sealer to dentinal wall were also included. Studies used in this review were in-vitro studies and clinical trials. Studies showing tissue toxicity, biocompatibility of MTA were excluded. Also, case reports and in-vivo studies were excluded. All abstracts as well as full texts were studied. PubMed/Medline, Web of Science and Scopus were used for this study. Keywords used were “root canal sealer”, “push-out bond strength”, “MTA”. Total 18 articles were collected. But only five articles fulfilled the inclusion and exclusion criteria. So only five articles were included in this study and discussed in detail. Results: According to the results, of articles which were chosen for this study stated that MTA can be used as an endodontic sealer though it shows lesser push-out bond strength when compared with different newer sealers. Conclusion: In this systematic review, only one in-vitro study showed that Proroot MTA used as root canal sealer exhibits high push-out bond strength than other sealers like MTA Fillapex sealer and AH plus sealer. While MTA Fillapex show lesser push-out bond strength in comparison with other sealers like Proroot MTA sealer, AH plus, Endo CPM sealer. So this systematic review partially fulfills the hypothesis as it gives a utility of Proroot MTA as a root canal sealer.

Objective: The aim of this study was to assess the micro-push-out bond strength of a mineral-based root canal sealer, BioRoot RCS in canals prepared by K3XF rotary systems of two different tapers. Material and Methods: Eighty caries free maxillary central incisors were used in this study. The samples were allocated into 4 groups (n=20) according to the root canal sealer and taper of the rotary instruments. The samples were obturated using single cone obturation technique. From each root 1mm thick slices at coronal, middle and apical thirds were collected using hard tissue microtome under continuous water coolant. Push-out tests were done for these sections using a Universal testing machine (INSTRON 8801) at a crosshead speed of 1mm/min. One-way analysis of variance (ANOVA) was used to compare the bond strengths within groups and Tukey’s multiple post hoc analysis was used for pair-wise comparison of bond strengths. Results: AH Plus exhibited higher micro-push-out bond strength than BioRootRCS though they did not differ significantly (p>0.05). Preparation of root canals with 6% taper rotary instruments showed higher bond strength than 4% though they did not differ significantly (p>0.05). Conclusion: There was no significant difference between micro-push-out bond strength values of BioRoot RCS and AH Plus. The bond strength values were high in 6% taper canals than 4% canals though the difference was not significant statistically.

Abstract The influence of root canal filling techniques on the penetration of AH Plus into dentinal tubules was evaluated using confocal laser scanning microscopy (CLSM) and the impact on the bond strength of the filling material on the root dentin was evaluated using the push-out test. Roots of the maxillary central incisors (n=40) were prepared with ProTaper Universal and assigned to four groups: lateral condensation, vertical compaction, modified Tagger hybrid and single cone. After root canal filling with gutta-percha and AH Plus, along with the addition of 0.01% fluorescein, the roots were cut into 2-mm slices. CLSM was performed on the first slice of each root third, followed by the push-out test. The second slice was analyzed under SEM. ANOVA demonstrated a statistically significant difference between the root canal filling techniques and the root thirds (p<0.05). For percent penetration, Tukey’s test showed that the vertical compaction (91.77±13.51), lateral condensation (89.18±10.91) and modified Tagger hybrid (87.53±15.42) presented the highest values, which significantly differed (p<0.05) from those of the single cone (78.19±22.46). For bond strength (MPa), lateral condensation (3.42±0.54) and vertical compaction (3.47±0.53) had the highest values (p<0.05), while the modified Tagger hybrid (2.19±0.41) and single cone (0.54±0.21) had the lowest. In conclusion, the lateral condensation, vertical compaction and Modified Tagger’s hybrid techniques resulted in greater penetration and bond strength to the intra-radicular dentin.

ABSTRACT Objectives The aim of this study was to compare and evaluate the effect of calcium hydroxide [Ca(OH)2], 2% chlorhexidine (CHX) gel, and propolis when used as intracanal medicaments on the bond strength of a resin-based sealer (AH Plus Jet; Dentsply DeTrey, Konstanz, Germany) to the root dentin. Materials and methods Sixty freshly extracted single-rooted human teeth were utilized for this study and the crowns were decoronated. The root canals were instrumented and randomized into four groups according to the medicament used: Group I: Control; group II: Ca(OH)2; group III: CHX; group IV: Propolis. The specimens were stored for 10 days in 100% humidity at 37°C, and the intracanal dressings were removed by rinsing with 10 mL of 17% ethylenediaminetetraacetic acid followed by 10 mL of 2.5% sodium hypochlorite, then obturated with gutta-percha and AH Plus Jet sealer. A push-out test to measure the bond strength between the root canal dentin and the sealer was done. Two-way analysis of variance and Tukey’s post hoc pairwise tests were used for statistical analysis. Results The use of intracanal medicaments had shown to significantly influence the push-out bond strengths of the resin sealer used (p < 0.05). At coronal and middle thirds, there was no significant difference in bond strengths among all the four groups (p > 0.05). At apical third, the mean bond strength value for propolis group was significantly superior when compared with the other three groups (p < 0.05). The CHX group showed higher bond strength values at apical third compared with Ca(OH)2 and control groups, but it was not significant (p > 0.05). Conclusion Propolis showed superior push-out bond strength than CHX, Ca(OH)2, and control groups at apical third, while no significant differences were observed among all the groups at coronal and middle thirds.

ABSTRACT Introduction: The aim of this in vitro study was to evaluate the bond strength of Photo-Activated Disinfection (PAD) system to dentin with different root canal sealers by using a push-out test design. Materials and Methods: A total of 30 extracted mandibular premolar teeth with single and straight roots were used. The crowns were removed and the root canals were prepared by using ProTaper rotary files. The smear layer was removed and the roots were randomly divided into two groups (n = 15) according to the use of PAD system as the final disinfecting agent. Each group was then divided into 6 (n = 5) subgroups and obturated with gutta-percha and 3 different root canal sealers. The groups were Group 1: Sodium hypochlorite (NaOCl) + ethylenediaminetetraacetic acid (EDTA)-AH Plus sealer; Group 2: NaOCl + EDTA + PAD-AH Plus; Group 3: NaOCl + EDTA-Sealapex; Group 4: NaOCl + EDTA + PAD-Sealapex; Group 5: NaOCl + EDTA-mineral trioxide aggregate (MTA)-Fiallapex; and Group 6: NaOCl + EDTA + PAD-MTA-Fillapex. 1-mm thickness horizontal sections (n: 5 × 4 = 20) were sliced for the push-out bond strength measurement. Results: Group 3 and 4 showed significantly lower bond strengths compared with all the other groups (P < 0.05). No statistically significant difference was found among Groups 1, 2 and 5, but there was statistically significant difference between Group 5 and 6 (P < 0.05). Conclusion: This in vitro study indicated that the PAD system adversely affected the bond strength of the MTA Fillapex root canal sealer.

Aim: To evaluate the impact of environmental pH on intra-radicular dentin push-out bond strengths of MTA, MTA HP, and Biodentine. Materials and Methodology: Freshly extracted human mandibular single-rooted premolars or maxillary anterior incisors that were either intact or contained only small carious lesions were selected.120 mid root dentins is horizontally divided into 1.0 mm thick slices and divided into 3 MTA, MTA HP, BIODENTINE groups. The compressive load is applied at a speed of 0.5 mm/min by exerting a downward pressure on the outer surface of MTA using a 1.00 mm diameter cylindrical stainless-steel plunger. Maximum load to MTA was reported in newtons at the time of dislodgement and converted to megapascals. The 1-way analysis of variance test was used to compare the push-out bond strength of the groups with the same storage time (4 or 34 days), followed by the pair-wise comparison of the Tukey post hoc test. The Student's t-test was used to evaluate 3-group means. At P = .005, the degree of significance was set. Thus the clinical importance of the present study states that considering several factors like microhardness, composition by products, particle sizes and the environmental pH plays a critical role in selection of root end filling material. Results: There was significant difference between groups (P = .001) after 4 days of PBS and Acid condition, where Bio dentine had significantly the highest bond strength. Conclusion: The strength of MTA HP, BIODENTINE, MTA materials at dentine interface increases over 30 days in the storage of PBS solution at pH 7.4, after an initial acid challenge by acetic acid of pH 5.4, which decreases initial bond strength.
