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 Background Smear layer is a negative factor which prevents adhesion of the filling material to the dentinal walls. Recent advances in dental research have incorporated lasers as a potential adjunct in root canal treatment by removing the smear layer before filling the root canal system, enhancing the adhesion of sealers to dentin and improving the sealing ability. Aim To evaluate the microtensile bond strength of AH-Plus resin-based sealer to dentin after treatment with 980 nm diode and 1,064 nm neodymium-doped:yttrium aluminum garnet (Nd:YAG) laser in vitro. Materials and methods Thirty specimens prepared for three groups namely group I (control), group II (980 nm diode–lased specimens) and group III (Nd:YAG–lased specimens). One tooth from each group was observed under scanning electron microscope for evaluation of intracanal root dentin morphology. Remaining specimens were used for making microsections by hard tissue microtome. Specimens for groups II and III were lased with 980 nm diode and 1,064 nm Nd:YAG laser. AH Plus sealer was applied onto specimens and mounted onto Instron universal testing machine for microtensile bond strength testing. Results were subjected to statistical analysis using one-way analysis of variance (ANOVA) and Tukey's test. Results Group III Nd:YAG had maximum mean microtensile bond strength values (11.558 ± 0.869), followed by group II diode (9.073 ± 0.468) and group I control (6.05 ± 0.036). Statistically significant differences were seen among all the groups. SEM analysis shows removal of smear layer in both groups II and III. Conclusion Both Nd:YAG and diode laser were more effective than control group in improving the microtensile bond strength of AH Plus sealer to dentin. Clinical significance Lasers have the potential to increase the adhesiveness of root canal sealer to dentin surface, thereby improving the quality of root canal obturation.

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.

Objectives: The aim of this study was to evaluate and compare the push-out bond strength of bioceramic sealer and resin-based sealer on Erbium-doped Yttrium Aluminum Garnet (Er:YAG) treated root canals. Material and Methods: Sixty single-rooted teeth were collected, decoronated apical to the cementoenamel junction, maintaining the minimum root length of 14 mm. Samples were instrumented with WaveOne Gold primary file and divided into two experimental groups (n = 30), based on laser irradiation: Group I: No laser and Group II: Er:YAG laser irradiated. Groups I and II were again divided into two subgroups “a” (AH Plus) and “b” (mineral trioxide aggregate [MTA] Fillapex) with 15 samples in each group. As per the grouping, sealers were coated onto the canal walls and obturated. After 24 h of storage in 100% humidity at 37°C, all the samples were sectioned transversely and push-out test was performed using universal testing machine. Stereomicroscope was used to determine the mode of failure. A one-way analysis of variance was employed to compare the mean POBS. Kolmogorov–Smirnov and Shapiro–Wilk parametric tests were done to check the normality. The Games-Howell multiple post hoc test was used for pairwise comparison of the groups at a 95% confidence level. Results: Both AH Plus and MTA Fillapex exhibited higher bond strength in the laser-treated canals. AH plus exhibited superior bond strength compared to MTA Fillapex in both laser and non-laser-treated groups (P < 0.05). AH Plus groups have predominantly presented cohesive failure whereas MTA Fillapex presented mixed failures. Conclusion: Irradiation with Er:YAG laser in the root canal before obturation improves the bond strength significantly. The adhesive properties of MTA Fillapex are comparable to that of AH Plus.

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.

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.
