The purpose of this study was to evaluate and compare the densities of four different brands of root canal sealers using three different intraoral imaging receptors. Four different root canal sealers used were – AH Plus (Dentsply Germany, Resin based), Epiphany (Pentron USA, Resin based), U/P (Sultan Healthcare, Zinc oxide eugenol based) and Apexit (Ivoclar / Vivadent, Calcium hydroxide based). The sealers were mixed according to manufacturer instructions and six specimens of each material were fabricated. All the specimens were imaged using three different intraoral #2 sized imaging receptors-D and E speed film and storage phosphor plates. D and E speed films were digitized and stored in JPEG format. All the images were exported into the Image J software (rsb.info.nih.gov/ij/) and the mean grey values and integrated density of each material was calculated from four random areas of each image and averaged. Mixed model ANOVA was performed. Pair wise comparison of mean grey values between the three imaging receptors and integral densities recorded by the receptors showed high statistical significance for all the four different root canal sealers. Results showed that the four different types of root canal sealers showed different optical densities on all the three receptors. The purpose of this study is to evaluate and compare the optical densities of four different brands of root canal sealers using three different intraoral imaging receptors.

The purpose of this study was to compare the penetration ability of calcium silicate root canal sealers and conventional resin-based sealer using confocal laser scanning microscopy (CLSM). A total of 60 recently extracted single-rooted human premolars were used in this study. The root canals were prepared to a size 40/0.06 taper with ProFile rotary instruments and irrigated with NaOCl and EDTA. After drying all canals, the specimens were randomly divided into three experimental groups (n = 20): Group 1, gutta-percha (GP)/AH Plus with continuous wave compaction; group 2, GP/BioRoot RCS with a single-cone technique; and group 3, GP/Endoseal MTA with a single-cone technique. All experimental samples were sectioned perpendicular to their long axis using a low-speed diamond wheel at the apical, middle, and coronal third levels. The penetration abilities of all samples were evaluated using CLSM. A Kruskal–Wallis analysis and a series of Mann–Whitney U post hoc tests were performed. A higher intensity level was found in the coronal area and a lower intensity level in the apical area in all the experimental groups. The AH Plus group showed higher sum fluorescence intensity in the apical and coronal thirds compared with the BioRoot RCS and Endoseal MTA groups, whereas the BioRoot RCS group showed a higher intensity level in the middle third, similar to the AH Plus group. The maximum sealer penetration depth was low in the apical area and high in the coronal area in the AH Plus and Endoseal MTA groups. In the BioRoot RCS group, maximum sealer penetration was observed in the middle third. In conclusion, there were significant differences in sealer penetration pattern and distance according to the root level and sealer type.

The purpose of this study was to compare the cytotoxic effects and mineralization activity of three calcium silicate-based root canal sealers to those of a conventional resin-based sealer. Experiments were performed using human dental pulp stem cells grown in a monolayer culture. The root canal sealers tested in this study were EndoSequence BC Sealer (Brasseler), BioRoot RCS (Septodont), Endoseal MTA (Maruchi), and AH Plus (Dentsply DeTrey). Experimental disks 6 mm in diameter and 3 mm in height were made and stored in a 100% humidity chamber at 37 °C for 72 h to achieve setting. The cytotoxicity of various root canal sealers was evaluated using a methyl-thiazoldiphenyl-tetrazolium (MTT) assay. To evaluate cell migration ability, a scratch wound healing method was used, and images of the scratch area were taken using a phase-contrast microscope. Cell morphology was evaluated by a scanning electron microscope after direct exposure for 72 h to each sealer disk. In the cell viability assay, there were no significant differences between the EndoSequence BC, BioRoot RCS, Endoseal MTA, and control groups in any experimental period (p > 0.05). In the cell migration assay, there were no significant differences between the EndoSequence BC, Endoseal MTA, and control groups in any experimental period (p > 0.05). BioRoot RCS exhibited slower cell migration relative to EndoSequence BC and Endoseal MTA for up to 72 h (p < 0.05). Conversely, it showed a similar wound healing percentage at 96 h (p > 0.05). In an evaluation of cell morphology, cells in direct contact with EndoSequence BC, BioRoot RCS, and Endoseal MTA disks showed superior spreading compared to those in contact with the AH Plus disk. In an Alizarin red staining assay, EndoSequence BC, BioRoot RCS, and Endoseal MTA showed a significant increase in mineralized nodule formation compared to the AH Plus group (p < 0.05). In conclusion, all calcium silicate-based root canal sealers tested in this study showed good biological properties and mineralization activity compared to conventional resin-based sealer.

Abstract Aim The purpose of this in vitro study was to analyze the antimicrobial activity of root canal sealers by using the agar diffusion test (ADT). Methods and Materials Three categories of root canal sealers were included in the study: resin-based sealers (4), zinc oxide-based sealers (3), and calcium hydroxide-based sealers (2). The microbial strains used were: S. aureus (2 strains), C. albicans (2 strains), and E. faecalis (1 strain). Statistical analysis was conducted using a one-way analysis of variance (ANOVA). Tests of differences were analyzed using the Tukey's test with a value of p < 0.05 considered statistically significant. Results The antimicrobial activity of root canal sealers was ranked in descending order as follows: Sealite Regular, Cortisemol, Dentalis KEZ, AH26, Sealapex, Acroseal/Topseal, and Endorez/AH plus. Conclusion Root canal sealers showed different inhibitory effects depending on their types and the bacterial strains tested. Root canal sealers containing formaldehyde and eugenol proved to be effective against the microorganisms studied. Clinical Significance The incorporation of antimicrobial components into root canal sealers may become an essential factor in preventing the re-growth of residual bacteria and control of bacteria re-entry into the root canal system.

ABSTRACTIntroduction: The aim of this in vitro study was to assess the pH values of selected calcium-silicate root canal sealers in comparison with AH Plus resin-based root canal sealer.Materials and methods: Six root canal sealers were included in this study: BioRoot RCS (Septodont, France), GuttaFlow bioseal (Coltėne/Whaledent, Switzerland), MTA Fillapex (Angelus, Brazil), Total Fill BC Sealer (FKG, Switzerland), Well-Root ST (Vericom, Korea) and AH Plus (Dentsply, DeTrey, Germany). Materials samples (n = 6) were placed in dishes and immersed in 10 mL of distilled water (pH = 6.8). After 1, 3, 24, 48, 72, 168, 336 and 504 hrs, water pH was determined with a pH meter calibrated with a solution of known pH. Data were statistically analyzed using Student-t test (p < 0.05).Results: There were differences in the water pH between the materials tested. The highest water pHs were exhibited by Total Fill BC Sealer, Well-Root ST and BioRoot RCS (pH ~12), followed by GuttaFlow bioseal (pH ~10.5) and MTA Fillapex (pH ~9). The lowest pH was shown by AH Plus (pH ~8).Conclusions: All calcium-silicate root canal sealers studied are able to elevate the pH level, which could have biological and antimicrobial effects. The AH Plus root canal sealer has poor alkalizing properties.

Aim: The aim of this study was to evaluate and compare the setting times (ST), flow (FW), radiopacity (RP), dimensional stability (DS), solubility (SB), and polymerization stress (PS) of the MTA Fillapex and AH Plus root canal sealers. Methods: The above qualities were tested according to ISO 6876/2001 standardization. The water used in the dimensional stability test was evaluated to verify the presence of released materials. For the photoelastic analysis, 20 photoelastic resin rings were prepared, and the root canal sealers were inserted. After 24 hours, the specimens were analyzed in a Polariscope. Data of the setting times, flow tests, radiopacity, dimensional stability, and solubility tests were submitted to a Kolgomorov–Smirnov test and then to a Student’s t-test at the 5% significance level. Results: The data derived from photoelastic analyses were submitted to an ANOVA and Tukey’s test with a significance level of 5%. MTA Fillapex and AH Plus complied with ISO 6876/2001. However, there were significant differences (p < 0.05) between the two cements for ST, FW, RP, DS, and SB. MTA Fillapex showed higher FW, SB, and PS when compared with AH Plus. Conclusions: MTA Fillapex and AH Plus complied with ISO 6876/2001 in terms of ST, FW, RP, DS, and SB. MTA Fillapex showed higher PS when compared to AH Plus.

Abstract This study investigated the bond strength of two experimental root canal sealers based on MTA and butyl ethylene glycol disalicylate: MTAe and MTAe-HA. The reference materials used for comparison were AH Plus and MTA Fillapex. Twenty human upper incisors were selected and one 1 mm slice was obtained from the cervical third of each root. On the coronal surface of each slice, four 0.9 mm wide holes were drilled through the dentine. Standardized irrigation was performed and holes were filled with one of the four tested sealers: AH Plus, MTA Fillapex, MTAe, and MTAe-HA. The filled slices were stored in a PBS solution (pH 7.2) for 7 days at 37 °C. A push-out assessment was performed with a 0.7 mm plunger tip. Load was applied at a crosshead speed of 0.5 mm/min until sealer displacement. The results were expressed in MPa. The Kruskal-Wallis test was applied to assess the effect of each sealer on the push-out bond strength. Mann-Whitney with Bonferroni correction was used to isolate the differences. The alpha-type error was set at 0.05. Significant differences among medians values obtained by materials were observed (p<0.001). AH Plus displayed the highest value of bond strength (p<0.001). In contrast, MTA Fillapex presented the lowest bond strength among all tested sealers (p<0.001). Experimental sealers showed intermediary bond strength values, with no statistical differences between them (p>0.05). In conclusion, experimental root canal sealers presented suitable bond strength outcomes when compared to MTA Fillapex.

ABSTRACT Objective: The objective was to evaluate the subcutaneous biocompatibility of two root canal sealers. Materials and Methods: Thirty female rats were distributed into two groups of 15 animals. Each received subcutaneous dorsal implants: Silicone tubes filled with AH Plus or Obtuseal. After the 11th, 14th, and 45th days, tissues were collected for biopsy and fixed and processed for histologic evaluation. Observations of the cellular inflammatory components, such as lymphocytes and macrophages, were made. The data were analyzed using Kruskal–Wallis and Connover tests (P < 0.05). Results: By the 7th day, lymphocyte infiltration increased in both groups (P = 0.0104). However, macrophage infiltration increased only in the AH Plus group (P = 0.0011). By the 14th and 45th days, lymphocyte and macrophage infiltrations were reduced. At the end of the experimental period, no statistically significant differences were found between the AH Plus group and the Obtuseal group (P > 0.05). Conclusion: After 45 days, Obtuseal yielded a satisfactory tissue reaction; it was biocompatible when tested in subcutaneous rat tissue. On the basis of the obtained results, it was concluded that Obtuseal root canal sealer caused a satisfactory tissue reaction as AH plus, because it was biocompatible when tested in the subcutaneous tissue of rats.
