“…Tubliseal EWT showed the highest PSCP value, and the Single cone technique showed the higher PSCP value than the lateral and vertical condensation technique at 3 mm and 6 mm sections. 10 M K Wu et al observed sealer distribution in root canals filled by different root filling techniques. AH26 (0.05 mL) dyed with carbon black powder was placed into the prepared root canals of maxillary central incisors using a lentulospiral.…”

Background:The strength of endodontically treated teeth depends on the remaining amount of tooth structure after canal preparation. Epoxy resin sealers like AH Plus was found to bond better to the core obturation material and root dentine. Hence, the present study was conducted with the aim of assessing the efficacy of root canal sealers in obturated root canals. Materials & methods:A total of 30 freshly extracted mandibular first premolars were collected and enrolled. Decoronation of all the specimens was done. Random division of all the samples was done in three study groups with ten specimens in each group as follows: Group 1: AH Plus sealer, Group 2: Tubliseal sealer, and Group 3: FUJI -1 sealer. Obturation was carried out using the single-cone technique. Stereoscopic examination of the internal aspects of the sealer coated canals was done, followed by a calculation of the total percentage of the sealer-coated perimeter of the canal.Results: Mean percentage of the sealer coated perimeter of the canal among group 1 specimens, group 2 specimens and group 3 specimens was 95.45%, 98.28% and 91.11%, respectively. While analyzing statistically, it was seen that the highest percentage of sealer coated perimeter was found to be of Tubliseal and lowest for FUJI-1, the results of which were found to be statistically significant. Conclusion:Highest percentage of sealer coated perimeter was found to be of Tubliseal and lowest for FUJI-1.

Aim: The aim of this study was to evaluate the distribution of sealer at different levels of the root canal using three different sealers in a single-cone obturation technique. Materials and Methods: Thirty freshly extracted mandibular premolar teeth were selected and access opening was performed. Working length was determined. Cleaning and shaping were done till 25 size K file followed by ProTaper till F2 size. Teeth were then obturated with matching gutta-percha points with the following sealers: Group I, 10 teeth with zinc oxide eugenol sealer; Group II, 10 teeth with AH plus sealer; and Group III, 10 teeth with NanoSeal-S sealer. Teeth were cross sectioned at 3 and 6 mm from the apex. Color photographs of sections were taken at a magnification of ×40 using a camera connected to a stereo-operating microscope and the images were transferred to a computer. Sealer distribution was observed and the canal perimeters coated or uncoated with the sealer can be calculated using a computer digital imaging system. Results: Of the three groups, zinc oxide eugenol showed least sealer distribution. AH Plus and Nanoseal-S showed no significant difference between the distribution at the 3- and 6-mm levels. Conclusion: Both AH Plus and Nanoseal-S showed excellent sealer distribution when compared to zinc oxide eugenol.

“…7 Several types of endodontic sealers are commercially available, such as calcium hydroxide-based Acroseal and Sealapex, and epoxy resin-based AH Plus. 8 Sealapex and Acroseal are sealers containing calcium hydroxide, and their dissociation into calcium and hydroxyl ions alkalinize the environment, leaving it unfavorable to bacterial proliferation. 1 Moreover, calcium ions can react with carbon dioxide and reduce the breathing source of anaerobic bacteria.…”

Antimicrobial action of calcium hydroxide-based endodontic sealers after setting, against E. faecalis biofilm Abstract: Enterococcus faecalis are gram positive bacteria that can mostly resist endodontic therapy, inducing persistent infection in the root canal system. Endodontic sealers with antimicrobial activity may help eliminate residual microorganisms that survive endodontic treatment. The present study aimed at comparing the antimicrobial activity of Acroseal, Sealapex and AH Plus endodontic sealers in an in vitro biofilm model. Bovine dentin specimens (144) were prepared, and twelve blocks for each sealer and each experimental time point (2, 7 and 14 days) were placed and left in contact with plates containing inoculum of E. faecalis (ATCC 51299), to induce biofilm formation. After 14 days, the samples were transferred to another plate with test sealers and kept at 37°C and 5% CO 2 for 2, 7 and 14 days. The specimens without sealers were used as a control for each period. The samples were agitated in a sonicator after each experiment. The suspensions were agitated in a vortex mixer, serially diluted in saline, and triple plated onto m-Enterococcus agar. Colonyforming units were counted, and the data were statistically analyzed using ANOVA, Shapiro-Wilk and Kruskal-Wallis one-way tests (p < 0.05) to determine antimicrobial potential. Sealapex showed significant differences at all the experimental time points, in comparison with all the other groups. AH Plus and Acroseal showed antimicrobial activity only on the 14 th experimental day. Neither of the sealers tested were able to completely eliminate the biofilm. Sealapex showed the highest antimicrobial activity in all the experimental periods. The antimicrobial activity of all the sealers analyzed increased over time.
