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.

Antimicrobial Effectiveness

<p><strong>Objective:</strong> The aim of this study was to evaluate the antimicrobial effectiveness of calcium hydroxide associated with a two conventional (anesthetic liquid and olive oil) and a new vehicle (Triethanolamine). <strong>Material and methods:</strong> Initially, microorganisms were collected from four upper incisors presenting unsatisfactory root canal treatments and persistent apical periodontitis from the same patient using sterile absorbent paper cones placed inside the root canal following initial access and root filling removal. Next, they were grown in a BHI culture medium for 24 h. Afterwards, they were placed in 10 Petri dishes with 3 holes, where different formulations of the medications studied were placed. After 48 and 72 h, readings were taken of the growth inhibition halos. <strong>Results:</strong> After using Kruskal-Wallis test with significance level of 1% (α = 0.01) it was observed that, calcium hydroxide associated with Triethanolamine, produced results similar to those produced by the anesthetic liquid. Both combinations were superior to the association with olive oil. <strong>Conclusion:</strong> Considering the results of this <em>in vitro</em> study, it is possible to consider that Triethanolamine can be a viable alternative to be used as a vehicle associated with the calcium hydroxide.</p><p><strong>Keywords:</strong> Vehicles; Calcium hydroxide; Endodontics.</p>

Root Canal Sealers

Aim and Design: Sealers with prolonged antimicrobial activity are needed by the fact that microorganisms are commonly recovered from teeth with failed endodontic therapy. The aim of this study was to evaluate the duration of antimicrobial activity of ten root canal sealers (Apexit plus, Tubli Seal Xpress, Endoflas FS,Endomethasone, Endomethasone N, AH Plus, Epiphany, EndoRez, Ketac Endo, Roeko Seal) against Enterococcus faecalis and Candida albicans by the agar diffusion test. The zones of inhibition were examined immediately and after 24, 48, 72 hours, 5 and 7 days. Statistical analysis was done using Kruskal - Wallis test and Mann Whitney U test. Results and conclusions: Against Enterococcus faecalis, Endoflas FS showed the largest inhibitory zones immediately and 24 hours after manipulation, whereas, there was no significant difference between Endoflas FS and Endomethasone after 48 hours. Against Candida albicans, Endoflas FS performed better than the other sealers. All the sealers (except AH Plus, Epiphany and Roeko Seal) demonstrated higher antimicrobial action in the first 24 hours after manipulation The antimicrobial action of all the sealers (except AH Plus and Roeko Seal which showed no antimicrobial activity in any studied time and Epiphany which ceased to show any antimicrobial action after 24 hours) decreased significantly with time.
