Endodontic Sealers

Recently, endodontic sealers based on injectable bioactive materials were proposed to improve the filling of anatomical irregularities during root canal obturation. In this context, this preliminary work investigated the possibility of realizing a new calcium phosphate-based composite sealer for root canal filling with an optimized composition on setting kinetics and dentin tubules occlusion. Several calcium phosphate/liquid phase mixtures were initially evaluated for their workability, finding two suitable formulations. Both of them contained 66 wt.% of a nano-apatite-based cement (solid powdered phase). The liquid phase (34 wt.%) comprised 13.6% propanediol and 20.4% PEG 1000 (formulation 1), and formulation 2 comprised 27.2% glycerin and 6.8% PEG 200 (formulation 2). Then, these formulations were tested by means of permeability measurements and observation by scanning electron microscopy of treated model dentin samples. Both formulations succeeded in occluding dentinal tubules: the first one was able to create a full-bodied layer on dentin surface and, moreover, to resist, at least to a large extent, against citric acid attack. The second one showed a lower effectiveness after citric acid exposure. The composite compound that better satisfied the overall required characteristics of use, workability and sealing capacity was formulation 1.

Abstract Background Three-dimensional obturation of the root canal system is mandatory for a successful root canal treatment. Using a filling material with optimal properties may enable the root canal to be sealed well and therefore obtain the desired obturation. Objective To develop a new injectable paste endodontic filling material using calcium phosphate powder and a styrene–butadiene emulsion polymer. Methods The powder phase comprised an equivalent molar ratio of tetracalcium phosphate, anhydrous dicalcium phosphate, bismuth oxide, and calcium chloride. The liquid phase comprised a styrene–butadiene rubber emulsion in distilled water. The powder and the liquid were mixed to achieve a paste consistency. The paste was subjected to various tests including flow, setting time, dimensional change, solubility, and radiopacity to indicate its suitability as a root canal filling material. All these tests were conducted according to the American National Standards Institute–American Dental Association for endodontic sealing materials. After passing these tests, the paste was submitted to an injectability test. Results The material showed acceptable flowability with 19.1 ± 1.3 min setting time and 0.61 ± 0.16% shrinkage after 30 days of storage. We found the highest solubility at 24 h (6.62 ± 0.58%), then the solubility decreased to 1.09 ± 0.08% within 3 days. The material was more radiopaque than a 3 mm step on an aluminum wedge. Furthermore, the material showed good injectability of 93.67 ± 1.80%. Conclusions The calcium phosphate powder in styrene–butadiene emulsion met basic requirements for a root canal filling material with promising properties.

Antimicrobial Effectiveness

Aim: this study was conducted to evaluate the antimicrobial effectiveness of 6 root canal filling materials and a negative control agent against 18 strains of bacteria isolated from infected root canals of primary molar teeth using agar diffusion assay. Materials: Aloevera with sterile water, Zinc oxide and Eugenol, Zinc oxide-Eugenol with aloevera, Calcium hydroxide and sterile water, Calcium hydroxide with sterile water and aloevera, Calcium hydroxide and Iodoform (Metapex) and Vaseline (Control). MIC and MBC of aloevera was calculated. Results: All materials except Vaseline showed varied antimicrobial activity against the test bacterias. The zones of inhibition were ranked into 4 inhibition categories based on the proportional distribution of the data. All the 18 bacterial isolates were classified under 2 groups based on Gram positive and Gram negative aerobes. Statistical analysis was carried out to compare the antimicrobial effectiveness between materials tested with each of the bacterial groupings. Conclusion: Aloevera + Sterile Water was found to have superior antimicrobial activity against most of the microorganisms followed by ZOE + Aloevera, calcium hydroxide + Aloevera, ZOE, calcium hydroxide, Metapex in the descending order and Vaseline showed no inhibition.

Agar Diffusion Test

<p>Endodontic treatment in deciduous teeth is very important so that we can preserve the primary dentition and thus promote appropriate craniofacial development. However, the use of filling pastes that have some important biological properties for the preservation of the tooth is required. The objective this study was to evaluate the in vitro antimicrobial activity of two root canal filling pastes in deciduous teeth, Vitapex® and Calcipex®, on microbial species commonly found in endodontic infections (Candida albicans, Enterococcus faecalis, Streptococcus mutans, Streptococcus sanguinis, Escherichia coli and Staphylococcus aureus), using the agar diffusion test. The experiment was carried out on BHI (Brain Heart Infusion) plates in four equidistant points, which were immediately filled with the sealers Vitapex® and Calcipex®. The<br />chlorhexidine gluconate 1% (CHX) and distilled water were used as positive and negative controls, respectively. After incubation of plates at 37 °C for 24 h, the diameter of the growth inhibition zones around the wells was measured (in millimeters) with a digital caliper with reflected light. The test was performed in triplicate and data were submitted to ANOVA and Tukey’s test (α = 0.05). Both pastes had antimicrobial activity, but Calcipex® was more efficient for most strains. The halo formed in the experiments with S. mutans and S. sanguinis was similar for both pastes. This study suggests that Calcipex® had the highest antimicrobial property with respect to the microorganisms studied.</p>
