Introduction: Root Canal Filling is the final procedure during root canal therapy, where endodontic sealers should have physical, chemical, and biological properties that help to reduce the population of residual bacteria and create a favorable environment for the repair of periapical tissues. The aim of this work was to compare the antibacterial capacity of AH Plus (Denstply®) and BioRoot RCS (Septodont®). Materials and Methods: Negative-Coagulase Streptococcus, Streptococcus salivarius, and Enterococcus faecalis were isolated from a necrotic pulp. They were tested by Minimum Inhibitory Concentration (MIC): 50 µl of saline solution and 100 µl of AH Plus and BioRoot RCS were used to perform the following dilutions of 1:2, 1:4, 1:8, 1:16, 1:32, 1:64, 1:128, 1:256, 1:512, 1:1024. Subsequently, the samples were cultured on Müeller- Hinton agar with sheep blood, to assess bacterial growth. Results: AH Plus showed growth up to 1:64 dilution and BIOROOT = 1:32 in E. faecalis while in Negative-Coagulase Streptococcus both cements showed growth at 1:2048 dilution, in S. salivarius there was no bacterial growth with both cements. Conclusion: AH plus (Denstply®) and BioRoot RCS RCS (Septodont®) are cements that provided an effective bacterial activity in isolated microorganisms: E. faecalis, S. Coagulase Negative and S. salivarius.

Case Selection

The evaluation of root canal therapy done in several places by different authors sh0'0' high rates of failures. This is due to unskilled operators which disregard the complex endodontic morpholow as well as to difficulties with endo/radiographic techniques. Failures occur due to improper case selection, by missed canals or by technical problems such as: poor assepsis, poor lateral condensation during root canal filling, short fills and over extended fills. Separeted instruments or Silver points enhance the chances of failures. The author encourages retreatments instead of radiographic follow ups longer than 5 years: is it a carefull observation or a supervised neglection?

<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>

Abstract Background: This study aims to compare the percentage of dentin removed, instrumentation efficacy, root canal filling and load at fracture between contracted endodontic cavities and traditional endodontic cavities in premolars. Methods: Forty extracted intact human first premolars were imaged with micro-CT and randomly assigned to CEC or TEC groups. Minimal CECs were prepared with the aid of 3D-printed guide template, canals were prepared with a 0.04 taper M-Two rotary instrument and cavities were restored with resin. The specimens were loaded to fracture in an Instron Universal Testing Machine after a fatigue phase. The data were analyzed by the independent samples T test and Mann-Whitney U test, appropriate post hoc tests. Results: In the premolars tested in vitro, CECs conserved coronal dentin in premolars with two dental roots but no impact on the instrument efficacy, the root canal filling or the biomechanical responses compared with TECs. Conclusion: The results of this study did not suggest that CEC could improve the fracture resistance of the endodontically treated premolars. The instrumentation efficacy and the percentage of filling material did not significantly differ between CECs and TECs in the premolars.

The classifications of bioceramic materials based on their chemistry and specific use in endodontics are presented. The physicochemical and biological properties of various types of materials, as well as the features of their clinical application, are described.

This review aims at describing and comparing materials commonly used in root canal therapy, the cytotoxicity,histopathological, microbiological and clinical aspects of a iodoform-based paste (Guedes-Pinto Paste-GPP) used in endodontic treatment of primary teeth. GPP has shown excellent biocompatibility to pulp fibroblasts and mild inflammatory reactions, having been well-tolerated by the periapical and connective tissues. Moreover, GPP bactericidal and bacteriostatic effects against many oral microorganisms were also demonstrated. Regarding clinical trials, the GPP technique has achieved success rates when considering clinical and radiographic examinations. In the face of all the above mentioned results, this paper would like to propose the use of this endodontic material as a root canal filling for primary teeth.
