Objective:The aim of this study was to assess the impact of glide path preparation, performed with PathGlider 0.15 (Komet Brasseler GmbH & Co., Lemgo, Germany) and PathGlider 0.20 (Komet Brasseler GmbH & Co., Lemgo, Germany), on the centering ability of 25-size F6 Skytaper in J-shape simulated root canals, compared with no glide path executed.Materials and Methods:Sixty J-shaped ISO 15 0.02 taper endo training blocks (Dentsply Maillefer) were assigned to three groups (n = 20 for each group). Photographic images were taken on endoblocks before and after shaping procedures. After superimposition, the software AutoCAD 2013 (Autodesk Inc., San Rafael, USA) was used for record the centering and shaping ability at 9 different levels from the apex.Results:Shaping procedures including the using of PathGlider 0.20 resulted in a lower amount of resin removed and in a clear improvement of centering ability of the Skytaper 0.25 at almost all reference point levels.Conclusions:Within the limitations of this study, it could be concluded that the glide path procedure, performed with the PathGlider 0.20 before the shaping with 25-size F6 Skytaper, might determine a lower amount of resin removed and a better centering ability compared with the groups without glide path procedure and those treated with PathGlider 0.15.

“…10 K-file to establish the 16-mm working length (Maillefer-Dentsply, Ballaigues, Switzerland), pathfiles no. 1, 2, and 3 (Maillefer-Dentsply, Ballaigues, Switzerland) [26] to produce the glide path [26], and ProTaper Universal instruments S1-S2-F1-F2-F3 (Maillefer-Dentsply, Ballaigues, Switzerland) for the final phase of shaping [3]. The final shaped endo training blocks were divided into two groups, composed of 25 samples each, assigned to either MDA [27] or PUI [28].…”

“…Endodontic treatment involves a procedure composed of the following sequence of steps: tooth anesthesia, operative field isolation, opening of the pulp chamber, canal scouting, shaping and cleansing of the canals, and three-dimensional (3D) obturation [1]. These phases lead to root canal disinfection, shaping [2,3], and filling [4]. All the steps are important for achieving endodontic success, but cleansing has an essential role in reducing the bacterial load inside the root canal system [5].…”

Effectiveness of Vapor Lock Effect Removal in Endo Training Blocks: Manual Dynamic Agitation versus Passive Ultrasonic Irrigation

Root canal cleaning plays an important role in endodontics. In most cases, root canal cleaning is performed using irrigants, such as sodium hypochlorite or EDTA (ethylenediaminetetraacetic acid). The efficacy of these irrigants may be compromised by different phenomena, such as vapor lock. Different methods can be used to overcome this problem; in this paper, we compare the efficacy of two such methods: manual dynamic agitation (MDA) and passive ultrasonic irrigation (PUI). We shaped 50 endo training blocks, which were divided into two groups of 25 samples each, into MDA or PUI groups. In both groups, the vapor lock was produced by delivering a watery solution using a disposable syringe with a tip-opened needle. Using the MDA technique, vapor lock was removed in 15/25 cases. The PUI technique produced the same results in 17/25 cases, where vapor lock was only reduced, not removed. The MDA method produced an average reduction in vapor lock of 80%, whereas the PUI method yielded a 55% reduction. The differences among groups were assessed through a Mann-Whitney U test, and the results had a p-value of 0.0013, which was considered to be statistically significant. The MDA method was able to effectively remove vapor lock. PUI, however, was only able to reduce but not remove vapor lock.

“…For the non-autoclavable and disposable material as for gutta-percha or resin cones [96], the most suitable method to reduce the bacterial contamination present on these cones is disinfection by hypochlorite immersion with concentrations ranging from 2% to 5.25% for a minimum time of 5-10 min. Similarly, chlorhexidine can be used in a concentration equal to 2% for a shorter period (data in the literature suggest 1-2 min), or 2% peracetic acid can be used for 5 min [59].…”

Endodontic treatment consists of different working procedures, such as the isolation of the operating field, pulp chamber access, and cleaning and shaping phases with at last the need of a three-dimensional filling of the canals. Each step requires a series of single-use or sterilizable instruments. We have performed a systematic review of different sterilization and disinfection procedures aiming at drawing up a disinfection and sterilization procedure to be used on endodontic instruments. A search on PubMed and Scopus was carried out using the following keywords: “endodontic sterilization,” “endodontic autoclave,” “decontamination dental bur,” “sterilization dental burs,” and “gutta-percha points sterilization.” Eligible articles were included in the qualitative and quantitative analysis. Results of the meta-analysis showed that the most effective method in sterilization is autoclaving. The qualitative analysis showed that the use of single-use or first-use instruments requires presterilization or sterilization procedures, and for reusable tools, attention must be paid to the removal of debris deposited on the blades, not easy to remove manually.
