Application of XP-endo® Shaper and Finisher-R for retreatment cases

Abstract

Root canal retreatment is in most cases challenging. The practitioner may be confronted to obstacles and/or complications such as posts, perforation, ledges etc. and the removal of the gutta-percha may prove to be difficult. The main goal of the retreatment is to remove any material and debris blocking the canal walls from being disinfected. Conventional rotary instrumentation creates round spaces within the root canal system and the filling pressing the non-removed gutta-percha into the irregularities of the root canal system. This will make proper removal of the whole root canal material more difficult and time-consuming. Recently, the instruments XP-endo® Shaper and Finisher-R have been introduced into the market. The material features of these instrument allow them to expand and adapt to the root canal anatomy during instrumentation. The XP endo Shaper is used to more efficiently remove gutta-percha and the subsequent application of the XP endo Finisher-R will additionally improve root canal surface disinfection. The lecture will take on the clinical protocol in the use of the XP endo instruments and present relevant research results of the current topic.

Effect of Asymmetric Geometry and Heat-Treatment on the Behavior of Rotary Root Canal Instruments

Abstract

Current concepts in root canal system preparation still largely rely on mechanical instrumentation. Two major factors affect the choice of instruments for root canal preparation: its ability to achieve the root canal shaping and its safety. The file accuracy is linked to its resistance to fracture, its lack of threading in dentinal walls when used in continuous rotary motion and its ability to respect the initial canal path in curved canals. The original canal anatomy must be maintained. Most of these factors depend on the profile of the instrument and so, on the design of its active part. When used in a continuous rotating motion, even at low speed, Ni-Ti shaping instruments may absorb lots of constraints: torsional stresses, cyclic fatigue, and cutting fatigue. Decreasing those constraints increase the security of shaping. For this purpose, managing the initial constraints at the junction of crown and root with an opener to create sufficient space or glide path for file’s tip is strongly recommended. In the last decade the geometry of the instruments evolved tremendously. In 2008, the emergence of an asymmetrical cross section with the Revo-S® has reduced the constraints and improved the cleaning ability of endodontic instruments. In their quest to increase flexibility of NiTi alloy without compromising its super elastic properties, Micro-Mega introduced an innovative cross section and a post machining thermo mechanical treatment called T wire. These improvements were used to produce a new opener One Flare® and a new file sequence. This short sequence, 2Shape®, will allow clinicians to shape almost all canal anatomies with only two files. The new asymmetric section will be described and its mechanical behavior will be extensively explained.

Objectives

At the end of the presentation, the participants will be able to describe the different advantages of asymmetric files and will be able to use OneFlare® and 2Shape®, safely and easily in the widest range of canal anatomy.

New Innovations in Glide Path Management and Shaping Canals with Gold Technology

Abstract

The endodontic Glide Path is the natural space occupied by the once healthy dental pulp. It does not need to be fabricated. It needs to be explored, followed, enlarged and reproduced from canal orifice to apical terminus. A reproducible Glide Path will facilitate the use of all mechanical nickel titanium instruments to shape the canal fully to length and minimise the risk of instrument breakage, preventing ledges, blockages and perforations. The Glide Path can be enlarged with dedicated mechanical glide path files that expand the original anatomy, improve shaping results, reduce chair time and help to remove debris coronally out of the canal. With so much emphasis placed on final instrumentation, it is important to remember that final shape is irrelevant without a Glide Path that follows the natural canal anatomy to its terminus. The Glide Path is the secret to both rotary and reciprocating shaping procedures. The exciting development of WaveOne® Gold in 2015 has introduced many colleagues into a new world of mechanical shaping techniques. An asymmetrical reciprocating movement and unique design is valued for its simplicity where only one file is needed in 80% of cases. Optimised tip diameters, tapers and an altered cross section produces a file that really improves safety, efficiency and flexibility when shaping canals. Altering the metallurgical properties of NiTi files by heat treatment to improve flexibility and more importantly the fatigue life of the instrument has led to a significant reduction in the incidence and fear of breakage. With little “shape memory", WaveOne® Gold has the ability to treat some of the more complex challenges seen in everyday endodontic practice such as those with long, curved and narrow canals. These cases are now within the comfort zone of many colleagues. The WaveOne® Gold system takes simplicity and treatment success to another level.

Objectives

As a co-developer of the entire WaveOne® Gold system Julian Webber will review those design features that have enhanced performance and offer clinical hints and solutions to achieve exceptional endodontic outcomes.

Apex in vacuo. Use of partial vacuum force in endodontics

Abstract

In the partial vacuum of scientific consensus and clinical guidelines as to optimal irrigation, we could use the partial vacuum of negative pressure irrigation systems to achieve multiple beneficial goals to enhance root canal cleaning: - increase overall volume of irrigant(s);

- enhance replacement of solution in the canal space;

- deliver irrigant(s) into the apical third with no vapour lock;

- clean the apical third safely with zero irrigant extrusion beyond apex.

Combining the partial vacuum created by the appropriate equipment with the proper, evidence-based irrigation sequence can make root canal therapy more efficient, predictable, successful, safe as well as speedy.

Methods of activating endodontic irrigation

Abstract

In endodontic disinfection protocols the activation of endodontic irrigation solutions is widely recommended. In this lecture the scientific evidence for activation of irrigants with ultrasonics, sonics and Er:YAG laser is evaluated. Clinical aspects and pitfalls using these methods will be discussed. It will be demonstrated that wrong handling with either method of activation may lead to unwanted effects on dental hard tissues or surrounding soft tissues. Special emphasis is given to a new sonic activation device operating at 6'000 Hz.

Evaluation of the influence of heat-treatment on single files used in continuous rotation and reciprocation motion

Abstract

Many in-vitro endodontics studies use resin blocs, to standardize their samples. However over the last few years several companies developed 3D models. These models are the exact replicas of real teeth, thanks to 3D printing. Three models, MM-Tooth® (Micro-Mega), True Tooth® (VDW) and Dentalike® (Dentsply), are compared to resin blocs by microCT analysis. This study showed that following the model used to achieve an root canal preparation the results are very different and that resin blocs should not be the gold standard for a microCT study. Single NiTi shaping files with and without heat-treatment, used in continuous rotation (One Shape®, Micro-Mega) or in reciprocating motion (Reciproc 25®, VDW) are then compared using the proper model for a 3D microCT analysis. These two files were selected as the only change they underwent was NiTi heat-treatment.

Aims

The lecture will address the following interrogations: Does the heat-treatment of the NiTi alloy has the same impact following the motion used? Does it allow better centering? A faster preparation? A safer preparation?

Nickel-Titanium instrumentation: clinical applications of endodontic files properties in the heat-treatments’ era.

Abstract

Mechanical instrumentation represents a crucial step in the control of intracanal microbial infection for successful root canal treatment. However, the complexity and variability of root canal anatomy required different instruments and techniques to use NiTi files in order to respect the original anatomy as much as possible. For these reasons, heat-treated NiTi instruments were introduced in the market allowing always more efficient, safer and easier root canal treatments. Traditional or thermally treated NiTi files have different mechanical properties that should guide the clinician in their choice and way to use them depending on clinical conditions and/or different phases of endodontic treatment, from early coronal enlargement to apical finishing. Moreover, the root canal anatomy is often oval and therefore different instruments and techniques should be introduced in order to work efficiently also in no-circular channels. Flexibility, fracture resistance and lack of super elasticity of heat-treated controlled memory Hyflex CM and EDM files will be discussed in comparison with other traditional or differently heat-treated files suggesting a specific clinical use of these instruments to obtain adequate and safe anatomically driven preparations even for highly curved canals.

Objectives

To evaluate the advantages and disadvantages of conventional and heat-treated NiTi files in relation with the different phases of root canal treatment and/or clinical situations;

To understand mechanical properties of rotary controlled memory and electrical discharge machining files;

To suggest clinical uses and applications of heat-treated HyFlex EDM & CM rotary files properties.
