3D NiTi technology with expandable feature and its application on Endodontics instrumentation.


Recently a new NiTi wire (MaxWire™) and instrument system (XP-endo®) have been introduced. Using the principles of shape memory of NiTi alloy the MaxWire was developed to be malleable at room temperature (Martensite phase) and transform to a specific shape at body temperature inside the root canal (Austenite phase). XP-endo instruments are designed for 3 uses: 1-XP-endo Shaper - one file for the 3D shaping of the canal;

2-XP-endo Finisher – used after the Shaper (or traditional round files) in order to reach tissues or debris not reached in the shaping phase and

3-XP-endo Retreatment - to efficiently remove obturation materials from the root canal walls left behind after shaping instruments have been used.

Preliminary studies on XP-endo files have shown remarkable efficiency for maintaining the original shape of the canal while producing less dentinal debris blocking the irregular areas or isthmus areas. In addition, even though minimal number of instruments is used, almost no stress is produced on the canal walls. This presentation will explore the technical, biological and clinical aspects of this new 3D instrument system.


At conclusion, participants should be able to:

1. Understand the technological challenges of traditional endodontic instruments to predictably clean the root canal.

2. Present the physical and clinical characteristics of the new XP-endo files

3. Demonstrate the clinical use of XP-endo files

4. Present the latest on-going and published studies on these instruments.

Reciprocation – the easy practical way


Modern instrumentation of the root canal, reciprocation or rotary – introduction of a new system – S1 reciprocation makes it easy. Rotary instrumentation of the root canal with rotary instruments has dominated the market for 20 years. The drawbacks have been many instruments and instrument fractures. The last years, reciprocating instrumentation has been introduced. It has promised fewer instruments, used once and simpler instrumentation sequence and technique. Sendoline is a Swedish company manufacturing endodontic instruments since 1940 and one of their most important product innovations is the Hedström-file (H-file). The company is experienced in producing rotary instruments for preparation of the root canal and has recently introduced a new single-file reciprocating system, S1, that will make the instrumentation of the root canal easier and more straight-forward. Instead of advanced special electric motors with foot-pedals controlling the reciprocation movement, Sendoline has developed a mechanic handpiece with integrated gearbox which creates the reciprocating motion 180° clockwise and 30° anti-clockwise which will make the handling easier. The lecture will address the benefits and drawbacks of rotary and reciprocation instrumentation and how Sendoline has addressed the issues and how the company developed the new S1 reciprocation system.

The MANI-Silk System - rotation and reciprocation for a safe and effective canal preparation in daily practice.


In daily practice the root canal preparation is carried out mainly with mechanical instruments used in a rotary or reciprocating motion. Major risks such as instrument separation or the alteration of the root canal anatomy can occur and increase the likelihood of treatment failure. By choosing an instrument used in a specific motion type practicians try to minimize the risks mentioned above. Wouldn't it be convenient to choose an instrument that can be used either in rotation or reciprocation to combine the advantages of these motion types during root canal preparation? What are the advantages and disadvantages of rotary or reciprocating motion? What impact has the instrument geometry on the fracture risk or the instrument flexibility? Can a special thermic treatment increase the flexibility and reduce the fracture risk of the instrument?


This presentation will discuss the advantages and disadvantages of rotary and reciprocating NiTi instruments and highlight the concept using the MANI-Silk instruments in both motion types in order to achieve a good preparation result in an efficient and safe manner in daily practice.

Reciproc Blue: the next generation of reciprocation


The concept of canal preparation with only one mechanical instrument used in reciprocation was introduced several years ago. Studies and clinical research have shown the efficiency and the safety of the Reciproc® instrument in the preparation of the majority of canals without creating a glide path, and in the retreatment procedure. Reciproc® blue, a thermally treated instrument is an improved version of the original Reciproc® instrument; it has an increased resistance to cyclic fatigue and a greater flexibility enabling a safer and smoother canal preparation procedure, and a wider range of clinical applications. Reciproc® blue will be introduced in this presentation. The physical properties of this instrument will be discussed with emphasis on their impact on the clinical applications. Preparation of the majority of the canals including 2nd mesio-buccal canals in maxillary molars, and narrow and curved canals with only one Reciproc® blue instrument without an initial canal negotiation and without a glide path will be described. The need to create a glide path in some canals with a reciprocating glide path instrument, R-Pilot®, will also be discussed.

Shaping root canals Safely and Swiftly with a Simple sequence.


Major changes in the field of instrumentation and shaping techniques have set a new course for endodontics in the last decade. Newer instruments are generating predefined canal shapes with respect to canal anatomy and minimal invasive principles. In the first part of the presentation, an overview of Modern advancements in shaping instruments designs as well as thermomecanical treatments and its implementations on mechanical properties of the files will be explained. The concepts behind modern endodontics will be revisited and discussed from a clinical point of view. Does coronal flaring comply with the minimal invasive requirements? Do we still apply the shaping techniques principles? In the second part the new Orifice opener, One flare®, and shaping sequence, 2 Shape ® from Micro-Mega will be described. The innovative file designs with different geometrical characteristics for each instrument will be revealed. The implementation of these designs and their capabilities to meet the requirements for each clinical scenario will be explained and endorsed with an extensive literature review , experimental studies and clinical cases.


At the end of this presentation, attendees will be familiar with the new files and their advantages. This will enhance their capabilities to safely and swiftly shape the widest range of canal anatomies; from curved and restricted to straight and large canals with a simple sequence of two rotary file per challenge.

PIPS – hovering laser activated irrigation. The future or already the present?


The most important objective of endodontic treatment is the eradication of microorganisms from the root canal system. Numerous species of bacteria in the root canal system and the organisation of biofilm with its strong adhesion to the root canal wall and into dentinal tubules make thorough cleaning of the root canal system very challenging.

Besides the mechanical preparation of the main root canal, irrigation with solutions such as NaOCL and EDTA is crucial in terms of the reduction of microorganisms. The activation of irrigants by sonic or ultrasonic devices leads to a further reduction of bacterial counts, but these techniques have drawbacks: sonic activation is not able to produce cavitation effects and thus is not able to remove biofilm or debris sufficiently. The use of ultrasound leads to better results, but recent studies suggest that the effects have been overestimated. Furthermore, the use of ultrasonic files in curved canals can cause grooves or even ledges in the root canal.

Recently, the activation of endodontic irrigants by laser devices has come into the focus of science. The PIPS technique was introduced in 2010 by DiVito et al. A specially designed laser tip is placed just over the entrance to the root canal. Using an Er:YAG laser and special parameters, the activation of the irrigants leads to profound cleaning effects in the whole root canal system. A number of studies show that the cleaning effect, especially in terms of biofilm, smear layer and debris removal, is by far superior to every other known technique, even in areas as difficult to reach as ramifications, lateral canals and dentinal tubules.


This lecture aims both to present the scientific background of PIPS and to focus on practical working experience of an endodontist who uses PIPS every-day.

Operative dentistry and Endodontology with biocompatible and bioactive materials - just a hype or more?


Cements based on calcium silicate include materials such as ProRoot MTA, MTA Angelus and Biodentine are distinguished by biocompatibility as well as bioactivity and have sealing characteristics. Biodentine, in addition, has dentin-like mechanical properties. Because of the better material properties of calcium silicate cements, these materials are an interesting alternative to conventional, calcium hydroxide-based materials or other cements. Biodentine can be used on dentin defects in the area of the crown and root, and have a positive effect on vital cells of the pulp and the periodont because of the biocompatibility and bioactivity. The aim of a root canal obturation is a sealing of the entire root canal system without any voids in order to minimize the risk of bacterial reinfection. Further requirements for the root canal sealers are - beside biocompatibility - antibacterial properties, ability to adhere to the dentin walls, radiopacity, dimensional stability and insolubility in tissue fluid. Especially because of biocompatible and bioactive properties of calcium silicate sealers, these materials are an interesting alternative to conventional, e.g. epoxy resin-based sealers. Hence, sealers based on calcium silicate are an innovative material for root canal obturation which may offer new perspectives in the treatment strategy. For this reason, a number of companies have also recently offered root canal sealer on a calcium silicate basis like BioRoot RCS. This lecture is intended to provide an overview of the calcium silicate cements and sealers available on the market as well as the possibilities and limitations of these new materials.
