step-back technique uses a combination of hand instruments (files) and rotary instruments (Gates- Glidden drills and Peeso reamers) to achieve adequate coronal flare before apical root canal preparation.
What is Schilder’s technique in endodontic treatment?
Vertical Compaction (Schilder’s Technique) A total of 290 patients were treated using the standardized step-back technique for canal preparation, which were filled with either lateral condensation or vertical compaction in one single session.
What is ProTaper used for?
Importantly, precurved manual ProTaper files are the instruments of choice for managing canals that exhibit difficult anatomy, as an example a sharp apical curve, an iatrogenic mishap, such as a ledge, or a pathological defect resulting from internal resorption.
What is the concept of ProTaper system?
The ProTaper system is the alternative to all other file systems in which each file has a fixed taper. Each ProTaper file has a variable changing taper over the length of its cutting blades.
What is the difference between K-files and H files?
All K-files are mainly intended for rotary motions inside the canals. On the other hand, H-files are specially designed for shaping canals after they are previously cleaned and enlarged with K-files. They are made out of the ground wire and have a tear-drop cross-sectional shape.
How do I choose a master apical?
Primarily and ideally, the MAF should be based on the pre-existing diameter of the MC. Large canals and large pre-existing MC diameters facilitate creation of larger MAFs. The converse is true. The diameter of the MC is determined through a process called ‘gauging’.
What is the difference between ProTaper gold and ProTaper universal?
It also has a noncutting tip design, allowing the instrument to follow the original shape of the root canal. The ProTaper Universal has the same features. One important difference between these systems is that the ProTaper Gold has been metallurgically enhanced through heat-treatment technology.
What is a ProTaper?
ProTaper files have a changing helical angle and pitch over their cutting blades, which reduces the potential of an instrument from inadvertently screwing into the canal. 6. The ProTaper files each have a noncutting, modified guiding tip.
What is the difference between ProTaper next and gold?
The file is exactly the same as ProTaper Universal, but with the new GOLD NiTi it is much more flexible and the file isn’t straightening out in the canal, giving therefore less resistance, which is a good thing.
