Kinds of root canal files. They include K-files, Hedstrom files (H-files), reamers and barbed broaches. Each type has its own characteristic design (often a function of its method of manufacture), and that dictates how it’s most efficiently used.
What are files used for in endodontics?
Endodontic files and reamers are surgical instruments used by dentists when performing root canal treatment. These tools are used to clean and shape the root canal, with the concept being to perform complete chemomechanical debridement of the root canal to the length of the apical foramen.
What is C file in endodontics?
Maillefer C-Files are made of specially treated stainless steel for amazing stiffness and strength. The result is easier access to challenging, calcified canals. Heat-tempered steel for stiff performance. Twisted file design for greater strength.
What is the master file in endodontics?
The MAF is the last file taken to the minor constriction (MC) of the apical foramen. Its diameter becomes the final prepared diameter of the canal at the MC.
What is the difference between K file and h file?
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.
What file is used in a root canal?
Endodontic files and reamers are surgical instruments used by dentists performing root canal treatment. They are used to clean and shape the root canal removing dead, damaged or infected material to the opening at the apex of the tooth root. Using the files provides a shape that is receptive to subs equent filling.
What is the difference between Hedstrom and K files?
Both file types prepared straight canals in an appropriate manner but the majority of prepared curved canals were hourglass in shape. In general, K-files created zips which were wider and thus more pronounced than those produced by Hedstrom files. Wide ‘danger zones’ were also regularly created.
What does a .h file do?
H files allow commonly used functions to be written only once and referenced by other source files when needed. H header files are typically used to store C function declarations, as well as macro definitions, which can be used by multiple source files.
What is tug back in endodontics?
Tug-back is defined as a slight frictional resistance of a master point to withdrawal, which indicates a relative degree of adaptation at least in 2 dimensions, according to the American Association of Endodontists [6].
How do I stop apical?
This apical stop is prepared through the use of successively larger files to the working length. While apical stop preparation can be done using conventional stainless-steel files, rotary NiTi files produced especially for the instrumentation of the apical part of the root canal can also be used for this purpose.
What is the classification of endodontic instruments?
Classification. Endodontic instruments can be divided into 4 different groups: GROUP 1. Instrumentation used for manual root canal procedure. GROUP 2. Instrumentation for mechanized or rotary duct procedure. GROUP 3. Trephines for mechanized use (Weight burs, Gates glidden, etc.).
Do all endodontists use the same file?
Depending on the clinical case, one file or another will need to be used, however, this also depends a lot on the endodontist’s methodology, as some are more conservative than others. In fact, many endodontists alternate and combine files.
What is Hedstrom file used for in dentistry?
They are also used for removal of root canal filling materials e.g. gutta percha during secondary root canal treatment. An example of Hedstrom files available on the market are Edge Hedstroms (EdgeEndo, Albuquerque, NM). This file is used to remove pulp tissue (extirpation) during root canal treatment.
What are the different types of K files available?
This information can help determine strategies or avoid complications before moving on to rotary instruments. The different K files available on the market include K-Flex (Sybron-Endo, Orange, Ca, USA), K-Flexofile (Dentsply-Maillefer, Ballaigues, Switzerland), and EdgeK-File and EdgeK-File NiTi nickel titanium (EdgeEndo, Albuquerque, NM).
