What is the difference between K type files and Hedstrom files?
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. The location of the aberrations depended largely on the original shape of the canal and in particular on the position of the beginning of the canal curve.
What are Hedstrom files made of?
stainless steel
Hedstrom files made of stainless steel, made by VDW, gave the best cutting efficiency for sizes 25 and 35. Overall, under the conditions of this study. Hedstrom files had better cutting efficiency than S or U files.
What is a root canal file?
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.
Which is better K file or 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 are K files?
K files are the universal standard for canal negotiation, shaping, and recapitulation of root canal systems. They are generally used with a quarter turn “watch-winding” motion and vertical pull.
What is the difference between reamer and K file?
K File Series are of two types: K File and K Reamer. K Reamers have a triangular cross-section with loose spirals around the flute. Reamers have 2.5 times more cutting efficiency. They have a reaming motion.
What if a file breaks during root canal?
A broken piece of a file can be challenging to remove for many general dentists. If the tip of the file is left, a dentist would need to navigate around it and seal the apex or tip of the tooth root. If the broken piece is blocking the apex, it decreases the chances of successful root canal treatment.
Are K files end cutting?
Standard K files have an “active” (cutting) tip. Specifically, the tip of a standard K file is quite sharp due to the acute transition from the tip to the fluting. An active tip results in an increased possibility of ledging and canal transportation.
What is the difference between K file and K reamer?
How do I use K files?
Premier K-Files are used to enlarge canal after debridement with a reamer. After reamer, use a file one size smaller than the reamer so that the fragments of dentinal shavings can be carried away from the root-canal walls. Use in clockwise direction (1/4 turn only), then withdraw.
Do K files expire?
7) A frequent verification is recommended with small size ReadySteel® K-File in order to prevent any blockage. Irrigate abundantly while shaping the canal. The shelf-life is 5 years. Expiry date is indicated on the packaging.
What are Gates Glidden drills used for?
Among the instruments used for canal preparation, Gates-Glidden (GG) drill is extensively used for the preparation of direct areas of root canal owing to high cutting capability, easy application, and low price [6].
How do I identify h file and K file?
Hand files are classified into three categories: K-files, K-reamers, and H-files. The main differences among these files are in the design of cross-sectional shape and number of threads. K-files have a square cross-sectional shape, while K-reamers has a triangular shape.
