When? Instruments should be sharpened lightly after each use; there are two Regular sharpening will enhance the
ways to evaluate whether the cutting edge is dull and requires sharpening: life of your cutter and will improve the RINSE AND CLEAN
1. Visual: The cutting edge should be inspected regularly in a good light (and if
quality of your work. Immediately after surgery, rinse instruments under warm
possible, under magnification)� If the cutting edge is blunt it will be rounded running water (NOT HOT)� Use only neutral pH detergents�
and reflect the light� A dull, non-reflective line indicates sharpness� UnILeteTdislRteunAnohgtoSsltrdOeeencrUoscm,aNmrbbeDoninddeeeCdfioLnfrsEotcrreuApmsscNeiansInstoNsdr.sGa,ll
2. Teflon Test Stick (DB-15): If the blade of the instrument runs smoothly over ULTRASONIC CLEANING
the testing stick, then it is blunt� A sharp instrument will grab into the stick
and removes small fragments of the plastic� It is recommended for regular instruments such as hand
instruments and forceps, following this procedure:
How? Generally, the instruments should be sharpened following this procedure: • Sort instruments carefully so as to include only instruments
1� Place one drop of sharpening oil (DB-OL) on the Arkansas stone�
compatible with ultrasonic cleaning�
Lubrication improves the movement of the instrument blade over the stone; • Place instruments in open position�
also, it prevents the metal particles from clogging the stone� • Make certain sharp edges are not touching other
2� Hold the instrument in one hand, while applying the stone to the lateral
surface angled with the face of the blade� instruments�
3� Position the stone to contact the heel of the blade and work toward the tip, • Do not combine different metals (stainless, copper, chrome
keeping the stone in contact with the blade throughout the sharpening
procedure� plated, etc�)�
4� Move the stone up and down with short strokes, placing more pressure on the • Change solution frequently to avoid accumulation of micro
down stroke� (Do not move the instrument, keep the instrument still)
5� Finish sharpening the instrument with a down stroke; this will prevent a organisms�
rough edge from forming� • After rinsing and before sterilization, inspect and dry the
6� Evaluate the sharpness with testing stick� If the blade is still dull, re-evaluate
the angle of the stone and repeat the sharpening procedure (steps 2-6)� instruments thoroughly�

SHARPENING OF SCALERS AND CURETTES Remember: Ultrasonic cleaning does not sterilize. Do not use
for TC instruments, sharp and delicate instruments
Sickle Scaler Toe End: the sickle scaler has a pointed tip and, therefore, the
stone is held straight as it nears the tip� STERILIZATION
Curette Toe End: the curette has a rounded toe, so the position of the stone is
adapted around the rounded cross-section� Autoclave (Steam Sterilization)
With both types of instrument, always finish on a down stroke to remove any
flash of metal� Time: 4 - 20 min� / Temperature: 130º - 134ºC (266º / 273ºF)
