7. Changing Scaler Tips.
a. Hold the scaler tip by the metal collar, and twist out of the handpiece. A
twisting motion is recommended as the best way of removing and
inserting scaler tip inserts through the internal handpiece sealing O ring.
b. Shake the Handpiece to remove coolant liquid.
c. Insert new scaler tip insert with a twisting motion until fully seated.
CAUTION: Avoid contact with temporary restorations, or porcelain crowns.
Avoid contact with the tongue or mucosa with the un-cooled part of the tip.
8. Life expectancy of the scaler Tip. As the tip wears, due to use, the
efficiency will be reduced. If performance is reduced, check that the Ferrite
Rod (7) is tight and that no foreign matter is in the handpiece. A loose ferrite
rod is the most common cause of poor tip efficiency. Change the ferrite rod to
see if an improvement can be gained – If no improvement is found, a new tip
is indicated. Tip wear can be reduced by the use of CLS, as it contains
glycerin, which will help lubricate the tip and reduce tip wear.
Instrument tips that are bent, or scratched should be discarded immediately.
Do not think the “jack hammer” of other scalers improves efficiency. The 42-
12 operates by using ultrasonic frequency, along with mechanical movement
to remove and breakdown calculi. The Ultrasonic sound will also destroy the
cell wall of bacteria within a 1 to 2mm proximity, promoting improved dental
mouth hygiene in your patients, particularly in deep sub-gingival pockets. The
use of CLS with its chlorhexadine will further improve the disinfecting of such
gingival pockets.
