DEN
TAL ASSISTING
an ultrasonic instrument with a tip for supplying high-frequency vibrations
used to remove plaque and calculus from teeth and bits of inflamed tissue from the walls of the gingival crevice.

TAL ASSISTING
1. Magnetostrictive - pattern of vibration is elliptical- all sides of the tip are active
2. Piezoelectric - vibration is linear- two sides of tip are active

3 Typical Manual Scaler Parts
a. Blade or Nibb. Shankc. Handle
ADVANTAGES
Sharpening not required Easier to debride inaccessible furcations Less tissue distention Reduce operator fatigue
DISADVANTAGES
Water control Evacuation needed Production of contaminated aerosols Potential occupational hazard
(noise/vibration) Requires power supply

Terms Debride / Debridement – refers to the necessary
palque calculus that have accumulated on the teeth.Distention – to swell out/ expand from or as of
from internal pressure Furcation – the anatomical area of a multi-rooted
tooth where the roots devide Tenacious – hard to remove Traction – a pulling force exerted on a skeletal
structure (tooth) by means of a special device or apparatus
