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

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
