The ideal goal of periodontal instrumentation is to effectively remove plaque
and calculus without causing root surface damage and various instruments have been designed to achieve
this goal. Root planing aim to create a root surface which is biolo
gically acceptable to surrounding soft
tissues and increase root surface roughness.
Aim of study: To evaluate the increasing of root surface roughness produced by hand curettes and
piezoelectric ultrasonic instrument with different power settings .
