Effect of Different Scaling Methods on Surface Roughness, Color Stability and Bacterial Accumulation of Lithium Disilicate Ceramic
Fatma Mostafa Makkeyah;
Abstract
The current study evaluated the effect of different scaling methods on surface roughness, color stability and bacterial accumulation of lithium disilicate ceramic.
Seventy disc shaped IPS e.max Press samples; were constructed using the lost wax technique.
The samples were divided according to the scaling method into three groups:
Group I: Control, No scaling (10 samples)
Group II: Manual scaling (30 samples)
Group III: Ultrasonic scaling (30 samples)
Then the manual and ultrasonic groups were further subdivided according to the material of the scaling instrument into 3 subgroups:
A) Stainless steel
B) Titanium
