Analysis of Physical and Mechanical Properties of Universal Composites under Different Types of Polishing before and after Acid Challenge
Table 2
Identification of groups, polishing protocols, and challenges.
Groups (for each composite) n = 240
Polishing protocols
Challenges (subgroups)
CWP Positive control
Without polish—Specimens were not subjected to finishing/polishing procedures after light-curing under polyethylene strip n = 20
Artificial saliva n = 10 or HCl 5% n = 10
CW Negative control
With wear—The top surfaces of the specimens were ground with a conical diamond tip 3195 FF, with air/water cooling, for 10 s, obtaining 0.3 mm of wear n = 20
WPC Wear + polish with Cosmedent Kit
Wear with FG 3195 FF + polishing with medium-grained siliconized cups (blue color), extra-fine grain (pink color), and spiral-shaped diamond wheel for high brilliance, diameter 1/2" (pink color) n = 20
