Implication

In vitro study evaluates surface properties in composite resins with different photo-initiators, suggesting the impact of polishing systems.

Key Points

The aim is to assess how different photo-initiators and polishing systems affect the surface roughness and microhardness of composite resins.
Conducted an in vitro study with 60 composite resin samples categorized by photo-initiator and polishing system.
Used two polishing systems: Shofu One Gloss (single-step) and Astropol (multi-step).
Measured surface roughness with a profilometer and microhardness using a Vickers hardness tester.
IPS Empress Direct exhibited significantly lower surface roughness and higher microhardness than 3M ESPE Filtek Z250XT.
Astropol multi-step polishing system outperformed Shofu One Gloss in improving surface properties.
Statistical significance was achieved (p < 0.05) for the differences observed.
