Effect of Surface Sealants and Polishing Time on Composite Surface Roughness and Microhardness

Operative Dentistry, 2018
SUMMARY The objective of this study was to evaluate the effect of surface sealants and polishing delay time on a nanohybrid resin composite roughness and microhardness. Eighty disc specimens were made with a nanohybrid resin (Esthet-X HD, Dentsply). The specimens were divided into two groups (n=40) according to polishing time: immediate,
