Effect of Surface Sealants and Polishing Time on Composite Surface Roughness and Microhardness [PDF]

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,
