HIGHLIGHTS
- who: Competing interests No competing and colleagues from the Education, Manipal, Karnataka, India have published the research work: Effect of vital bleaching on surface roughness and microhardness of nanofilled and nanohybrid composite resins [version 1; peer review: awaiting peer review], in the Journal: (JOURNAL)
- how: The experiment was carried out in triplicate on each disc and average surface roughness as Ra was recorded in microns.
SUMMARY
Computation of hardness. The surface hardness was calculated by dividing the load by the area of the indention and was reported as Vickers hardness number . . .
