Surface hardness measurements of bis-acrylic resins under different conditions

This dataset contains Rockwell hardness measurements (HRA) of two bis-acrylic resins, 3M ESPE Protemp™ 4 and FGM Primma Art, tested under two different conditions: moist and dry after seven days. A total of 40 samples were analyzed, with 10 samples per condition. The data include minimum, maximum, mean hardness values, and standard deviations. Statistical analyses, including Shapiro-Wilk, Levene’s test, and Student’s t-test, were performed to compare groups.
