Purpose: To evaluate the relationship between degree of conversion and microhardness of a composite based on silorane monomers (Filtek P90-3M ESPE). Methods andmaterials: The specimens (n=10/gp, cylindrical 5mm× 2mm, light-cured 1100mW/cm2) were divided into 5 groups according to the energy amount obtained by the variation in the irradiation time (8, 12, 16, 20 and 24 J/cm2). The DC was performed using a FTIR (Excalibur 3100) and ATR (Miracle) in real time. Sixteen scans of spectra were performed (4cm−1/20min). The Knoop Hardness Number (KHN) was performed (Durimet) in a total of 10 indentations/specimen bottom (30 s/25 g). The data were tested for normality and homogeneity and then subjected to ANOVA (5%). Results: The data were presented on table. DC: p=0.324; KHN: p |
