Quantitative Evaluation by Glucose Diffusion of Microleakage in Aged Calcium Silicate-Based Open-Sandwich Restorations

Table 3

Glucose concentration in the receiving medium after 1 h diffusion through the gingival margin of open-sandwich restorations filled with a calcium silicate-cement or a resin-modified glass ionomer cement. A statistically significant difference was found among the four groups. The groups with the same superscript letter were not statistically different.

Material	Glucose concentration (g/L)
Calcium silicate cement	0.074 ± 0.035^b
Resin-modified glass ionomer cement	0.080 ± 0.032^b
Positive control	0.450 ± 0.320^c
Negative control	0 ± 0.002^a
