Table 3C.
The quantity of eluted TEGDMA monomer from three composite resins after incubation in three different solutions. Mean TEGDMA release (μg/mL) from composite resins samples was measured after 1 h, and 1, 3, 7, 14 and 21 days. Means with same superscript symbol do not differ significantly. The others means show statistically significant (P<0.05, P<0.01) differences.
