摘要：

The in vitro reactivity of different glasses, with 55mol% SiO2 and MgO/Na2O molar ratios ranging from 1/8 to 8/1, was investigated. Despite the same amount of SiO2, the glasses exposed different reactivities, from very reactive (low MgO/Na2O ratio) to inert (high MgO/Na2O ratio). These results are interpreted in terms of a cross-link disruption by Na2O.
