  1. Here is one small study that disagrees .....

    Long-term clinical evaluation of fracture and pulp injury following
    glass-ionomer cement or composite resin applied as a base filling in
    teeth restored with amalgam.

    The aim of this research was to analyse the long-term clinical
    behaviour of two dental materials applied as filling under silver
    amalgam restorations: glass-ionomer cement (GIC) and composite resin
    with adhesive system (CR). In this study, 117 posterior teeth (29
    premolars and 88 molars) were selected with carious lesions which
    resulted in great loss of dentin and cusps with unsupported enamel.
    After caries removal, cavities were prepared and totally filled with
    GIC or with CR. In a following visit, new cavities were prepared,
    leaving the employed filling material as a base and support for the
    enamel, which were then restored with silver amalgam. Restorations
    were evaluated periodically after 6 months and up to 5 years. Both
    fracture and pulpal involvement rates were low. Although differences
    could be observed in the behaviour of the materials, statistical
    survival estimation showed that the performances of GIC and CR as
    filling material were similar. There was a significant association
    both between kind of tooth (molar or premolar) and long-term survival
    of the restorations; and between degree of unsupported enamel and the
    same long-term survival. Our results confirmed that the technique in
    which GIC or CR are used as filling under silver amalgam restorations
    is clinically acceptable.
