Erosion Process of Polycarboxylate Cements in Organic Acids
Dental Materials Journal, 1983 The amounts of Zn and Mg eluted from the zinc polycarboxylate cement into acetic, lactic and citric acids increased with an increase in the formation constant of the acid-Zn or -Mg complexes. The erosion process consisted of two processes, namely, dissolution of the unreacted cement powder and decomposition of the matrix.

Effect of Aluminoborate Whiskers on Mechanical Properties of Polycarboxylate Cements
Dental Materials Journal, 2008 The mechanical properties of polycarboxylate cements containing 20 mass% of four kinds of aluminoborate whiskers with different fiber lengths and diameters were evaluated. Bending strength of the cements increased with increase in fiber length, whereby the strength of the cement with the longest fiber was about two times greater than that of whisker ...
