summary Conventional glass‐ionomer cements with varying amounts (5–15%) of borax (Na 2 B 4 O 7 .10H 2 O) as modifier were prepared. These mixtures were spatulated with an aqueous solution of polyacrylic acid with a powder to liquid (P/L) ratio of 1.5:1. Properties such as working time, setting time, compressive strength, diametral tensile stength, solubility and fluoride release of these cements were determined. It was observed that the working time and setting time of the resultant cements shortened with the addition of borax. Certain physical properties such as compressive and diametral tensile strength, solubility and disintegration of these glass‐ionomer cements deteriorated with borax addition but fluoride release from them was unaffected.
