The purpose of this study was to compare marginal leakage in Class V preparations restored and finished within 20 minutes with two different capsulated and syringeable restorative glass ionomer cements. The materials were inserted and finished following manufacturer's specifications. Specimens were thermocycled 125x in fuchsin dye at 5 degrees C and 55 degrees C, mounted in acrylic and sectioned faciolingually. Microleakage was observed and rated on a scale of 0 to 3 at both enamel and cervical margins. The results of this study indicate that: 1) both materials exhibit marginal leakage at enamel and cervical margins, 2) no significant difference in microleakage was found between these materials, and 3) enamel margins leaked less than cementum/dentin margins with each material.
