Vista Apex specifically engineered 17% EDTA with a LOWER pH for optimal performance! For best outcomes, a LOWER pH is more important than concentration. As pH increases, the availability of calcium ions from hydroxyapatite for chelation decreases. A pilot study using concentrations of alkaline (pH 11.3) solutions of EDTA showed them to be less effective in removing the smear layer.

Vista Apex’s EDTA:

• Prepares dentin walls for better ADHESION of filling materials
• Opens dentin tubules
• Removes smear layer and dentin mud
• Enhances cleansing

The optimal pH for EDTA solutions should be between 7.5 – 9
