The etching of the dentin surface even for a short time can lead to significant changes in the dentin structure. It must be efficient, not extensive . In extensive demineralization of the intertubular dentin the collagen fibers will collapse and the calcium phosphate crystals will precipitate and therefore a protective layer that may not be completely impregnated by the adhesive primer and monomer could be formed.
37% wt phosphoric acid etchant for enamel and dentin. Easily controlled gel flows under direction, not under gravity.
30 to 40% wt phosphoric acid optimally etches in 15 to 20 seconds. Lower concentrations require longer contact time, unnecessarily delaying procedures.
Non-slump gel offers precise placement around the specific area where we need to do the light cure restoration
High visibility for precise placement, even in the inaccessible areas of the oral cavity like distal surfaces of maxillary tooth
