Pulpdent Etch-Rite 38% Phosphoric Acid Dental Etching Gel is used for the acid-etching step of the total-etch and selective-etch adhesive bonding protocol in composite resin restorations, porcelain and ceramic bonding procedures, orthodontic bracket bonding, and other restorative and esthetic procedures. The phosphoric acid gel is applied to prepared enamel and dentin surfaces to remove the smear layer, open dentinal tubules, and create the micro-retentive etch pattern that the bonding adhesive penetrates to form the hybrid layer and resin tags needed for micromechanical adhesion. Each pack contains 24 syringes.

Dental offices ordering etching gel from their supplier can buy this bulk configuration for high-volume restorative and bonding practices, since the 38% phosphoric acid concentration provides effective etching of both enamel and dentin at recommended contact times without the over-etching risk associated with concentrations significantly above the optimal range for total-etch protocol adhesive bonding. The thixotropic soft gel formulation is the key physical property distinguishing Etch-Rite as a precision etching gel: the gel is viscous and stable when undisturbed in the syringe but becomes more fluid when shear force is applied during extrusion, allowing it to be extruded smoothly through small-gauge pre-bent applicator tips before resuming its gel body immediately upon placement on the tooth surface. Once placed, the gel holds its position on enamel and dentin without flowing onto adjacent gingival tissue or oral mucosa during the etch contact time, recommended at approximately 15 seconds for dentin and 20 seconds for enamel, and it washes off completely with water spray afterward, leaving no residue that would interfere with adhesive penetration or require additional cleaning steps before bonding.
