EtchArrest dual-purpose acid barrier/neutralizer is applied before etching to protect adjacent hard and soft tissues and existing restorations. Use it to neutralize porcelain etch before removal to prevent acidic splatter. It is viscous enough to not run on vertical surfaces, yet it can still flow into tiny irregularities.
- Neutralizes acid etchants upon contact
- Protects soft tissues and adjacent restorations
- Appears visible against tissues and acid etching agents
- Viscous texture allows for precise placement
- Rinses easily
Protects Bond Strengths During Porcelain Repair Procedures
When hydrofluoric acid contacts enamel during porcelain repair procedures, formation of calcium fluoride occurs and bond strengths to enamel drop significantly.1 Therefore, it is vital to treat porcelain and tooth structure separately with appropriate acids. EtchArrest neutralizer isolates hard and soft tissues when rubber dam placement is not practical.
Neutralizes Etchants on Contact
EtchArrest neutralizer contains sodium bicarbonate and calcium to neutralize the acids in etchants. This allows EtchArrest neutralizer to create a protective barrier around the area needing to be etched, and to easily neutralize the acids when etching time is reached.
Protects Soft Tissues and Nearby Restorations
Nearby teeth and gum tissue should always be covered when using acids. The viscous, acid-neutralizing EtchArrest ensures that nearby tooth structure and membranes remain protected during the etching process.
EtchArrest neutralizer features a dark purple tint that is easily seen against both etchants and mouth tissues.
When EtchArrest neutralizer is mixed with etchant, the acids in the etchant are neutralized. This allows you to clean the mixture out of the mouth without fear of spraying acids onto delicate tissues. The mixture is easily rinsed off with water.
Using EtchArrest neutralizer during porcelain restorations
EtchArrest acid barrier/neutralizer protects adjacent porcelain and soft tissue from hydrofluoric acid. For situations where dentin/enamel are present in a preparation, use Ultra-Etch™ etchant phosphoric acid first to etch the tooth, then hydrofluoric acid second to etch the porcelain. This will ensure that dentin/enamel bond strengths are not compromised. Hydrofluoric acid will reduce adhesion to dentin and enamel, so EtchArrest neutralizer prevents accidental migration onto tooth structure.
Frequently Asked Questions
When should EtchArrest neutralizer be used?
EtchArrest neutralizer is used to protect hard and soft tissues when dam placement is not practical or possible. It should be also be used with Porcelain Etch in order to neutralize the hydrofluoric acid before rinsing to ensure safe removal.
When would rubber dam placement not be practical?
When etching a very small area, EtchArrest neutralizer can be used to create a barrier to protect nearby tooth structure, gingival tissue, and restorations.
How does EtchArrest neutralize the etchant?
EtchArrest neutralizer contains sodium bicarbonate and calcium to neutralize the acids in etchants. When the desired etching time has been reached, simply mix the EtchArrest with the etchant to stop etching.
How does EtchArrest neutralizer assist in cleanup?
Since EtchArrest neutralizes the etchant when they are mixed together, you can rinse the mixture away without fear of acidic spray hurting the patient. The dark hue of the product also ensures that you can easily see that the mixture is completely rinsed out of the mouth.
