Intended Use

The principle uses of the Bisco Etchants are: - 1. Etching and cleaning of dentin and enamel - 2. Cleaning of restorative surfaces prior to bonding

Device Story

Bisco Etchants are phosphoric acid semi-gels used in dental procedures. The device is applied by a dental professional to tooth surfaces (dentin and enamel) or restorative materials. The phosphoric acid acts to remove the smear layer, demineralize the surface, and expose dentin tubules, creating a microretentive surface. This process prepares the tooth or restorative surface for the application of bonding agents. The device is used in a clinical dental setting to improve the efficacy of subsequent restorative bonding procedures.

Clinical Evidence

No clinical data. Substantial equivalence is based on chemical properties and performance characteristics demonstrating the ability to clean and demineralize tooth surfaces.

Technological Characteristics

Phosphoric acid semi-gel. Chemical composition and concentration are consistent with established dental etching agents. No electronic, software, or mechanical components.

Indications for Use

Indicated for etching and cleaning of dentin and enamel, and cleaning of restorative surfaces prior to bonding in dental patients.

Regulatory Classification

Identification

A resin tooth bonding agent is a device material, such as methylmethacrylate, intended to be painted on the interior of a prepared cavity of a tooth to improve retention of a restoration, such as a filling.
