Abstract
Methods and compositions including an aqueous liquid that includes an acid-sensitive dye are disclosed for use in dental and orthodontic procedures. The aqueous liquid can be useful for providing a visible color change to indicate contact with acidic materials including, for example, etching compositions, self-etching adhesives, and self-adhesive compositions.
Claims43
A method of bonding a dental material to a dental structure, the method comprising:
- wetting a surface of a dental structure with a liquid comprising an acid-sensitive dye and water;
- applying a self-etching adhesive to at least a portion of the wet dental structure surface under conditions effective to cause a visually observable color change before hardening in the portion of the dental structure surface having the self-etching adhesive applied thereon;
- drying the dental structure surface to form an adhesive layer thereon;
- applying a dental material to the dental structure surface having the adhesive layer;
- and
- hardening at least one of the adhesive layer under conditions effective to form a bond between the dental material and the dental structure.
A method of restoring a dental structure, the method comprising:
- wetting a surface of a dental structure with a liquid comprising an acid-sensitive dye and water;
- applying a self-adhesive composition to at least a portion of the wet dental structure surface under conditions effective to cause a visually observable color change before hardening in the portion of the dental structure surface having the self-adhesive composition applied thereon;
- and
- hardening the self-adhesive composition under conditions effective to form a bond between the hardened composition and the dental structure of at least 7 MPa.
A method of adhering an orthodontic appliance to a tooth, the method comprising:
- wetting a surface of a tooth with a liquid comprising an acid-sensitive dye and water;
- applying a self-adhesive composition to at least a portion of the wet tooth surface under conditions effective to cause a visually observable color change before hardening in the portion of the tooth surface having the self-adhesive composition applied thereon;
- applying an orthodontic appliance to the tooth surface having the self-adhesive composition applied thereon;
- and
- hardening the self-adhesive composition under conditions effective to form a bond between the orthodontic appliance and the tooth.
A method of adhering an orthodontic appliance to a tooth, the method comprising:
- wetting a surface of a tooth with a liquid comprising an acid-sensitive dye and water;
- applying an orthodontic appliance having a self-adhesive composition thereon to at least a portion of the wet tooth surface under conditions effective to cause a visually observable color change before hardening in the portion of the tooth surface having the orthodontic appliance and self-adhesive composition applied thereon;
- and
- hardening the self-adhesive composition under conditions effective to form a bond between the orthodontic appliance and the tooth.
A method for applying a composition to a dental structure, the method comprising:
- wetting a surface of a dental structure with a liquid comprising an acid-sensitive dye and water;
- and
- applying a composition to at least a portion of the wet dental structure surface under conditions effective to cause a visually observable color change before hardening in the portion of the dental structure surface having the composition applied thereon, wherein the composition is a self-etching adhesive, a self-adhesive composition, or a combination thereof.
