Buffered oxide etch is commonly used for more controllable etching. [1] Buffering HF with NH 4 F results in a solution with a more stable pH; thus, more stable concentrations of HF and HF − 2, and a more stable etch rate. [2] Some oxides produce insoluble products in HF solutions.
Penetrating sealers often require the use of special cleaners which both clean and top up the repellent ingredient left on the stone surface. These sealers are often breathable to a certain degree, but do not penetrate deeply enough (generally less than 1mm) to be effective against salt attack, such as efflorescence and spalling.
Resin sealants require a phosphoric acid solution ("etch") to create microscopic porosity into which the sealant material can flow thereby increasing retention, increasing surface area and improving the strength of the bond between the sealant and the tooth surface. [28] Etching time varies from 15 to 60 seconds, depending on the product.
All-in-one self-etch adhesive and a single component universal adhesive, used in the adhesion of direct and indirect dental restorations. Also known as a "bonderizer" bonding agents (spelled dentin bonding agents in American English) are resin materials used to make a dental composite filling material adhere to both dentin and enamel.
Adhesive dentistry is a branch of dentistry which deals with adhesion or bonding to the natural substance of teeth, enamel and dentin.It studies the nature and strength of adhesion to dental hard tissues, properties of adhesive materials, causes and mechanisms of failure of the bonds, clinical techniques for bonding and newer applications for bonding such as bonding to the soft tissue.
