About etching agents
The etchant of the total-etch technique is 35 to 37 percent phosphoric acid, which creates microscopic pores in enamel and dentin for the resin to lock into. Glass-based ceramics need a stronger medium than phosphoric acid: hydrofluoric acid, which dissolves the glass in the ceramic.
A bonding agent is a resin painted onto the inside of a prepared tooth to improve the retention of a restoration such as a filling. The FDA regulates it as a resin tooth bonding agent, a Class II device (21 CFR 872.3200). An etchant is a chemical agent that selectively dissolves a surface, leaving it retentive.
Bonding to teeth follows an etch-and-rinse or a self-etch strategy; resin-modified glass ionomer, which adheres on its own, is counted as a third. Retention comes from a hybrid layer and resin tags formed when the adhesive hardens inside the etched surface.
How the types of adhesive and etchant differ
- Universal adhesives — One adhesive for any of the three etching approaches. The makers of some still call for a separate activator or a dedicated primer on porcelain and zirconia.
- Self-etch adhesives — No separate acid and no rinsing. It does not etch enamel to the depth phosphoric acid does.
- Total-etch adhesives — Applied after phosphoric acid that is rinsed away. A review calls the three-step systems the most versatile, usable with self-cure, dual-cure and light-cure protocols.
- Etching agents — The acid itself: phosphoric acid for enamel and dentin, hydrofluoric acid for glass-based ceramics.
- Ceramic primers and silane — Prepares the ceramic restoration, not the tooth, for bonding.
- Adhesive accessories — The applicators that carry the adhesive to the tooth.
What to look at when choosing a bonding agent
Bottles and steps: systems run from three bottles to one. A review reports the highest bond strengths for the three-step systems, which are also the most complicated to use.
Compatibility: not all one-bottle etch-and-rinse adhesives are compatible with self-cured or dual-cured materials or with core materials.
Delivery: self-etch adhesives come in bottles or unit doses, and two-part ones are mixed immediately before use.
For ceramics: a systematic review found better bonding when silane was applied separately than when it was only contained in a universal adhesive.
Testing: ISO 29022 describes the shear test used to measure the bond strength between restorative materials and tooth structure.
