Microabrasion for removal of local stains on teeth utilizes 18% hydrochloric acid. This technique involves: 1) Application of 18% hydrochloric acid mixed with pumice to create an abrasive paste, 2) The acid etches the enamel surface while pumice provides mechanical abrasion, 3) This removes superficial enamel layer containing stains (typically 25-200 micrometers), 4) Effective for fluorosis stains, white spot lesions, and superficial discolorations. The procedure requires careful isolation and neutralization to prevent tissue damage.

Electralloy is an alloy of electrolytic gold and calcium, typically with a calcium content of 0.1-0.5%. The addition of calcium creates a dispersion-hardened material that is stronger than pure gold. This property makes it suitable for use in restorations requiring increased hardness and wear resistance, such as inlays and onlays.
