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.
