This study was done to evaluate the changes of enamel surface by interproximal stripping and recovery of it by polishing. The number of 34 1st premolars which had extracted for orthodontic treatment were selected as samples. Interproximal stripping was performed by hand with metal strip and strip placer (Dentaurum Co., Germany) and low speed handpiece with diamond disk (Superdiaflex, Germany). Polishing was performed by hand with plastic strip (3M Col) and low speed handpiece with whip-mix, DCPA (Dicalcium Phosphate, Anhydrous, CaHPO₄) powder and Sof-lex (3M Co. U.S.A.) polishing kit. Each groups were examined under the scanning electron microscope (JEOL Co., JSM-840A, Japan) and the following results were obtained: 1. The stripped group performed by metal strip and diamond disk altogether showed deep furrow on the enamel surface as wide as about 10µm. 2. There could be seen more irregular scratched line in the group stripped by metal strip than that by diamond disk. 3. The polished group performed by plastic strip and DCPA powder showed slight smoothening of the edge of stripped furrow on the enamel surface without relation to the stripping method. 4. The polished group performed by Sof-lex progressive polishing kit could not avoid the formation of the furrows on the enamel surface according to the particle size without relation to the stripping method. 5. The polished group performed by the superfine polishing wheel, the final stage of Sof-lex polishing method showed shallow scratched line as wide as within about 2µm on the enamel surface without relation to the stripping method. 6. The interproximal stripped enamel surface could not recover its original surface texture by any kind of polishing methods.
