Manual and mechanical stripping-induced enamel roughness and elemental composition in vivo.

Objectives: Interproximal enamel reduction (IPR) is routinely used in orthodontics to generate small to moderate amounts of space within the dental arch. Aim of this ex vivo study was to evaluate the effect of two different IPR systems on the enamel surface's waviness, roughness, and elemental composition after 6 months of intraoral exposure.

Materials And Methods: Fifteen orthodontic extraction patients were included in the present study.
