Enamel surface roughness of preferred debonding and polishing protocols.

Objective: This study investigated the surface roughness of enamel after debonding and instrumentation with commonly used methods.

Methods: Part I: a survey was sent to active members of the American Association of Orthodontists to determine popular bonding, debonding, and polishing protocols. Part II: brackets were bonded to the buccal surface of 30 extracted human premolar teeth.
