A comparison of traditional orthodontic polishing systems with composite polishing systems following orthodontic debonding.

Introduction: At the completion of treatment, the orthodontic practitioner's goal is to effectively remove all traces of adhesive and return enamel to its initial state. With the advent of new polishing systems being released each year, there may be one product that is superior to others.

Aim: The purpose of this study is to determine the efficacy of new polishing systems (in the last 5-10 years) used in general dentistry on enamel surface roughness following debond utilizing profilometery and scanning electron microscopy and compare them to established orthodontic polishing systems results.

Nickel and chromium ion release from coated and uncoated orthodontic archwires under different pH levels and exposure times.

Objectives: The purpose of this study was to determine and compare nickel and chromium ion release from traditional stainless steel and nickel titanium wires and newer esthetic archwires under different pH conditions, for different time intervals.

Methods: Ten pieces of 10-mm segments of five different orthodontic archwires were submerged in buffer solutions of pH 4.0, 5.
