In vitro FT-IR study of the effects of hydrogen peroxide on superficial tooth enamel.

Objectives: The aim of the present study was to determine the alteration in human enamel after hydrogen peroxide treatment using FT-IR spectroscopy. It is hypothesized that infrared spectroscopy is capable of showing alterations in human enamel after peroxide treatment and the alteration in enamel is proportional to peroxide concentration.

Methods: The effects of 10, 20 and 30% hydrogen peroxide solutions on human enamel were tested.
