Infrared spectroscopy: a tool for determination of the degree of conversion in dental composites

J Appl Oral Sci. 2008 Mar-Apr;16(2):145-9. doi: 10.1590/s1678-77572008000200012.

Abstract

Infrared spectroscopy is one of the most widely used techniques for measurement of conversion degree in dental composites. However, to obtain good quality spectra and quantitative analysis from spectral data, appropriate expertise and knowledge of the technique are mandatory. This paper presents important details to use infrared spectroscopy for determination of the conversion degree.
