Abstract

Objective The aim of the present study was to investigate aliphatic C=C bonds on surfaces of FRC posts by micro ATR-FTIR spectroscopy. Materials and methods Fiber posts were determined aliphatic C=C bonds on post surface by micro ATR-FTIR spectroscopy using mid infrared (4000-600 cm-1). The contact area between germanium crystal and fiber post was 100 μm in diameter circular shape. The spectrum was acquired at 1 μm depth from post surface. Wavenumbers and transmittance were recorded in each fiber post. The aliphatic C=C bonds were analyzed from peaks of spectra compared with reference wavenumbers. Results The peak height of aliphatic C=C bonds at 1638-1636 and 1637-1632 cm-1 were investigated on post surface of FRC Postec Plus® and FibreKleer® Tapered post which these were not shown on surface of DT Light post® and RelyXTM fiber post. Conclusion Aliphatic C=C bonds were present on surfaces of FRC Postec Plus® and FibreKleer® Tapered post.
