Abstract
Statement of problem
The corrosive effects of oral fluoride products on titanium have been reported, and
chronic fluorosis, which causes hyperfluoemia, is one of the world's health problems.
Nevertheless, the relationship between high serum fluoride and corrosion on the titanium
surface, which might have adverse effects on titanium implant osseointegration, has
not been elucidated.
Purpose
The purpose of this in vitro study was to investigate the corrosion behavior of pure
titanium exposed to high serum fluoride with different pH values based on surface
analysis.
Material and methods
Pure titanium specimens, exposed to different electrolytes with 0.04 and 0.4 ppm NaF
at pH 7.3 and 5.0 values, were examined for surface microstructure by using scanning
electron microscopy (SEM) and for surface element composition with X-ray photoelectron
spectroscopy (XPS). The corrosion behavior and metal ion release of specimens immersed
in the Hanks’ balanced salt solution (HBSS) containing 0.04 and 0.4 ppm serum fluoride
concentrations (NaF) at 7.3 and 5.0 pH values were measured by electrochemical impedance
spectroscopy (EIS) and inductively coupled plasma atomic emission spectrometry (ICP-AES).
Results
Pitting holes were observed on pure titanium surfaces exposed to high serum fluoride.
The surfaces became rougher with the increase of serum fluoride concentration, especially
under acidic conditions. XPS analysis revealed a reduction of dominant titanium dioxide
(TiO2) on the pure titanium surface under serum fluoride exposure, corresponding to an
increase in the relative level of F. EIS data showed an active corrosion behavior
of pure titanium exposed to high serum fluoride and gradually decreased corrosion
resistance with increasing concentration of serum fluoride, which was more severe
under acidic conditions. The release of titanium ions was also induced by high serum
fluoride and acidic conditions.
Conclusions
High serum fluoride had a negative influence on the corrosion behavior of pure titanium.
The titanium oxide film barrier could be broken down in the fluoride ions condition,
and the corrosion resistance of pure titanium decreased with the increasing concentration
of serum fluoride. The increased corrosion susceptibility of pure titanium accelerated
the release of titanium ions after exposure to high serum fluoride; this was more
pronounced in an acidic environment.
