Resumo
1) Introduction: The combination
between high power lasers
and fluoride may potentially
control the progression of dentin
erosion. Therefore, the aim of this
study was to evaluate the effect
of Er,CrYSGG laser, associated
to fluoride application, in the
control of dentin erosion.
2) Materials and Methods: Dentin
slabs were embedded into acrylic
resin, flattened and polished.
The specimens (n=10) were previously
eroded (10min immersion
in 1% citric acid solution) and
randomly allocated into the
experimental groups, according
to the following treatments:
control (no treatment); acidulated
phosphate fluoride (APF) gel
(1.23% F, 1min); Er,Cr:YSGG laser
irradiation (parameter 1: 0.25W,
20Hz, 2.8J/cm2); Er,Cr:YSGG
loser irradiation (parameter 2:
0.50W, 20Hz, 5.7J/cm2); APF
gel+Er,Cr:YSGG laser parameter
1 and; APF gel+Er,Cr:YSGG
laser parameter 2. After, they
underwent on erosion-remineralization
cycling, consisting
of a 5min immersion into 0.3%
citric acid, followed by 60min
exposure to artificial saliva. This
procedure was repeated 4x/day,
for 5 days. Surface loss (SL, in
μm) was determined with optical
profilometry. The specimens
were analyzed by environmental
scanning electron microscopy
(n=3). Data were statistically
analyzed (α=0.05).
3) Results: None of the groups
significantly differed from the
control group, except for the
APF group. APF gel presented
the lowest SL, not differing from
Er,Cr.YSGG laser (parameter 1)
and APF gel+Er,Cr:YSGG laser
(parameter 1). Selective structure
removal was observed for the
laser-treated groups.
4) Conclusions: None of the
Er,Cr:YSGG laser parameters
were effective in the control of
dentin erosion. The laser was
also not able to enhance the
protection of fluoride against
dental erosion.
