1
Quantitative
characterization of
the bisphenol-A
(BPA) released from
orthodontic
adhesives after
artificial accelerated
aging
In vitro assessment of
the release of BPA
after various time
intervals of 1 day, and
weekly intervals of
1,3 and 5 weeks from
chemically cured,
no-mix adhesive and a
visible light-cured
adhesive bonding
agents
BPA release from
light-cured or
chemically cured,
no-mix adhesives did
not reach the 0.1
ppm level
Eliades et al. [18]

To assess the
bisphenol A (BPA)
released from an
orthodontic adhesive
with various light
curing tip distances
In vitro assessment of
BPA released from
orthodontic adhesive
at light curing tip
distances of 0, 5 and
10 mm using Fourier
transform infrared
spectroscopy
BPA release was
greater in specimens
cured with a greater
light-curing tip
distance
Sunitha et al. [49]

Comparison of
estrogenicity of heat
cured and light cured
dental adhesives
which were
collected during the
debonding process
of fixed orthodontic
appliances
In vitro assessment of
the influence of
eluents from the
solution of two type of
adhesives to estrogen
responsive cell line
BPA in self cured
resins increased the
proliferation of
MCF-7 breast cancer
cells by 160% while
there was a 128%
increase by BPA
released from light
cured resin adhesives
Gioka et al. [23]

Identification and
quantification of
microplastics in
tooth paste
Particles were
quantified and then
characterized by
microscopic
evaluation and surface
chemistry analysis
4 out of 20 samples
showed the presence
of polyethylene type
MPs in the
concentration range
of 0.4–1%
Ustabasi and Baysal
[55]
5
Identification and
quantification of
polyolefins in tooth
paste
Quantitation with
high-temperature
gel-permeation
chromatography
Identified the
presence of 0.17% of
polyethylene type
MPs in a single
sample they tested
Hintersteiner et al.
[28]

the field of dentistry to assess the use of microplastics in dentistry, toxicity level of
various composite resins being used and the impact of them on environment and
human.
