Assessment of
salivary and urinary
concentration of
BPA after RBC
placement
In vivo study on urine
samples followed by
analysis using Liquid
chromatography/mass
spectrometry
BPA levels in urine
levels following
sealant placement,
have shown an
increase in urine
BPA for upto 30 h
Kingman et al. [31]
7
Identification and
characterization of
microplastics in
toothpaste and
personal care
products
Identification using
particle analysis
software image J 1.51
and composition by
FTIR
Found LDPE type
MPs in the
concentration of 7%
in the sample tested
Praveena et al. [42]
8
Assessment of
weathering impact
and uptake of
polyethylene
microplastics from
toothpaste in
mussels
Mussels where
exposed to
Polyethylene (PE)
extracted from
toothpaste
100 ml of a popular
toothpaste brand and
extracted 100 mg of
polyethylene MPs
PE particle ingestion
resulted in structural
changes to the gills
and digestive gland,
as well as necrosis in
other tissues such as
the mantle
Bråte et al. [7]
9
Assessment of
interaction of
microplastics
derived from
toothpaste with four
types of bacteria
Study
on Microplastics
extracted from
commercially
available toothpaste
samples interacted
with four types of
bacteria under both
standard and seawater
conditions
Biochemical
responses were
similar in both
media, the difference
between the cell wall
and microplastics
surface charge was
important only in
seawater
Ustabasi and Baysal
[56]
10 To identify the
relation between
usage of dental
amalgam and
psychosocial
problems
Conducted a
randomized trial
among children of age
group 6–10 years
Study has shown a
reflection of the
harmful effects of
resin based
composites as they
had shown
detrimental effects to
the children behavior
compared to
amalgam group
