Polishing
60 nm silica nanoparticles
A component of
slurry to make
dentinal surface
smoother
Streptococcus mutans
bacteria could be easily
removed on the smooth
silica particle coated
surface

21 nm silica nanoparticles
The effect of silica
nanoparticles by
themselves
Silica nanoparticles
reduced the attachment
and growth of C.
albicans
[49]
220 and 510 nm
silica
A chlorine-ion
source
Increased bacteria
killing by releasing N-
halamine-functionalized
particles
[50]
polymer core-shell
nanoparticles
30 nm flame-derived bioactive
glass 45S5
Comparison of
antimicrobial effect
between nano-
and micron-sized
bioactive glasses
Micron-sized glass did
not show any
antibacterial effect, but
the nanosize was
decreased in
Enterococcus faecalis
cells after direct
exposure
[51]
90 and 136 nm NO-release
silica nanoparticles
Antimicrobial effect
of NO-release
silica nanoparticles
The NO-release
nanoparticles killed over
99% of cells from each
type of biofilm,
Pseudomonas
aeruginosa, Escherichia
coli, Streptococcus
aureus, Staphylococcus
epidermidis, and
C. albicans
[52]
Filler
26 nm silica and bis-GMA/
TEGDMA polymer
A filler to enhance
mechanical
properties
One of restorative
resins in dentistry could
be used by mechanical
enhancement
[53]
45 nm MPS-modified silica and
bis-GMA/TEGDMA polymer
A filler to enhance
mechanical
properties
Improved dispersion in
resins as well as
mechanical properties
[54]
Nanosheet-shaped
montmorillonite and PMMA
polymer
A filler to enhance
thermal stability
and mechanical
strength
This could be used as a
denture base material
due to good
biocompatibility
[55]
Crystalline fibrillar silicate (FS,
100
A filler to enhance
mechanical
properties
Flexural strength, elastic
modulus, and work of
fracture of 1% and
2.5% of composites
are reinforced
