Abstract :
Composite resin is a filling or restoration
material that has a similar color to the teeth, is
insensitive to dehydration, and is relatively easy to
manipulate. One of the nanotechnology developments in
dentistry is nano fill and nanohybrid composite resin
with minute particle sizes, which has a different value in
its physical, mechanical, and optical properties. In the
oral cavity, composite resin restoration material comes
in contact with various salivary pH, acidic or alkali that
can affect physical property changes, including surface
roughness. Chitosan is a biomaterial continuously being
developed because it has many medical benefits and has
proven safe to use on people. This study analyzes
composite resin restoration strength when nanoparticle
chitosan high molecular is added 1% to its surface
degradation. Samples are 36 human premolar teeth
randomly classified into 12 groups (r=3). Each group is
classified based on different filling materials and
salivary pH. Scanning Electron Microscopy (SEM)
samples are tested to see the surface degradation. The
result of this study shows that using composite resin,
either nanofiller or nanohybrid, will go through salivary
degradation on pH 3, 5, 7, dan 10. The lower the pH, the
higher the degradation, Adding 0,1% chitosan on nano
fill and nano hybrid shows that there is still degradation
in the restoration surface. 0,1% Chitosan added in nano
hybrid composite resin on pH 7 offers surface stability,
although degradation is still found. The 0,1% chitosan
added into nano fill composite resin shows a different
value although still lower than nano hybrid composite
added with 0,1% chitosan on surface degradation.
Adding 0,1% high molecular Chitosan to both
nanocomposite resins shows a better value when
compared to the composite resin that is not infused with
Chitosan.
