Summary: | Background: Surface roughness is an important property of
denture bases since denture bases are in contact with oral
tissues and a rough surface may affect tissues health due to
microorganism accumulation. Therefore, the effect of cigarette
smoke on the surface roughness of two commercially available
denture base materials was evaluated to emphasize which type
has superior properties for clinical use.
Materials and Methods: A total numbers of 40 specimens
were constructed from two commercially available denture
base materials; heat-cured PMMA and visible light cured UDMA
resins (20 for each). The specimens for each type were randomly
divided into: Group I: Heat cured resin control group; Group
II: Heat cured acrylic resin specimens exposed to cigarette
smoking; Group III: Light cured resin control group; Group IV:
Light cured resin specimens exposed to cigarette smoking.
The control groups used for immersion in distilled water and
the smoke test groups used for exposure to cigarette smoking.
The smoke test groups specimens were exposed to smoking
in a custom made smoking chamber by using 20 cigarettes for
each specimen. The surface roughness was measured by using
Pocket SurfPS1 profilometer and the measurements considered
as the difference between the initial and final roughness
measured before and after smoking.
Results: The t-test for paired observation of test specimens
after exposure to smoking was indicated significant change in
surface roughness for Group II (p< 0.05) but has no significance
with Group IV. Otherwise, there were no significant differences
with control groups (Group I and III).
Conclusion: The surface roughness of the dentures constructed
from heat cured acrylic resin had been increased after exposure
to cigarette smoke but had no impact on the dentures
constructed from visible light cured resin. |
