| Summary: | Background: The discolouration of artificial teeth, which
hampers aesthetics, is one of the negative effects of cigarette
smoking. Therefore, the effect of cigarette smoke on the colour
stability of commercially available acrylic resin teeth needs to be
evaluated for clinical success and to ascertain as to which brand
has superior properties.
Materials and Methods: Three commercially available acrylic
teeth were evaluated, after division into Group A (Premadent),
Group B (Astra), and Group C (Sanyo- Dent). Selected brands
were subdivided as study group and control group. Each set of
acrylic resin teeth were stored in artificial saliva at 37±1oC for 24
hours. After 24 hours of immersion, the colour measurement of
each tooth (T0) was performed. Second colour measurements
were done after 21 days (T21) of exposure to cigarette smoke
for study group and after immersion in artificial saliva for control
group. All data was statistically analyzed by using Repeated
Measures ANOVA and Two-way ANOVA.(p<0.05)
Results: Group A showed least total colour change on exposure
to cigarette smoke, followed by Group B and Group C had the
highest total colour change. In control group, after immersion
in artificial saliva, a slight increase in total colour change was
observed for all groups, which was clinically acceptable.
Conclusion: Group A (crosslinked acrylic resin teeth) was more
colour stable and more resistant to the discolouration which was
caused by cigarette smoke, followed by Group B (crosslinked
acrylic resin teeth). Group C (Non-crosslinked acrylic resin teeth)
was least colour stable and most susceptible to discolouration
which was caused by cigarette smoke. |
