The Effect of Denture Cleanser Materials on Impact Strength of Heat Cure Acrylic Resin

Abstract

Acrylic denture base is the part of the denture that rests on the foundation tissue &
to which the teeth are attached. The main objective of this study was to determine the
effect of different cleansers solution on the impact strength of heat cure acrylic resin.
Thirty (30) rectangular shape samples from acrylic were prepared with dimension of
(55 mm *10 mm *2.5 mm) length, width& thickness .The acrylic was fabricated in
the same conventional way for construction base palate. All the specimens were
examined by vernier before immersion in solution to check the size of each samples,
the samples were divided into three group (A, B& C) each group contain ten samples.
The samples in first group (A) were immersed in distilled water, the samples in
second group (B) were immersed in peroxide solution, while the sample in the third
group (C) were immersed in prepared cleanser solution (citric acid).After period of
immersion (for 3 week & 15 minutes every day).Finally each samples rinsed by
distilled water & cleaned thoroughly by apiece of cotton before testing. The impact
strength was tested in chapy impact machine. The statistical analysis of the results
showed that there was no statically significant difference in impact strength value
among the testing groups. This means that the all cleanser solution that were used in
this study had no effect on the impact strength
