| dc.description.abstract | The use of soft denture liner (SDL) for long periods can increase plaque
accumulation and make the oral cavity environment more anaerobic. An anaerobic
environment can promote the excessive growth of microorganisms, especially
Candida albicans, which can increase the risk of denture stomatitis. Therefore, SDL
must be cleaned regularly. The most common cleaning method is chemical cleaning
through immersion in a cleaning solution. However, immersion in cleaning solutions
can cause changes in the material properties due to water absorption by the fillers in
the SDL material, potentially leading to color changes. Therefore, the cleaning
material selected must have good antimicrobial effectiveness without significantly
affecting the SDL's properties, including its chemical and physical properties, such as
water absorption and color stability. Regular use of cleaning materials is
recommended to clean SDL of microorganisms, plaque, and food debris. One
cleaning agent that can be used is sodium hypochlorite. The purpose of this study is
to determine the effect of immersion of autopolymerizing silicone-based soft denture
liners in sodium hypochlorite on water absorption and color stability. This research is
a laboratory experimental study. The study was conducted on samples of
autopolymerizing silicone-based SDL immersed in 0.5% sodium hypochlorite and
distilled water (control), with 24 samples of size 15×2 mm. Each sample was tested
using an analytical balance to determine the water absorption rate and a colorimeter
to measure color stability. Data was analyzed using univariate tests to determine the
mean and standard deviation, and an independent T-test to assess the effects of immersion and the difference in immersion duration (2.5 and 5 days) on water
absorption and color stability. The results of this study showed that the mean and
standard deviation of water absorption in SDL immersed in 0.5% sodium
hypochlorite for 2.5 days were 0.36±0.05, and in distilled water were 0.27±0.05. The
mean and standard deviation of water absorption in SDL immersed in 0.5% sodium
hypochlorite for 5 days were 0.71±0.08, and in distilled water were 0.46±0.06. The
mean and standard deviation of color stability in SDL immersed in 0.5% sodium
hypochlorite for 2.5 days were 0.91 ± 0.15, and in distilledwater were 0.37 ± 0.08. The
mean and standard deviation of color stability in SDL immersed in 0.5% sodium
hypochlorite for 5 days were 1.46 ± 0.21, and in distilledwater were 0.54± 0.10. Based
on the independent T-test results, it was found that immersion of silicone-based
autopolymerizing SDL in 0.5% sodium hypochlorite had an effect on water
absorption and color stability. The independent T-test also showed a difference in the
effect of immersion duration on water absorption and color stability. This study
concluded that 0.5% sodium hypochlorite can be used as a cleaning agent. | en_US |
