| Summary: | Thermoplastic nylon used as denture base material shows unwanted
elasticity modulus alteration after half year wear. Elasticity modulus alteration on
thermoplastic nylon influences on elasticity which is noted as one of thermoplastic
nylon advantage. This study was aimed to determine the effect of alcohol
concentration and immersing duration on elasticity modulus of thermoplastic
nylon as denture base material.
Eighty thermoplastic nylon plates in 2.4 x 10 x 6.4 mm dimension were
used in this study. Sample was divided into 8 groups of ten to each. All samples
were immersed in sterile distilled water for 48 hrs at 37oC then in alcoholcontaining
mouthwash solution. Thermoplastic nylon plates group 1 and 4 were
immersed in 7% alcohol-containing mouthwash solution, group 2 and 5 in 17%
alcohol-containing mouthwash solution, and group 3 and 6 in 27% alcoholcontaining
mouthwash solution for 30 min once a day. In group 7 and 8,
thermoplastic nylon plates were immersed in 37oC sterile distilled water as
control. Elasticity modulus was measured after 7 and 14 days immersion using
Universal Testing Machine. Data obtained were analyzed using two ways anova
and Least Significant Difference (LSD) methods.
This study results showed: 1) elasticity modulus of thermoplastic nylon as
denture base material among alcohol concentration were significantly different
