Abstract

Thermoplastic nylon can be used as a denture base. Thermoplastic nylon has the ability to absorb the solution thus causing linear expansion. Lime extract (Citrus aurantifolia) is the cleanser for thermoplastic nylon denture. The aim of this study was to know the effect of durations immersed thermoplastic nylon in 40% lime extract on dimensional changes. This study used 32 thermoplastic nylon specimens (Bioplastic, size 65 mm x 10 mm x 2.5 mm) 16 specimens were immersed in lime extract and 16 specimens in distilled water (control). Immersion is performed for 1 year (61 hours) and 2 years (122 hours). The study was an experimental laboratories using a travelling microscope to measure dimensional changes of the specimens. Data were analyzed by one way ANOVA. The result showed there was significant difference of dimensional changes after immersion in 40% lime extract for 1 year and 2 years (p0.05). LSD test showed there was significant difference of dimensional changes of thermoplastic nylon after immersion for 2 years (p0.05) than immersion for 1 year. The conclusion of this study shows that there was effect of durations immersed thermoplastic nylon in 40% lime extract on dimensional changes.
