Thesis (M.Sc.)--Chulalongkorn University, 2015

This study aimed to evaluate the effect of an acidic-adjusted pH of solvent and drying temperature in silanization on the amount of fluoride released and mechanical properties of heat-cured acrylic resin containing a silanized fluoride-releasing filler. The experimental groups (pH effect) were divided into 4 groups; non-silanized, acidic-adjusted pH, non-adjusted pH, and no filler as control. The experimental groups (temperature effect) were also divided into 4 groups; T25, T50, T110, and no filler as control. For fluoride measurement, each specimen was placed in deionized water which was changed every day for 7 days, every week for 7 weeks and measured. The flexural strength and flexural modulus were evaluated after aging for 48 hours, 1, and 2 months. For pH effect, two-way ANOVA indicated significant differences among groups, storage times, and its interaction in fluoride measurement and flexural modulus. For flexural strength, there was significant difference only among groups. Acidic-adjusted pH of solvent in silanization enhanced the amount of fluoride released from acrylic resin, while non-adjusted pH of solvent exhibited better flexural strength of acrylic resin. For temperature effect, two-way ANOVA indicated significant differences among groups, storage times, and its interaction in fluoride measurement and flexural modulus. For flexural strength, there was significant difference on two main factors. The flexural strength of all groups at 2 months were comparable to 48 hours storage time. T50 was suggested for silanization of fluoride releasing filler before mixing with heat-cured acrylic resin as it increased the amount of fluoride released.
