Abstract
Aims: The aims of this investigation were to determine the effect of incorporation of CaCO3 from egg shell and Fluoride salt NaF in different concentrations on transverse strength of RESPAL® NF(VEIN 24) heat cured acrylic resin denture base. Materials and Methods: 21 samples of heat cured acrylic resin were prepared, divided it’s into 7 groups; the 1st group Control HCAR , the 2nd group HCAR mixed with 2.5% CaCO3, the 3rd group HCAR mixed with 5% CaCO3, the 4th group HCAR mixed with 10% CaCO3 and the 5th group HCAR mixed with 2.5% NaF, the 6th group HCAR mixed with 5% NaF, the 7th group HCAR mixed with 10% NaF . The samples were tested after 48 hours from preparation for transverse strength test. Results: One way ANOVA and Duncan Multiple Analysis rang test were used and showed significant differences in the transverse strength between the two groups (CaCo3 and NaF), and significant differences between control and CaCo3 while no significance between control and NaF groups. Conclusions: It was concluded that adding NaF to HCAR led to an increase in strength of denture base and significant decrease in strength when adding CaCO3 to HCAR .This was within acceptable range of American Dental Association specification no.12 ,1975.
