Abstract

Twenty freshly extracted non-carious human molars were used. The mineral content of all teeth was initially assessed using EDX. Teeth were then divided randomly into two groups each containing ten samples. All teeth were placed in demineralizing agent after which one group (I) was remineralized using egg shell solution while the other group (II) was remineralized using fluoride varnish (Proshield, President dental Germany). This process was held in a pH cycling mode.Regarding mineral content specimens of both groups were initially assessed (base line measurements), then reassessed directly after demineralization, three days from remineralization and at the end of seven days remineralization period. Results were as follow : Regarding Ca wt % and comparing the two groups there was no statistical significance at base line measurements, after demineralization and after three days from remineralization. Meanwhile after seven days remineralization group (I) demonstrated statistically significant lower mean Ca atomic wt % than group (II). Regarding phosphorus atomic wt % for measurements of base line, after demineralization and after remineralization there was no statistical significance between the two groups. Regarding the effect of time for Ca wt % and after seven days group (I) showed non statistically significant decrease in Ca wt % compared to that at base line, while group (II) showed non statistically significant difference from the value measured at base line. For the P wt % and after seven days both groups demonstrated non statistically significant lower mean values compared to base line data.
