Abstract:
Objective: To evaluate the remineralizing effe ct of glass ionomer cement (GIC),calcium hydroxide(Dycal)and zinc phosphate ceme nt on soft dentin. Methods:Standard cavity of 1 mm?2 mm was pre pared on each of the 60 premolars extracted for orthodontic treatment. The teeth were randomly divided into three groups with 20 in each after demineralization ,the cavities were blocked by GIC, Dycal and zinc phosphate cement respectively and filled with zinc oxide. All the teeth were dipped in man-made saliva for 3 0 days.Then the samples were sectioned, microradiographied and the mineral conte nt were determined by microdensitometry. Results:The remineraliz ing rate in the group of GIC, Dycal and zinc phosphate cement was 31.22%,13.19 % and 8.92% respectively (P
