Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Oral and Dental Medicine - Department of Operative Dentistry Summary: Aim of study: evaluate the effect of bioactive glass and casein phosphopeptide- amorphous calcium phosphate(CPP-ACP) on repairing the color of enamel white spot lesions after 1, 30 and 60 days. Material and method:Thirty non carious extracted human premolar were selected in this study. Teeth were randomly divided into four main groups by coloring the surface of each tooth root with a different varnish color. G1: control positive, G2: control negative, G3: bioactive glass, G4: CCP-ACP. All the teeth were immersed in demineralizing solution for 72 hours. Then each group were further subdivided into three subgroups according to the aging time; (T₁: 1 day, T₂: 3o days, T₃: 60 days). All samples were tested by spectrophotometer to measure thecolor differences ({u2206}E) when compared to sound and demineralized enamel. The results were calculated and statistically analyzed using One way ANOVA followed by pair-wise Tukey{u2019}s post-hoc tests. Results:both bioactive glass and CPP-ACP statistically significant to improve the color of demineralized enamel after one and 30 days. After 60 days bioactive glass showed the lowest statistical significant mean {u2206}E.The effect of the time storage was statistically non-significantly for both bioactive glass and CPP-ACP, while it was significant for the negative control group. While it showed at 60 days the lowest statistical significant mean {u2206}E. Conclusion:Bioactive glass and CCP-ACP are goodremineralizing agents that cause repair the color of demineralized enamel, Time didn't decrease the effect of bioactive glass while its negatively affecting the color repair capacity of CCP-ACP
