| Abstract | ||||
| Purpose: This study was performed to examine the effect of cranberry extract and nano-hydroxyapatite powder mixed with olive in different times of application on microhardness and micromorphology of white spot lesion. Materials and Methods: A total 16 premolars were selected. The samples were sectioned mesiodistaly into two halves to obtain 32 specimens, then divided into two groups according to materials used; A1: Cranberry extract, A2: Nano-hydroxyapatite paste. The two groups were subdivided into two subgroups according to the time of assessment; B1: after 10 minutes and B2: after 8 days of material application. All the samples were treated by demineralizing solution for 72 hours, and then the tested materials were applied. Microhardness test was performed three times for each sample, at baseline, after demineralization and after treatment for each period of time (after 10 minutes and after 8 days). SEM was performed to detect the change of micromorphology of the specimens. Results: Microhardness results revealed that both the two materials show significant increase in microhardness with no significant difference between them. SEM demonstrated improvement in demineralized enamel surface defects in the two test groups. Conclusion: Cranberry extract and nano-hydroxyapatite powder mixed with olive oil could be considered as effective options to re-mineralize the white spot lesion of enamel regardless of the time of application. | ||||
