چکیده
Background: Fixed orthodontic treatment has been associated with certain side effects such as white spot lesions (WSLs). Many studies showed the positive effect of sodium fluoride (NaF) varnish in remineralizing WSLs. Studies revealed that silver diamine fluoride (SDF) is effective in arresting dentin caries, but its potential for enamel remineralization has not been investigated clearly. The present study aimed to compare the effect of SDF and NaF on the microhardness of demineralized enamel. Methods: A total of ۶۰ intact premolar teeth were collected and divided into ۴ equal groups. Group ۱ remained intact (control). Groups ۲ to ۴ were exposed to artificial cariogenic solution to create enamel lesion. Then, groups ۳ and ۴ were treated with NaF ۵% and SDF ۳۸%, respectively. After one month of storage in artificial saliva, NaF and SDF were reapplied. One month later, the surface microhardness values (SMHs) of teeth were assessed. Results: The results of ANOVA showed a significant difference among the ۴ groups (P< ۰.۰۰۱). There was significantly higher enamel microhardness in the control group compared with groups ۲ and ۳ (P< ۰.۰۰۱); however, it was not significant for the SDF group (P=۰.۱۶۰). There was significantly higher enamel surface microhardness in groups ۳ and ۴ compared with group ۲ (P≤۰.۰۰۱) and significantly higher mean SMH values in the SDF group compared with the NaF group (P=۰.۰۰۴). Conclusions: NaF varnish and SDF can both remineralize early enamel lesion but SDF has greater remineralizing potential.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
