Abstract
Background: The reduction in the tooth surface micro-hardness denotes enamel surface destruction due to loss of the mineral content after exposing to demineralization process or carious lesion, which could be reversed by creating a suitable remineralization environment via using different remineralizing agents. Aim of the study: Study the efficacy of remineralizing agents (varnishes) with different techniques: Bioactive Glass (BAG), Recaldent technology: Casein Phosphopeptide Amorphous Calcium Phosphate (CPP-ACP), Silver Diamine Fluoride (SDF), and Sodium Fluoride 5% (NaF) on the enamel surface micro-hardness of the maxillary deciduous canine teeth. Materials and Methods: Fifty sound deciduous maxillary canine teeth were used as the experimental samples, and randomly distributed into 5 groups with 10 teeth for each group. The groups were: Group 1 (SDF), Group 2 (BAG), Group 3 (CPP-ACP), Group 4 (NaF), Group 5 Control kept in prepared artificial saliva without any treatment. All teeth samples of the whole groups were kept for 72 hours in specifically prepared demineralizing agent to produce artificial enamel carious lesion, then treated with remineralizing agent and measured after 2 weeks. Results: The results revealed that there was a significant decrease in the surface micro-hardness for the whole samples after demineralization. Comparing to the control (Group 5), there was a significant increase in the surface micro-hardness in the groups 1, 2, 3. Conclusion: According to the outcomes of the current study, groups (BAG, CPP-ACP, and SDF) were significantly higher in effect when compared with artificial saliva, except NaF group that showed better effect but not significant difference.
