Effect of green tea on enamel remineralization of teeth immersed in Pepsi

Introduction: A rise in acidic products consumption has led to an increase in the percentage of eroded enamel and dentin. A new remineralization method is the consumption of green tea, which suspected to have remineralization properties.
Aim of the work: This study determined the impact of green tea on enamel remineralization of immersed teeth in pepsi.
Materials and Methods: After clinical and radiographic examinations, 30 sound permanent posterior teeth that were newly extracted for orthodontic purposes were chosen. Each tooth was sectioned into 4 quadrants at right angle to the root long axis. We choose cervical region for the present research. Sectioned teeth were grouped into 3 sets; 40 specimens for each. Group I: served in artificial saliva. Group II: specimens immersed in Pepsi beverages. Group III: specimens were demineralized by Pepsi drink for 3 hours and then immersed in green tea. All samples have been evaluated after 4 weeks using scanning electron microscopy
Results: The application of green tea has considerably reduced the roughness of the enamel surface, improving the capacity for enamel remineralization.
Conclusions: Green tea is effective in preventing the erosion of enamel and a promising remineralization material
