Effect of Chicken Egg Shell Powder and Gallic Acid as Remineralising Agent on Early Enamel Carious Lesion- An In Vitro Study.

Background: The aim of the study was to compare the effect of chicken eggshell powder and gallic acid as remineralising agent on early enamel caries lesion. Material and Methods: Ten extracted deciduous molars was cleaned using distilled water. The teeth were decoronated at CEJ. Each decoronated tooth then sectioned longitudinally in a mesio-distal direction first and then in a bucco-lingual direction with diamond disc so that four samples obtained from a single tooth. Then from these samples, four enamel blocks of dimensions (4mm long, 4mm width and 2mm thick) made from each sample and embedded in acrylic blocks. These 40 samples are divided into four groups, each having 10 samples (GROUP A,B,C,D). Samples were demineralised followed by application of chicken egg shell solution and gallic acid. Chicken egg shell has the highest content of Calcium present as compared to Gallic acid.The ratio of Calcium/Phosphorous was found to be increased in the following sequence. Chicken egg shell>Gallic acid>Control>Demineralised group. Conclusion: It can be concluded from the results shows that Calcium has a vital role in remineralisation. [ABSTRACT FROM AUTHOR]
