Effect of Chicken Egg Shell Powder and Gallic Acid as Remineralising Agent on Early Enamel Carious LesionAn In Vitro Study
Keywords:Caries, Demineralisation, Remineralisation, Calcium
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.
