ABSTRACT
AIM: This study was carried out to estimate the concentrations three microelements in enamel of deciduous normal and carious teeth using atomic emission spectrometry. METHODS: A total of 80 deciduous molar teeth indicated for extraction from children between the age group of 713 yrs. were taken for this study. The specimens were divided into four groups and the samples were prepared using centrifuge flotation technique. They were analyzed for Manganese, Strontium and Zinc using inductively coupled plasma atomic emission spectroscopy. RESULTS: This study shows that sound enamel contains more of strontium when compared to the carious enamel. Carious enamel contains more of manganese, and zinc when compared to the normal enamel. Elements zinc and strontium occur in high concentrations, where as elements manganese occur in low concentrations in enamel. The concentrations of elements manganese, strontium and zinc does not vary in relation to sex of individual. CONCLUSION: The microelements strontium and zinc are present in high concentration. Further studies are necessary to see their potential in mineralization and anticariogenic process.
