In-vitro evaluation of remineralization efficiency of chicken eggshell slurry on eroded deciduous enamel

OBJECTIVES: The present study evaluated the re-mineralizing efficiency of CESP on experimentally eroded deciduous tooth enamel by Claritin syrup.
MATERIALS AND METHODS: 20 extracted deciduous teeth had been selected and stored in normal saline. Each tooth was cut in a labiolingual direction into 2 halves, one half used as a control and the other used as study. Demineralization of all specimens were done by twice daily immersion in Claritin syrup for ½ an hour for 12 days to form enamel erosion. Remineralization of the study group was done by using CESP slurry twice daily application for 3min. for 10 days. Surface roughness of the specimens was measured by surface profile gauge and microhardness evaluation was done using Vickers tester. Resulted data were tabulated and ana1yzed statistically by t-test with 5% significance 1evel
RESULTS: There was statistically significant increase in roughness values after erosion with Claritin syrup (P<0.001). however, it was significantly decreased after remineralization (P=0.01). There was statistically significant decreased mean value of microhardness after erosion with Claritin syrup (P<0.001). however, it was significantly increased after remineralization (P=0.01).
CONCLUSION: CESP slurry is a valuable topical treatment in deciduous teeth erosion since it decreased the roughness and increased the microhardness of the enamel surface in-vitro
