Abstract
Object: The purpose of this study was to examine fluoride concentration of spot urine and fingernails of preschool children in a fluoridated and non-fluoridated community and to assess the association between the two fluoride conc ntrations.
Method: Eighty five children (45 boys, 40 girls) in preschool participated in this study. For this study, we compared forty five children in a fluoridated community to forty children in a non-fluoridated community. While fluoride concentration of spot urine was directly analyzed by a fluoride ion specific electrode, on fingernails was analyzed on the same matching after pre-processing by hexamethyldisiloxane (HMDS) diffusion method. Data were analyzed by Student’s t-test and Pearson correlation analysis.
Result: The fluoride concentration of spot urine was 1.06±0.49 ㎍/g in a fluoridated community and 0.51±0.41 ㎍/g in the non-fluoridated community (p <.001). The fluoride concentration of fingernails was 6.43±3.98 ㎍/g in a fluoridated community and 4.06±2.74 ㎍/g in non-fluoridated community (p<.001). The correlation coefficeint between the 2 fluoride concentrations was 0.257 (p <.05).
Conclusion: We found the possibility of a fluoride concentration monitoring system by using spot urine and the fingernails of preschool children in fluoridated community.
