Objectives: The aim of this study was assessment of the variation of urinary mercury concentrations after removal of amalgam fillings in children.
Methods: 10 elemental school children with amalgam filling tooth surfaces were took part in this study. One dentist recorded the number of amalgam filling surface, and general characteristics of subjects were surveyed by questionnaire. Each urine samples were collected before, immediately after and after 24 hours amalgam removal. The statistical analysis was performed using the SPSS 18.0.
Results: The mean concentration urinary mercury immediately after amalgam removal was higher (5.70±1.20 ㎍/g creatinine) than before amalgam removal (5.28±1.53 ㎍/g creatinine). The mean concentration urinary mercury level whose have 1-10 amalgam removal surfaces was increased after amalgam removal compared with before.
Conclusions: Mercury concentration in urine was influenced by amalgam removal.
