The purpose of the present study was to determine the mercury in human scalp hair and urine from amalgam fillings, sixty-five subjects were examined their oral status, alginate impression were taken to make dental arch stone models and calculated their surface area of amalgam fillings. The 28 control subjects had no amalgam filling and 37 compare subjects had an average of 12 surfaces of amalgam. The morning urine and scalp hair were collected from all subjects and samples were digested in acid digestion bomb(Parr Instrument Company, U.S.A.) The mercury contents were determined with atomic absorption spectrophotometer(Model 551, IL Co., U.S.A.) and atomic vapor accessory (Model 440, IL Co., U.S.A.) . The results obtained were as follows ; 1. The urinary mercury contents of control group(no amalgam in oral cavity) were 2±10.0㎍/g. creatinine/L and compare group(amalgam filling) were 16.7±16.0㎍/g. creatinine/L(p<0.05). 2. The scalp hair mercury contents of amalgam filling group(3.29±1.03㎎/L) were slightly higher than those of the amalgam free group(3.04±1.11㎎/L) but not significant difference(p>0.05). 3. The linear correlation coefficient was 0.3490 and significantly different between mercury content of scalp hair and amalgam surface area(p<0.05), but had no significant difference between urinary mercury contents and amalgam surface area(r=0.0934, p>0.05).
