This paper aims to investigate if the dental restoration of nickel-chromium based alloy (Ni-Cr) leads to the enhanced excretions of Ni and Cr in urine. Seven hundred and ninety-five patients in a dental hospital had single or multiple Ni-Cr alloy restoration recently and 198 controls were recruited to collect information on dental restoration by questionnaire and clinical examination. Urinary concentrations of Ni and Cr from each subject were measure by graphite furnace atomic absorption spectrometry.

Methods: Seven hundred and ninety-five Ni-Cr alloy consumers were investigated by the questionnaire and the biological examination of renal function. The correlations between renal function parameters and urinary Ni(or Cr) were determined by Student's t test, one-way ANOVA, and Logistic regression analysis using SPSS12.

Objective: To investigate the immunological function parameters in patients undergoing dental restoration of nickel-chromium (Ni-Cr).
Methods: Seven hundred and ninety-five Ni-Cr alloy consumers as exposure group, together with 198 controls, were surveyed by the questionnaire and the biological examination of immunological function.
Results: After splitting all subjects into three groups of equal sample size by urinary Ni or urinary Cr, serum interleukin-1beta(IL-1β) was found to be significantly higher in the group of urinary Ni > 115.
