Abstract

Background and aim: In recent years, using DENTAL AMALGAM because of its potential risk of MERCURY TOXICITY particularly for dental personnel has become a great problem in DENTISTry. The aim of this study was to evaluate the relationship between practical indices and mercury levels in the urine of DENTISTs with more than four years experience.Materials and Methods: Thirty DENTISTs filled a questionnaire including: duration of office experience, number of amalgam restorations, method of amalgam wastes removal, number of daily polished restorations, and the number of amalgam restored teeth in DENTIST"s mouth. Thirty urine samples were collected from DENTISTs and specific gravity of each urine sample was measured by a refractometer on the same day.After processing, mercury was collected from the upper layer of solution using potassium bromid and was measured by a spectro photometer (µHg/l) in 485nm. Then cratinin of each sample was also measured and mercury concentration was divided into cratinin concentration. Finally, the rate of urine mercury was reported in µgHg/gr cr. Data was analyzed by t-test, pearson correlation coeficient and lined multi variable regression test.Results: Mean value of urine mercury was 31.62, μghg/gr cr which was less than threshold allowable level.Totally, 11 samples exceed the allowable levels. From practical contaminated instruments, method of amalgam wastes removal significantly related to urine mercury levels (P<0.05).Conclusion: According to this study, the measured mercury level was less than TLV level. The most significant factor was the number of restorations.
