Evaluation of urinary mercury levels in dentists of Dentistry department of Ahvaz oil industry`s health care, in 2010
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 11
Abstract
Background: Occupational exposure to dental amalgam, could exposes them to Inhalation of mercury vapor; If Mercury accumulation exceeds the allowed limit(overloads) in the body, their health would be at risk, that it is considered as a problem. Measuring urinary mercury is a sensitive and reliable method for determining the amount of exposure to that. The present study was performed with the objective of measurement urinary mercury in dentists of Dentistry department of Ahvaz oil industry`s health care,with work experience more than two years, in 2010.In this descriptive-analytical and cross - sectional study, 37 dentists with work experience at work more than two years, were studied. Urine samples were collected in the considered day and a questionnaire containing questions about individual characteristics , such as age, work experience, number of teeth restored with Amalgam in the mouth, was completed. Urine samples were Analyzed using Atomic Absorption Spectrophotometry. In order to analyze the data, Corel indicators and Distribution were used, Descriptive statistics was used for data description, Kolmogorov-Smirnov test to investigate the distribution of the data and Spearman and Pearson correlation coefficients also were used to evaluate the amount of relationship (linear) between the variables.Also T-Test Analysis used in order to compare urine mercury levels between men and women ;and Analysis of variance used for comparison between various levels and groups. Analysis of variance was utilized with Tukek Post Hoc test and a Significance level of 0.05 was concidered,for all statistical analysis procedures.The mean urinary mercury in dentists was 3.4 ±2.2 micrograms per liter. No statistically significant correlation between urine mercury levels with variables such as : age, work experience, number of teeth restored with Amalgam, was observed.Based on the findings of this study, the mean urinary mercury Dentists, in dentists of Dentistry department of Ahvaz oil industry`s health care, was lower than the Allowed job threshold(35 micrograms per liter). Among the studied variables (age, work experience, number of teeth restored with Amalgam) ,none had significant with urinary mercury levels .
