Hair mineral analysis in the assessment of exposure to metals of orthodontic patients
Contents of 6 heavy metals and Si were detd. by inductively coupled plasma optical emission spectrometry in hair samples collected in a group of 25 students chronically exposed (today or in the past) to metals contained in fixed or removable orthodontic appliances. Increased contents of all metals (as compared to the control of 58 people) were obsd. but only for Cr the difference was statistically significant.
