Monitoring the oxidative stress in hairdressers' in exposure to the vapors from the dyes of the hair, by analysis of salivary malondialdialdeyde with the use of Dipsticks
OBJECTIVES: The objective of this study is determinate with a semi quantitative method (dipsticks), the oxidative stress, produced by exposure to dyes of hairdressers, measuring the concentration of salivary malondialdehyde (MDA). MATERIALS AND METHODS: Saliva samples are provided by the hairdressers and a control group. The values of MDA are determinate using dipsticks, in a range ≤ 3 and ≥ 7 nM / ml, and For 14 random samples of saliva, the MDA, was also determined spectrophotometrically.
