摘要: Objective The aim of this pilot clinical study was to determine the mercury release from amalgam fillings and antioxidant enzyme activities (Superoxide Dismutase [SOD] Catalase[CAT] ) in body fluids after exposure two different vital tooth bleaching systems. Material Methods Twenty eight subjects with an average age 25.6 years (18–41) having at least but not more than four Class II on each quadrant arch mouth participated study. Baseline concentrations levels whole blood, urine, saliva were measured by a Vapor Generation Accessory connected Atomic Absorption Spectrometer. Erythrocyte enzymes, SOD, CAT blood determined kinetically. Subjects randomly assigned groups 14 volunteers. Group 1 treated at-home system (Opalescence PF 35% Carbamide Peroxide, Ultradent), 2 chemically activated office Xtra Boost 38% Hydrogen Ultradent) according manufacturer's recommendations. Twenty-four hours treatments, enzymes remeasured. Results There no significant differences before treatments (p > 0.05). No also found level (SOD CAT) Mercury did affect (p > 0.05). Conclusion Bleaching either or home amount released antioxidant-enzyme blood. Clinical Significance Bleaching systems tested have deleterious effect fluids.
