summary The study aimed at determining hydrogen peroxide recovery in saliva during use of different home bleaching products by smokers and non‐smokers. Peroxide recovery was evaluated with respect to the safe level reported in the literature. Determination of peroxide levels in saliva was performed with peroxidase, phenol and 4‐aminoantipyrin in a photometric method. Four different bleaching regimens were used by 10 smokers and 10 non‐smokers: Whitestrips, Vivastyle (tray‐based) and two paint‐on products (Crest Night Effects, Colgate Simply White). Whole saliva was collected and total amount of peroxide (mg) released during the 60 min bleaching period was determined: Colgate Simply White: 2·67 ±0·88 (non‐smokers); 2·66 ± 1·17 (smokers); Crest Night Effects: 0·23 ± 0·13 (non‐smokers); 0·25 ±0·16 (smokers); Vivastyle: 2·47 ± 0·82 (non‐smokers), 2·44 ± 1·31 (smokers); Whitestrips: 1·39 ± 0·62 (non‐smokers), 2·02 ± 1·86 (smokers). In terms of amount of peroxide kg −1 body weight the bleaching systems led to a single exposure of 0·004–0·046 mg kg −1 , which is distinctly less than safe daily dose of 0·26 mg kg −1 day −1 , if calculated for a small person (58 kg). The criterion smoker versus non‐smokers had no influence on peroxide levels in the oral cavity. Conclusion : Smoking did not appear to impact the anti‐oxidant defence capacity of the oral cavity with respect to degrading peroxides released from bleaching products. Significantly lower amounts of peroxides were detected in saliva during application of the paint‐on product Crest Nights Effects compared with the other bleaching systems.
