A comparative clinical trial to evaluate the effect of mouthwash containing "BIO Sp. White" system

Professional cleaning and polishing of teeth or the use of whitening products for oral hygiene can help remove many types of surface stains, primarily under the influence of abrasive/polishing agents. For deeper color changes, peroxide bleaching techniques are used. These methods are based on the use of hydrogen peroxide applied directly to the tooth surface, or produced by a chemical reaction of carbamide peroxide or sodium perborate [1]. In spite of peroxide efficacy, adverse effects have become evident. Cervical root resorption and tooth sensitivity are possible consequence of internal bleaching and are more frequently observed in teeth treated with the thermo-catalytic procedure [2]. In fact, tooth sensitivity is experienced in 15-78% of patients undergoing tooth bleaching [3].
