30 I I industry report _ Opalescence Treswhite Ortho _The following article describes the use of a new dental whitening product based on hydro- gen peroxide (H2O2). The effect of this compound whitens dentine in multidirectional angles, reach- ing areas covered by brackets, making it possible to achieve teeth whitening under braces. Patients are very willing to use this whitening procedure, both in-office and at home, because they want to achieve white teeth while under orthodontic treatment. The result is a whitening technique that also achieves a marked increase in patients’ oral hygiene habits. The use of the H2O2 as a dental whitening agent was first described by Kingsbury in 1861. The den- tists’ desire to provide fast and effective teeth whitening procedures was described by Abbot in 1918, when he introduced a wonderful and re- volutionaryin-officedentalwhiteningtechnique— a 35 % H2O2 concentration together with heat emission from a lamp to increase oxidation.1 In 1989, Haywood and Heymann described a tech- nique for daily use that used a low carbamide per- oxide concentration to remove deeper teeth stains, which increase with age.2 _Dental whitening popularity The success of H2O2-based teeth whitening products has been accepted and validated by research. The successful use of H2O2 for dental whitening, using different techniques for in-office and at home treatment, has been described by many authors.3 Messages on TV and in newspa- pers, magazines and other media have popularised dental pigments and teeth-stain removal, caused by age, food, cigarettes, tea, and beverages with colorants, amongst others causes. People ask for dental whitening treatments to achieve better aesthetics, improve their smile and their self- esteem, all of which are closely related to dental pigmentation.4 cosmeticdentistry 3_2010 First whitener for fixed-bracesorthodontics Authors_ Dr Enrique Jadad, Dr Jaime Montoya & Prof Gonzalo Arana, Colombia Fig. 1_Patient under orthodontic treatment.
