摘要:
"tooth whitening composition, method and system for whitening and desensitizing a person's teeth". compositions and methods including a dental bleaching agent and potassium nitrate for increased whitening and reduced tooth sensitivity. Potassium nitrate both increases tooth whiteness in addition to the whitening effect of the dental agent and reduces or eliminates tooth sensitivity that would otherwise be caused by the bleaching agent. For prolonged treatment of teeth, lower amounts of potassium nitrate (eg 0.5%) were actually considered to have better results than larger amounts (eg 3%). The dental compositions (40) may be applied directly to the person's teeth, or they may be carried on a thin-walled, flexible, comfortable-fitting dental tray (50) and applied to the person's teeth. In this case, the dental compositions (40) will include a tackifier such as carboxypolymethylene which assists the composition in retaining the dental tray (50) on the person's teeth as a result of the adhesive properties of the dental composition (40). preferably that due to the mechanical interlocking of the tray 50 over the teeth of the person. Dental compositions may additionally include anti-cariogenic and antimicrobial agents."composição de alvejamento dental, método e sistema para o branqueamento e dessensibilização dos dentes de uma pessoa". composições e métodos, que incluem um agente de alvejamento dental e nitrato de potássio para aumento do branqueamento e redução da sensibilidade dental. o nitrato de potássio tanto aumenta a brancura dos dentes além do efeito de branqueamento do agente dental, como reduz ou elimina a sensibilidade do dente, que seria de outro modo causada pelo agente de alvejamento. para o tratamento prolongado dos dentes, quantidades mais baixas de nitrato de potássio (por exemplo, 0,5%) foram efetivamente consideradas como tendo melhores resultados do que quantidades maiores (por exemplo, 3%). as composições dentais (40) podem ser aplicadas diretamente ao
