Abstract(s)
As discromias dentárias resultantes da acção de múltiplos factores externos ou internos, são na
actualidade facilmente revertidas através de técnicas de branqueamento.
Os principais agentes utilizados em dentes vitais são o Peróxido de Hidrogénio ou de Carbamida,
com percentagens e técnicas de aplicação há muito tempo estudadas, e cuja eficácia está
cientificamente comprovada. As restrições induzidas pela Comunidade Europeia, levam as casas
comerciais a tentar impor novas técnicas isentos de peróxido de hidrogénio. Para superar a
imposição de percentagens inferiores a 6% de Peróxido de Hidrogénio, os estudos mais recentes
indicam que as fontes de luz poderá ser um benefício no resultado final do branqueamento
dentário.
No futuro novas técnicas, usando radiofrequência ou os ultrassons, poderão substituir o peróxido
de hidrogénio. No entanto, não existem estudos com validade científica que suportam a sua
utilização de forma sistemática, e actualmente, a técnica clássica apresenta a melhor relação
custo/benefício pela sua segurança/previsibilidade.
Dental dyschromias resulting from the action of multiple external or internal factors are currently and easily reversed by teeth bleaching techniques. The main whitening agents used in vital teeth are the Hydrogen or Carbamide Peroxide, with percentages and techniques of application long studied, and whose effectiveness is scientifically proven. The restrictions induced by the European Community, lead the commercial companies trying to import new techniques exempt of hydrogen peroxide. To overcome the imposition of percentages below 6% of Hydrogen Peroxide, more recent studies indicate that light sources may be of benefit in the final outcome of tooth whitening. In the future, new techniques, using radiofrequency or ultrasound, may replace hydrogen peroxide. However, there are no studies with scientific validity that can support its use in a systematic way, and currently, the classic technique presents the best cost / benefit ratio for its safety and predictability.
