Abstract(s)
A estética do sorriso tem um lugar cada vez mais importante na sociedade moderna. As manchas presentes nos dentes estão na origem da insatisfação por parte do paciente, razão pela qual a utilização e o mercado dos dentífricos branqueadores, se desenvolveu extremamente ao longo dos últimos anos.
Este trabalho teve como objectivo realizar uma revisão narrativa da literatura sobre a evidência existente sobre a composição, acção e eficácia das pastas de dentes branqueadoras e discutir as consequências da sua utilização. Para tal, foram pesquisados artigos em bases de dados eletrónicas como a PubMed, Science Direct e B-On, com critérios de inclusão bem definidos.
As mudanças de cor decorrentes da utilização de pastas dentífricas branqueadoras não são fáceis de objectivamente se contabilizarem, dada a dificuldade em medir cor dentária e em isolar a ação dos diferentes agentes. Os estudos divergem muito na metodologia, o que não permite determinar com evidência científica o agente mais eficaz. A associação entre os agentes abrasivos e químicos aparenta ter resultados mais promissores, desde que não sejam pacientes de risco (importante a quantificação de desgaste dentário, e de sensibilidade dentária).
Serão necessários mais e melhores estudos sobretudo sobre a eficácia e segurança das pastas de carvão activado, para que a pressão comercial não se sobreponha à evidência científica e à utilidade clínica.
Smile aesthetics has an increasingly important place in modern society. The stains present on teeth are at the root of patient dissatisfaction, which is why the use and market of whitening toothpastes has developed greatly in recent years. This study aimed to conduct a narrative review of the literature on the existing evidence on the composition, action and efficacy of whitening toothpastes and to discuss the consequences of their use. To this end, articles were searched in electronic databases such as PubMed, Science Direct and B-On, with well-defined inclusion criteria. Colour changes resulting from the use of whitening toothpastes are not easy to objectively account for, given the difficulty in measuring tooth colour and isolating the action of diferente agents. Studies differ widely in methodology, which makes it impossible to determine with scientific evidence the most effective agent. The association between abrasive and chemical agents seems to have more promising results, provided that the patients are not at risk (it is important to quantify dental wear and sensitivity). More and better studies are needed, especially on the efficacy and safety of activated carbon pastes, so that commercial pressure does not override scientific evidence and clinical usefulness.
