Abstract(s)
O branqueamento dentário é um procedimento que visa branquear os dentes, deixando-os com uma cor mais agradável, melhorando a estética do sorriso.
A procura por um sorriso mais branco leva muitos pacientes à consulta de medicina dentária.
Este tratamento promove a remoção das manchas dos dentes através da oxidação dos pigmentos, sendo o agente branqueador mais utilizado o Peróxido de Hidrogénio. Há variadas formas de aplicação deste tratamento, nomeadamente branqueamento externo em consultório, em ambulatório ou produtos de venda livre como as pastas branqueadoras, colutórios, pinceis com gel branqueador, tiras branqueadoras, entre outros. Antes de se efetuar um branqueamento dentário, é de extrema importância que haja uma correta avaliação por parte de um médico dentista, de forma a que o tratamento seja o mais eficaz e adequado possível ao paciente, uma vez que este tratamento pode ter consequências nefastas para o dente, nomeadamente, sensibilidade dentária, efeitos na microdureza do esmalte, irritação dos tecidos moles. Estes são alguns dos efeitos secundários mais relatados.
Assim, e no sentido de diminuir os efeitos causados pelo branqueamento dentário, foram propostas várias soluções, como por exemplo a utilização de fosfato de cálcio amorfo.
Deste modo, e através de revisão da literatura científica, o objetivo deste trabalho é a conceção de um estudo que permita avaliar a mineralização e a microdureza da camada superficial do esmalte submetido a tratamento com branqueamento dentário, que inclui fosfato de cálcio amorfo na sua composição.
Tooth whitening is a procedure that aims to whiten teeth, leaving them with a more pleasant color, improving the smile aesthetics. Indeed, the search for a whiter smile, takes many patients to a dental appointment. This treatment promotes the removal of stains from the teeth through the oxidation of the pigments, being Hydrogen Peroxide the bleaching agent most commonly used. There are several ways of applying this treatment, namely, external bleaching in a doctor's office, at home or over-the-counter products such as bleaching pastes, mouthwashes, brushes with bleaching gel, bleaching strips, among others. Dental bleaching can have harmful consequences for tooth. The most frequently reported side effects are dental sensitivity, effects on the microhardness of the enamel and soft tissues irritation. Therefore, prior to performing a dental bleaching, the patient should consult a dentist to select the most appropriate and effective type of treatment. In this perspective, to diminish the harmful effects caused by tooth whitening, several alternative solutions have been proposed, including the use of amorphous calcium phosphate. Considering an extensive review of the scientific literature performed, the objective of this work was the development of a study to evaluate the mineralization and microhardness of the superficial layer of enamel submitted to treatment with tooth whitening, which includes amorphous calcium phosphate in its composition.
