Abstract(s)
A erosĆ£o dentĆ”ria Ć© caracterizada pela dissoluĆ§Ć£o irreversĆvel dos tecidos mineralizados dos dentes. A origem das lesƵes pode ser intrĆnseca, como Ć© o caso das lesƵes provocadas por Ć”cido gĆ”strico em pacientes com doenƧa de refluxo gastroesofĆ”gico, ou extrĆnseca, quando provocadas por Ć”cidos presentes na dieta alimentar. De acordo com a origem e com o grau de severidade da lesĆ£o, elege-se a estratĆ©gia terapĆŖutica atravĆ©s de uma combinaĆ§Ć£o apropriada de aƧƵes preventivas e/ou restauradoras. Atualmente, quando sĆ£o necessĆ”rios tratamentos restauradores, a escolha deve recair sobre a abordagem minimamente invasiva e aditiva. Portanto, esta revisĆ£o de literatura teve como objetivo discutir o atual panorama da estabilidade de uniĆ£o dos sistemas adesivos em dentes erodidos, jĆ” que esta etapa Ć© crucial para o sucesso e longevidade da terapia restauradora.
Foi elaborada a pergunta PICO (Paciente ou Problema; IntervenĆ§Ć£o; ComparaĆ§Ć£o; Outcome): āForƧas de adesĆ£o a dentes erodidos sĆ£o diferentes das forƧas de adesĆ£o a dentes nĆ£o erodidos?ā, e realizou-se uma pesquisa bibliogrĆ”fica nas bases de dados MedLine/Pubmed, Library e ScienceDirect. Encontraram-se 68 artigos publicados em inglĆŖs, entre 2009 e 2020, com o uso de palavras-chave com ou sem combinaƧƵes. ApĆ³s aplicaĆ§Ć£o dos critĆ©rios de inclusĆ£o/exclusĆ£o foram selecionados 8 artigos para a revisĆ£o.
Concluiu-se que a dentina erodida prejudica a resistĆŖncia de uniĆ£o dos sistemas adesivos a longo prazo, o que nĆ£o foi observado no caso do esmalte dentĆ”rio. Desta maneira, foi sugerido o uso de adesivos com a tĆ©cnica self-etch na adesĆ£o a dentina erodida.
Dental erosion is characterized by the irreversible dissolution of the mineralized tissues of the teeth. The origin of the lesions can be intrinsic, as is the case of wear caused by gastric acid in patients with gastroesophageal reflux disease, or extrinsic, when caused by acids present in the diet. According to the etiology and the severity of the lesion, the therapeutic strategy is chosen through an appropriate combination of preventive and/or restorative actions. Currently, when there are areas treated with restoration, the choice should fall on the minimally invasive and additive approach. Therefore, this literature review aimed to discuss the current panorama of the bonding stability of adhesive systems in eroded teeth, as this step is crucial for the success and longevity of restorative therapy. A PICO search question (Patient/Problem; Intervention; Comparison; Outcome): āBond strength in eroded teeth is different from that of non-eroded teeth?ā was established and a bibliographic research was carried out in the MedLine / Pubmed, Library and ScienceDirect databases. Sixty-eight papers published in English, between 2009 and 2020, were found using keywords with or without templates. After application of inclusion and exclusion criteria, 8 articles were selected for the review. It was concluded that the long term results of bond strength to eroded dentine are worse than those to sound dentine. Erosion does not seem to affect the bond strength to enamel. The literature suggests the use of self-etch adhesives, when adhering to eroded teeth.
