Abstract(s)
A preservação e regeneração do complexo dentino-pulpar são cruciais para manter a funcionalidade dos dentes. O alvo é recuperar a polpa dentária, estimular o crescimento do tecido calcificado e prevenir danos adicionais ao tecido pulpar. Salvaguardar a vitalidade dentária é primordial para evitar intervenções mais invasivas. Há uma variedade de materiais disponíveis para preservar o complexo dentino-pulpar, cada um com características específicas, mas todos visando à preservação da saúde dentária, tais como, o Hidróxido de cálcio, o MTA, o Biodentine™, os quais demonstraram mecanismos de regeneração semelhantes quando em contato com a dentina exposta, formando uma ponte dentinária eficaz. Por outro lado, o uso de sistemas adesivos para proteção do complexo dentino-pulpar resultou em achados controversos, com sua eficácia na reparação pulpar ainda não estabelecida. A escolha do material de proteção e regeneração pulpar deve ser feita de acordo com a severidade do dano, o material restaurador utilizado e a espessura entre o teto da câmara pulpar e a base da cavidade.
O objetivo desta revisão narrativa será explorar e avaliar a eficácia dos materiais mais avançados para a proteção e regeneração do complexo dentino-pulpar, fornecendo uma base para práticas clínicas inovadoras e melhoradas, enfatizando suas indicações, vantagens e desvantagens.
Para elaboração deste trabalho, será realizada uma pesquisa bibliográfica nas bases de dados Pubmed/Medline, Google Scholar, recorrendo às seguintes palavras chave: Dentin-pulp complex; Dentin-pulp protection; Calcium hydroxide; MTA; Biodentine™; Pulp regeneration. Será utilizado o operador booleano AND, fazendo diferentes combinações com as palavras. Serão estipulados critérios de inclusão, nomeadamente, artigos publicados nos últimos dez anos (2014-2024), maioritariamente em idioma inglês, mas também em francês e português, contendo informação relevante sobre os materiais utilizados na proteção e regeneração do complexo dentino-pulpar. Poderão ser acrescentadas algumas referências bibliográficas de anos anteriores ao período temporal escolhido, pela sua relevância científica para o enquadramento e compreensão desta temática. Serão excluídos os artigos que após leitura do título ou do resumo não se revelem pertinentes para o tema. Será também considerado como critério de exclusão artigos que não permitam o acesso ao texto integral, ou que não estejam dentro da temática selecionada. Serão aceites todos os tipos de estudos com interesse científico para o trabalho desde revisões narrativas, revisões sistemáticas, ensaios clínicos, estudos in vitro, entre outros.
The preservation and regeneration of the dentin-pulp complex are crucial to maintaining the functionality of teeth. The aim is to recover the dental pulp, stimulate the growth of calcified tissue and prevent further damage to the pulp tissue. Safeguarding tooth vitality is paramount to avoiding more invasive interventions. There are a variety of materials available to preserve the dentin-pulp complex, each with specific characteristics, but all aimed at preserving dental health, such as calcium hydroxide, MTA, Biodentine™, which have demonstrated similar regeneration mechanisms when in contact with exposed dentin, forming an effective dentin barrier. On the other hand, the use of adhesive systems for direct protection of the dentin-pulp complex has resulted in controversial findings, with their efficacy in pulp repair not yet established. The choice of pulp protection/regeneration material should be made according to the restorative material used and the thickness between the roof of the pulp chamber and the base of the cavity. The aim of this narrative review will be to explore and evaluate the effectiveness of the most advanced materials for the protection and regeneration of the dentin-pulp complex, providing a basis for innovative and improved clinical practices by emphasising their indications, advantages and disadvantages. To prepare this study, a bibliographic search will be carried out in the Pubmed/Medline and Google Scholar databases, using the following keywords: Dentin-pulp complex; Dentin-pulp protection; Calcium hydroxide; MTA; Biodentine™; Pulp regeneration. The Boolean operator AND will be used, making different combinations with the words. Inclusion criteria will be stipulated, namely articles published in the last ten years (2014-2024), mostly in English, but also in French and Portuguese, containing relevant information on the materials used in the protection/regeneration of the dentin-pulp complex. Some bibliographical references from years prior to the chosen time period may be added for their scientific relevance to the framework and understanding of this subject. Articles which, after reading the title or abstract, are not relevant to the topic will be excluded. Articles that do not allow access to the full text or that are not within the selected theme will also be considered as exclusion criteria. All types of studies of scientific interest to the work will be accepted, from narrative reviews, systematic reviews, clinical trials, in vitro studies, among others.
