Abstract(s)
As resinas compostas e os sistemas adesivos assumem, na actualidade, um papel central na medicina dentária restauradora, constituindo o alicerce de intervenções cada vez mais conservadoras, tanto do ponto de vista estético como funcional. Todavia, a adesão ao tecido dentinário continua a representar uma das maiores dificuldades clínicas, em virtude da sua natureza morfofuncional complexa e da vulnerabilidade à degradação ao longo do tempo. O presente trabalho de revisão teve como propósito examinar, de forma crítica e fundamentada, os progressos recentes no domínio da formulação de materiais restauradores, bem como os mecanismos implicados na deterioração da interface adesiva. Em paralelo, foram exploradas as estratégias actualmente em desenvolvimento para potenciar a eficácia e prolongar a longevidade das restaurações. Entre os temas abordados, destacaram-se a classificação e evolução das resinas compostas, os fundamentos da adesão à dentina, os diferentes tipos de sistemas adesivos disponíveis e as tendências emergentes, que englobam o uso de materiais biomiméticos, a aplicação de nanotecnologia e o recurso a compósitos autoadesivos. Com base na análise da literatura, verificou-se que, apesar das melhorias substanciais no desenvolvimento de novos materiais restauradores, a durabilidade clínica das restaurações continua a depender de uma multiplicidade de factores. Entre estes incluem-se a escolha criteriosa do material, a técnica operatória adotada e as particularidades do ambiente clínico em que a restauração é realizada. Neste contexto, conclui-se que a prática restauradora actual exige uma abordagem que seja baseada em evidências científicas robustas, associada a uma actualização contínua dos conhecimentos técnico-científicos por parte dos profissionais.
Esta integração de conhecimento, tecnologia e competência clínica é fundamental para garantir o sucesso terapêutico das intervenções restauradoras e para promover uma evolução sustentada, segura e eficaz na medicina dentária contemporânea.
Resin composites and adhesive systems currently play a central role in restorative dentistry, forming the foundation for increasingly conservative interventions from both aesthetic and functional perspectives. Nevertheless, achieving reliable adhesion to dentine remains one of the most significant clinical challenges, due to its complex morphofunctional nature and susceptibility to long-term degradation. This literature review aimed to critically and thoroughly examine recent advances in the formulation of restorative materials, as well as the mechanisms involved in the degradation of the adhesive interface. Additionally, it explored current strategies being developed to enhance the effectiveness and extend the longevity of restorations. Topics covered included the classification and evolution of composite resins, the principles of dentine adhesion, the range of available adhesive systems, and emerging trends such as the use of biomimetic materials, the application of nanotechnology, and the development of self-adhesive composites. Based on the analysis of the literature, it was found that despite substantial improvements in the development of new restorative materials, the clinical durability of restorations still depends on a multifactorial interaction. Key factors include the careful selection of the restorative material, the operative technique used, and the specific clinical context in which the procedure is performed. In this light, it is concluded that modern restorative practice requires an approach grounded in robust scientific evidence, combined with the continuous updating of technical and scientific knowledge by dental professionals. This integration of knowledge, technology, and clinical skill is essential to ensure the therapeutic success of restorative procedures and to foster a sustainable, safe, and effective evolution in contemporary dentistry.
