Longevity of restorations in direct composite resin: literature review

The objective of the present work was to conduct a literature review on the clinical performance of different types of composite resins and adhesive systems with regard to longevity. For this evaluation, some characteristics of the restorations were immediately verified after they were completed and after a determined time. Characteristics such as postoperative sensitivity, color, marginal integrity, secondary caries, texture, marginal adaptation, retention, displacement, marginal discoloration and anatomical shape had their performances compared. The influence of different adhesive systems on the longevity of the restorations was also observed as a function of its fundamental importance in the union between the tooth and the restorative material. It was concluded that most restorations performed clinically acceptable when hybrid, nanoparticle or microhybrid composite resins and conventional adhesive systems were used.RESUMO As restaura ções de resinas compostas têm aumentado consideravelmente em popularidade e previsibilidade, possibilitando a realização de um tratamento odontológico minimamente invasivo. No entanto, para se obter o sucesso das restaurações de resina composta é necessário ter conhecimento dos materiais a desivos e da técnica de utilização, caso contrário os insucessos podem aparecer rapidamente. Assim, o objetivo deste trabalho foi realizar uma revisão de literatura sobre o desempenho clínico de diferentes tipos de resinas compostas e de sist...
