- Multi-Mode adhesives performance and success/retention rates in NCCLs restorations: randomised clinical trial one-year reportPublication . Manarte-Monteiro, Patricia; Domingues, Joana; Teixeira, Liliana; Gavinha, Sandra; Manso, Maria ConceiçãoAim: Compare clinical performance and success/retention rates of two multi-mode (MM) adhesives, applied in self-etch (SE) or etch-and-rinse (ER) modes, with SE-all-in-one adhesive (SE/SE with enamel etching) in NCCL restorations at one-year follow-up. Material and methods: Prospective, double-blind RCT approved by the University Fernando Pessoa and the National-Clinical-Research-Ethics Committees (CEIC-20150305), ClinicalTrials.gov registered (NCT02698371), in 38 participants with 210 restorations (AdmiraFusionVR ) randomly allocated to six groups (Adhesives_Adhesion mode), each with 35 restorations: G1-Control FuturabondVRDC_SE; G2-Control FuturabondVRDC_SE with enamel etching; G3-FuturabondVRU_ER; G4-FuturabondVR U_SE; G5-AdheseVR Universal_ER; G6-AdheseVR Universal_SE. Restorations evaluated at baseline and one-year by three calibrated examiners (ICC 0.952) using FDI criteria and statistical analysis with nonparametric tests (alpha=0.05). Results: At one-year recall 36 participants, 199 restorations were available for examination; five (2.5%) restorations (G1 n=2; G2, G3, G4 n=1) were lost due to retention (p>.05); G1 showed less satisfying marginal adaptation (p<.05) than G2 and MM adhesives groups, particularly G6. Overall success rates (p>.05) were: 93.9% (G1), 97.0% (G2; G3; G4) and 100.0% (G5; G6). Conclusions: MM adhesives (FuturabondVRU and AdheseVR Universal) showed similar and acceptable performance/success rates but also better clinical outputs than the SE-all-in-one adhesive (FuturabondVR DC), particularly in SE mode. Success and retention rates were similar and not dependent on materials or adhesion modes.
- Restaurações de fracturas coronárias de dentes anterioresPublication . Melo, Paulo; Domingues, Joana; Teixeira, Liliana; Manarte-Monteiro, Patricia; Monteiro, BeatrizNowadays crown fractures of anterior teeth are getting more common in children and teenagers. These kinds of accidents can affect them for the rest of them lives, behalf of their age, gender or socioeconomic status. This is one of the reasons why dentists are always trying to find different solutions for the treatment of these cases. Mainly in anterior teeth fractures involving enamel or enamel and dentin, one has the direct restoration solution, using composite resin. In this case, the introduction of the “self-etch” technique, and the evolution of adhesive systems and the better physical and aesthetic behaviour of the composite resins, lead to better results. Thus, one can consider the direct restoration as a valid solution that can be done quickly and still is aesthetic and as an excellent clinical behaviour. The authors present a clinical case of an extended traumatic fracture treated with a micro-hibrid composite resin.
- Técnica para obtenção do ponto de contacto em restaurações de classe II com compósitoPublication . Melo, Paulo; Domingues, Joana; Manarte-Monteiro, Patricia; Coelho, Susana; Teixeira, LilianaA criação de um bom ponto de contacto em classes II com compósito, implica a escolha clínica do sistema matriz / cunha mais eficaz para cada caso. Para as situações em que a quantidade de estrutura remanescente está diminuída, os autores desenvolveram uma técnica que facilita a inserção e fixação da matriz para realizar o contorno proximal da restauração. São utilizados os compósitos microhíbridos em conjunto com os condensáveis, para maximizar as propriedades ideais de cada um e assim obter um melhor ponto de contacto.
