RESUMO
Currently, the long-term success of esthetic rehabilitation with ceramics is required. Hence, professional knowledge about the most indicated dental material for each clinical situation as well as its usage protocol is essential. The aim of this systematic review of clinical and laboratorial studies was to compare the bond strength of prostheses using silane incorporated to universal adhesives or applied separately. The literature search in databases "Cochrane Library," "MEDLINE," "Web of Science," "Scopus," "LILACS," "Scielo," and "Google Scholar" was based on the keywords "Silane;" "Silanes;" "Silane coupling agent;" "Universal adhesive;" and "Universal adhesives." A total of five articles were included in this review. In general, the studies showed better results for ceramic etching with hydrofluoric acid and application of silane separately to the universal adhesive. As a conclusion, the treatment with pure silane or as an additional pretreatment with universal adhesives improved the bond strength of glass ceramics. Hence, higher shear bond strength can be achieved, resulting in treatment longevity.
RESUMO
Vascular anomalies (VAs) include a group of distinct lesions, such as vascular system congenital malformations, as well as benign and malignant vascular tumors. These lesions may present similar clinical and histopathological features, leading to mistaken diagnoses and incorrect treatment choices. It is important that professionals responsible for monitoring the development of VAs conduct precise investigations and use the appropriate terminology. The human glucose transporter protein isoform 1 (GLUT1) has been proposed as a tool to aid in differential diagnosis between different VAs, given that it is a sensitive and specific marker for identification of infantile hemangiomas (HIs) in any organ. This article presents a review of the literature on this protein as an effective tool for identification and possible differential diagnosis between several VAs.
As anomalias vasculares (AVs) incluem um grupo de lesões distintas, como as más formações congênitas e os tumores vasculares benignos ou malignos. Estas lesões podem apresentar características clínicas e histopatológicas semelhantes, ocasionando equívocos diagnósticos e terapêuticos. Uma investigação precisa e o uso de terminologia adequada são fundamentais para as decisões do profissional responsável pelo acompanhamento da evolução de uma AV. A isoforma 1 da proteína humana transportadora de glicose (GLUT1) tem sido proposta como uma ferramenta auxiliar para o estabelecimento de diagnóstico diferencial entre AVs, uma vez que representa um marcador sensível e específico para a identificação de hemangiomas da infância de qualquer órgão. Este estudo objetiva fazer uma revisão da literatura acerca desta proteína como ferramenta eficaz na identificação e no possível diagnóstico diferencial entre as diversas AVs.
