Temporal oral microbiome changes with brushing in children with cleft lip and p...
Rodrigues, Rita; Chung, Ana P.; Mortensen, Martin S.; Fernandes, Maria H.; Monteiro, António B.; Furfuro, Rowney; Silva, Cátia C.; Manso, Maria C.This cohort study aimed to characterize the oral microbiome of children with CLP, from two different age groups, and evaluate the effect of supervised or unsupervised toothbrushing on the microbiome of the cleft over time. Swab samples were collected from the cleft area at three different time points (A; no brushing, B; after 15 days and C; after 30 days) and were analyzed using next-generation sequencing to de...
Bond strength of metallic or ceramic orthodontic brackets to enamel, acrylic, o...
Pinho, Mónica; Manso, Maria C.; Almeida, Ricardo Faria; Martin, Conchita; Carvalho, Óscar; Henriques, Bruno Alexandre Pacheco de CastroBonding strategies within different brackets and dental materials are still a challenge concerning adhesion and dental surface damage. This study compared the shear and tensile bond strength of orthodontic ceramic and metallic brackets to enamel, acrylic, and ceramic surfaces after thermal cycling. Dental surfaces were divided into three groups: enamel, ceramic, and acrylic. Each group received stainless-steel ...
Modelling ascorbic acid thermal degradation and browning in orange juice under ...
Manso, Maria C.; Oliveira, Fernanda A.R.; Oliveira, Jorge C.; Frías, Jesús M.The thermal degradation of ascorbic acid (AA) in orange juice was analysed over in a 20–45 °C temperature range. Dehydroascorbic acid (DA), pH and browning were also monitored. Small amounts of AA degradation could be described by first order kinetics, but when only low amounts of AA were retained sigmoidal kinetics were clearly appropriate. The Weibull model was used to describe this pattern (R2adj > 0.995). T...
