Carvalho, Ana Lidia; Daniela Gavinha Da Costa, Liliana; Martins, Joana Meneses; Manso, M. Conceição; Gavinha, Sandra; Herrero-Climent, MarianoThe present study had a convenience sample with 236 laypeople and 242 dentists who completed an online questionnaire to choose the most attractive image among six pairs for comparison. Control image: symmetric (parallelism between occlusal plane (OP), commissural line (CL), and interpupillary line (IL)). Change of Control, obtaining three images with a 3-degree inclination of the labial commissures. Image A: OP...
Bacterial contamination of gutta-percha points from different brands and the ef...
Bracciale, Francesca; Marino, Nicole; Noronha, Anariely; Manso, M. Conceição; Gavinha, Sandra; Cardoso, Inês LopesObjective: To evaluate the bacterial contamination of different brands of Gutta-Percha (GP) points routinely used in clinical practice and the efficacy of a chairside disinfection protocol with sodium hypochlorite. Methods: GP points (n=240), in sizes A, B, C, D, K15, K20, K25, K30, K35, K40, F1, F2, F3 (Dentsply®, Proclinic®, ProTaper® and R&S®), were randomly sampled from commercial packages already in use. T...
Detection of Staphylococcus aureus (MRSA/MSSA) in surfaces of dental medicine e...
Gonçalves, Eva; Carvalhal, Rui; Mesquita, Rita; Azevedo, Joana; Coelho, Maria João; Magalhães, Ricardo; Ferraz, Maria Pia; Manso, M. ConceiçãoMethicillin-Resistant Staphylococcus aureus (MRSA) represents one of the major causes of nosocomial infections, leading to high mortality. Surfaces in clinics, as well as the attending uniform and the hands of the dental doctor can be MRSA reservoirs. Having this in mind, the purpose of this study was to evaluate the presence of Methicillin-Sensitive Staphylococcus aureus (MSSA) and MRSA on dental medicine equi...
Multi-Mode adhesives performance and success/retention rates in NCCLs restorati...
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...
Effect of thermal cycling on the shear bond strength of different orthodontic a...
Neto, Vando; Pinho, Monica; Henriques, Bruno Alexandre Pacheco de Castro; Silva, Filipe Samuel; Gavinha, Sandra; Sousa, JulioObjective: The aim of this study was to assess the influence of thermal cycling on the shear bond strength of three types of adhesives used for orthodontic brackets to human enamel.Methods: Sixty six human premolars were used in this study. Two groups of dental resin composite adhesives (ED; G) and one compomer (TP) were thermal cycled from 5 up to 55 degrees C at 4000 cycles for 45 s in an artificial saliva so...
Abrasive and sliding wear of resin composites for dental restorations
Souza, J. C. M.; Bentes, Ana Catarina Fernandes; Reis, Kelly; Gavinha, Sandra; Buciumeanu, Mihaela; Henriques, Bruno; Silva, Filipe Samuel; Gomes, J. R.The aim of this work was to study the abrasive and reciprocating sliding wear resistance of four commercial resin composites for dental restorations. Resin composite samples were divided into four groups considering the different materials and then separated for compressive, abrasive and sliding tests (n=10). Micro-abrasion tests were performed against a stainless steel rotating ball on 3 N normal load for 300 ...
