A new hotel classification model combining guest reviews with official hotel cl...
Messias, Ana; Rosa, Gilberto; Couto, Pedro; Rodrigues, Vítor; Silva, Luís M.; Marques, JorgeThis paper explores the potential of combining online guest reviews with hotel classification systems, focusing on the feasibility of incorporating such reviews at the star-classification level. Leveraging machine learning techniques on a database of Portuguese hotels and their corresponding ratings on Booking.com, this study reveals a weak association between official hotel star categories and mean review scor...

Surface Roughness Evaluation of Resin Composites after Finishing and Polishing ...
Vinagre, Alexandra; Barros, Catarina; Gonçalves, Joana; Messias, Ana; Oliveira, Filipe; Ramos, JoãoThe purpose of this study was to evaluate the effect of two finishing and polishing methods on the surface roughness of different resin composites. Twenty-two disk-shaped specimens of five resin composites Zirconfill® (ZF), Filtek™ Supreme XTE (FS), Brilliant EverGlow™ (BG), Ceram.X® Duo (CD), and Harmonize™ (HA) were prepared for each one using a silicon mold. Both surfaces of each specimen were first grinded ...
Transport Properties of Carbohydrates: Towards the Minimization Toxicological R...
Trindade, Ana C. V.; Fangaia, Sónia I. G.; Nicolau, Pedro M. G.; Messias, Ana; Ribeiro, Ana C. F.; Silva, Daniela S. A.; Valente, Artur J. M.The influence of oligosaccharides ( -cyclodextrin, -cyclodextrin and -cyclodextrin), and a polysaccharide, sodium hyaluronate (NaHy), on the diffusion of aqueous solutions of cobalt and chromium chlorides has been investigated. Cobalt and chromium are constituents of metal alloys for biomedical use, including dental prostheses. Thus, the release of these ions in the human body can lead to harmful biological eff...
Physicians' perceptions of psychosocial factors and coping strategies in their ...
Messias, Ana; Estrela, Marta; Couto, Pedro; Sá-Couto, Pedro; Ramos, MarcoBackground/Objective: Physicians play a crucial role in healthcare systems but face negative impacts from a challenging work environment, leading to burnout. Burnout has negative effects on physician health and patient care. Understanding psychosocial aspects of work and coping strategies used by physicians is essential. Validated tools, including COPSOQ-II, BriefCOPE, and WAI scales, can provide insight into t...

The Effectiveness of Dental Protection and the Material Arrangement in Custom-M...
Messias, Ana; Gomes, Inês J.; Reis, Paulo N. B.; Amaro, Ana M.; Neto, Maria A.Experimental research studies have shown that wearing a mouthguard (MG) is an effective way to prevent tooth or maxillofacial trauma. However, there is a lack of scientific information regarding how the material arrangement within the mouthguard can modify its mechanical response during an impact. Hence, this study aimed to evaluate the influence of material arrangement within custom-made mouthguards on stress ...
Mechanical Evaluation of Implant-Assisted Removable Partial Dentures in Kennedy...
Messias, Ana; Neto, Maria A.; Amaro, Ana M.; Lopes, Vítor M.; Nicolau, PedroThe main purpose of this work was to construct a clinically valid numerical model of a mandibular Kennedy class I patient rehabilitated with a conventional removable partial denture and another two with implant-assisted removable partial dentures at two different implant locations. The selected patient was classified as ASA I and its mandible geometry reconstruction was performed by the conversion of the Cone-B...
Impact response of different materials for sports mouthguards
Reis, P. N. B.; Amaro, Ana Paula; Neto, Maria Augusta; Messias, Ana; Ramos, João Carlos; Moreira, MariaUp to this moment, there is no guideline regarding the materials to produce mouthguards. The most used is Ethylene-Vinyl Acetate (EVA). Studies indicate that laminating EVA sheets with rigid components could increase the protection capacities of the mouthguards. On the other hand, other studies suggest that only replacement of the material within its structure can increase energy absorption. Therefore, this wor...
