- Prevalence of periapical lesions, root canal treatments and restorations in teeth adjacent to implant- or toothsupported crownsPublication . Baruwa, Abayomi O.; Martins, Jorge N. R.; Ginjeira, AntónioAim: To describe the prevalence of periapical lesions, root canal treatments and coronal restorations on teeth adjacent to either implant- or natural tooth-supported crowns using cone-beam computed tomography (CBCT) assessment compared to nonadjacent teeth. Methodology: A total of 1249 CBCT volumes were screened by five pre-calibrated observers in 11 health centres. A step-by-step screening protocol was implemented and reviewed every 3 months, and mandatory setting characteristics were established for all CBCT scans using dedicated visualization software. Intra- and inter-rater reliability tests were conducted. The prevalence of periapical lesions, root canal treatments and coronalrestorations wasrecorded on both teeth adjacent and nonadjacent to implant- (predictor 1) or natural tooth-supported crowns (predictor 2). A binary logistic model (Generalizing Estimating Equations test) was used to verify whether the prevalence of periapical lesion, root canal filling and the tooth restorative status are altered when the assessed tooth is adjacent or not to an implant-supported crown (predictor 1); or to a natural tooth-supported crown (predictor 2). Odds ratio and confidence intervals for the dependent variables at both predictors were obtained. The significance level was set at .05. Results: A global sample of 22 899 teeth was included. Compared to nonadjacent teeth, the prevalence of periapical lesion, root canals treatments and restorative procedures when adjacent to implant-supported crowns was 10.7%, 19.6% and 22.9% higher, respectively, and when adjacent to tooth-supported crowns was 19.3%, 35.6% and 37.4% higher respectively. These results were significant only for variables root canal filling and coronal restoration (p < .0001). Odds ratio to present root canal treatment is 2.57 times higher (CI 1.95–3.39, p = .0001) when the tooth is adjacent to implant-supported crown and 4.39 times (CI 3.49–5.53, p = .0001) when adjacent to tooth-supported crown, whilst for restorative procedure, the odds are, respectively, 1.63 (CI 1.29–2.06, p = .0001) and 2.30 (CI 1.92–2.76, p = .0001).
- Prevalence of bruxism in adults with cerebral palsy institutionalized in LisbonPublication . Cabrita, Joana P.; Quaresma, Maria Carlos; Bizarra, Maria de FátimaBased on the high prevalence of bruxism in the sample, there was an urgent need for the implementation of treatment options for this pathology in people with CP, in order to try to prevent its harmful consequences on the stomatognathic system. In this study active wear facets were observed in the majority of the sample. Through alogistic regression it was found that the risk of having MB and GB is greater in individuals who have shiny wear facets. More studies are needed with standardized diagnostic protocols and representative samples to evaluate the factors that influence the presence of bruxism in this population and to establish an appropriate treatment planning.
- Understanding how and why people participate in crowd eventsPublication . Costa-Lopes, Rui; Torres, Eduardo Cintra; Moreira, SérgioThe participation and collective effervescence in crowd events is a perennial issue in social sciences, however it has scarcely been researched from the point of view of the attendees. This article helps to fill the gap with an exploratory descriptive study based on a sample of 1,553 respondents from 40 countries. The authors analyse seven different types of events and also describe the various participation levels, whether people go there alone or in company, and their reasons for attending. Globally, the results show several specific patterns: (a) the majority of the participants often go to collective events, but different events have different levels of participation; (b) people rarely go alone to collective events, but the company depends on the type of event; (c) although the results show it is not necessary to like the event to trigger participation, people have different reasons for going to different events. The article concludes with a cluster analysis that details the links between attendance, company, and reasons to attend, according to the socio-demographic factors.
- Development of a Digital Repository Prototype applied to Faculty of Pharmacy, University of LisbonPublication . Lopes, Sílvia Costa; Lopes, Pedro Faria; Campos, FernandaUniversity libraries have played a key role in scientific research as well as in the support of education-related activities. Their main goal is to provide their users with immediate access to relevant information through updated information sources. Science evolves rapidly and so the daily information needs on health matters are large and require rapid access to the sources. One of the problems that currently exist in university libraries is the access and processing of information in digital format. Digital objects are technologically diverse and there is not enough technical information regarding its proper handling. In this paper we present the tools and methodologies that should be used to provide, in an organized and validated way, the wide range of existing information in a digital format. This work was done in the context of a Master of Science thesis in Information Studies and Digital Libraries. The aim was to find practical solutions for the processing and offering of information in digital format in the context of pharmaceutical sciences. Finally, the paper presents reliable benchmarking of best practices to implement and evaluate a prototype applied to the Pharmaceutical Sciences, in order to satisfy the user’s needs.
- Archives in Web 2.0: new opportunitiesPublication . Nogueira, Marta, 1977-Archives are using Web 2.0 applications in a context that allows for new types of interaction, new opportunities regarding institutional promotion, new ways of providing their services and making their heritage known to the community. Applications such as Facebook (online social network), Flickr (online image-sharing community) and YouTube (online video sharing community) are already used by cultural organisations that interact in the informal context of Web 2.0. In this article I aim to describe how Web 2.0 can work as a virtual extension for archives and other cultural organisations, by identifying impacts and benefits resulting from the use of Web 2.0 applications together with some goals and strategies of such use.
