The 100 most-cited articles in orthodontics: A bibliometric study
2018
ABSTRACT Objectives: To identify and analyze the 100 most-cited articles in orthodontics indexed in the Web of Science Category of “Dental, Oral Surgery and Medicine” from 1946 to 2016. Materials and Methods: On hundred articles were identified in a search of the database of the ISI Web of Science and Journal Citation Reports, applying the truncated search term “orthodon*.” Records were manually refined and normalized to unify terms and to remove typographical, transcription, and/or indexing errors. Results: The 100 most-cited articles were published between 1946 and 2012, with numbers of citations ranging from 115 to 881. Of the 251 authors participating, 87.65% published a single work, wh…
Mechanical properties of provisional dental materials: A systematic review and meta-analysis
2018
Provisional restorations represent an important phase during the rehabilitation process, knowledge of the mechanical properties of the available materials allows us to predict their clinical performance. At present, there is no systematic review, which supports the clinicians' criteria, in the selection of a specific material over another for a particular clinical situation. The purpose of this systematic review and meta-analysis was to assess and compare the mechanical properties of dimethacrylates and monomethacrylates used in fabricating direct provisional restorations, in terms of flexural strength, fracture toughness and hardness. This review followed the PRISMA guidelines. The searche…
Orthodontic brackets friction changes after clinical use : a systematic review
2019
Background To evaluate the bracket-wire friction force after clinical use. Material and methods A systematic search of several electronic databases (PubMed, Embase, Web of Science, Scopus, The Cochrane Library, Lilacs and Google Scholar) without limitations regarding publication year or language, was performed. In-vitro studies analyzing the changes in friction force of orthodontic brackets before/after their clinical use were considered. Risk of Bias was assessed with Downs and Black checklist. All methodological features that could interfere in the results were specifically described. Results Seven studies satisfied the inclusion criteria and were included in the review. All 7 studies rep…
The retention characteristics of Hawley and vacuum-formed retainers with different retention protocols
2018
Background This study aimed to compare the effectiveness of two different protocols of wearing vacuum-formed retainers (VFRs) with the standard protocol of wearing Hawley retainer in maintaining the results of orthodontic treatment. Material and Methods This single-blind randomized clinical trial consisted of 90 patients who finished orthodontic treatment at the Department of Orthodontics of Mashhad Dental School, and required removable retainers. The participants were randomly divided into 3 groups and received the following treatments. Group 1: Hawley retainers (4 months full-time and then night-only); group 2: VFR_4M (4 months full-time and then night-only); group 3: VFR_1W (1 week full-…
Exercise and Healthy Eating Intentions and Behaviors among Normal Weight and Overweight/Obese Adults
2016
Strong evidence suggests that exercise and eating behaviours are strongly linked. Theory of Planned Behaviour is a theoretical framework that has been successfully used to explain and predict both behaviours. The aim of the present study is to explore the constructs of Theory of Planned Behavior (TPB) that better predicts exercise and healthy eating: a) intentions and b) selfreported behaviors among normal weight and overweight/obese adults. Participants were 361 adults in Greece (women: N = 152). According to their BMI scores, they have been grouped into normal weight and overweight/obese. Data were collected with an online questionnaire assessing variables of the theory of planned behavio…
Improvement of the Valencia region ultraviolet index (UVI) forecasting system
2012
The CEAM Foundation (Valencia, Spain) has developed an operational ultraviolet index (UVI) forecasting system based on the Santa Barbara DISORT Atmospheric Radiative Transfer (SBDART) model. The main objective of this system is to provide the general public with a tool to minimize the impact of ultraviolet (UV) radiation, which can cause important human health problems. The system presented in this paper has been developed in collaboration with the Environment Department of the Regional Government of Valencia, and it replaces the one running until 2007. The new system substitutes the previously used Ozone Monitoring Instrument (OMI) observed data with the total ozone column data forecasted …
DiDuSoNet: A P2P architecture for Ditributed Dunbar-based Social Networks,
2015
Online Social Networks (OSNs) are becoming more and more popular on the Web. Distributed Online Social Networks (DOSNs) are OSNs which do not exploit a central server for storing users data and enable users to have more control on their profile content, ensuring a higher level of privacy. In a DOSN there are some technical challenges to face. One of the most important challenges is the data availability problem when a user is offline. In this paper we propose DiDuSoNet, a novel P2P Distributed Online Social Network where users can exercise full access control on their data. Our system exploits trust relationships for providing a set of important social services, such as trustness, informati…
Drivers affecting the adoption and effectiveness of social media investments: The Italian wine industry case
2019
Purpose The purpose of this paper is twofold: first, to identify distinct organisational models in a sample of firms operating in the wine industry; and second, to identify the main internal resources that characterise those firms most motivated towards the adoption of social media (SM) tools and those that perceive SM investment as more effective. Design/methodology/approach The empirical investigation was carried out by administering an online questionnaire to a sample of 82 Sicilian wineries. The principal component analysis was used to identify latent factors that drive managers to invest in SM technologies and to measure the impact perceived by managers. Subsequently, a cluster analys…

Bridging data mining and semantic web
2016
Nowadays Semantic Web is widely adopted standard of knowledge representation. Hence, knowledge engineers are applying sophisticated methods to capture, discover and represent knowledge in Semantic Web form. Studies show that, to represent knowledge in Semantic Web standard, data mining techniques such as Decision Trees, Association Rules, etc., play an important role. These techniques are implemented in publicly available Data Mining tools. These tools represent knowledge discovered in human readable format and some tools use Predictive Model Markup language (PMML). PMML is an XML based model for data mining model representation that fails to address the representation of the semantics of t…
