Luting of ceramic crowns with a self-adhesive cement: Effect of contamination on marginal adaptation and fracture strength
2012
Objectives: This study evaluated the percentages of continuous margins (%CM) and fracture strength (FS) of crowns made out from blocs of leucite-reinforced ceramic (IPS Empress CAD) and luted with a representative self-adhesive cement (RelyX Unicem) under four contaminating agents: saliva, water, blood, a haemostatic solution containing aluminium chloride (pH= 0.8) and a control group with no contamination. Study Design: %CM at both tooth-cement (TC) and cement-crown (CC) interfaces were determined before and after a fatigue test consisting of 600’000 chewing loads and 1’500 temperature cycles changing from 5º C to 50º C. Load to fracture was recorded on fatigued specimens. Kruskal-Wallis t…
Oral colonization by Levilactobacillus brevis KABPTM-052 and Lactiplantibacillus plantarum KABPTM-051: A Randomized, Double-Blinded, Placebo-Controll…
2021
Background To determine the oral colonization capacity of the strains Levilactobacillus brevis KABPTM-052 (CECT 7480) and Lactiplantibacillus plantarum KABPTM-051 (CECT 7481) in healthy subjects. Material and methods This randomized, double-blinded, placebo-controlled study included 40 volunteers (22 females, 18 males; age range 18-55 years) with healthy gingiva or mild gingivitis, allocated to receiving probiotic chewing gum (n=20) or placebo (n=20) b.i.d for 6 weeks. At baseline and after 6 weeks of treatment, a periodontics specialist collected saliva samples to assess probiotic colonization by qPCR, and analysed dental plaque, gingival index and dental probing pocket depth in Community …
Treatment of Gingival Recession: When and How?
2021
Gingival recession is a common finding in daily clinical practice. Several issues may be associated with the apical shift of the gingival margin such as dentine hypersensitivity, root caries, non-carious cervical lesions (NCCLs), and compromised aesthetics. The first step in an effective management and prevention program is to identify susceptibility factors and modifiable conditions associated with gingival recession. Non-surgical treatment options for gingival recession defects include establishment of optimal plaque control, removal of overhanging subgingival restorations, behaviour change interventions, and use of desensitising agents. In cases where a surgical approach is indicated, co…
Topics and techniques in clinical supervision in psychotherapy training
2017
AbstractClinical supervision is regarded as one of the most important components of psychotherapy training. In clinical practice, it has been found that the implementation of clinical supervision varies substantially and often differs from the recommendations made in the literature. The objective of the current study was to investigate the frequency of topics (e.g. ethical issues) and techniques (e.g. role play) in the clinical supervision of psychotherapy trainees in Germany. To this end, we considered supervisions in cognitive behavioural therapy (CBT) and psychodynamic therapy (PT). A total of 791 psychotherapy trainees (533 CBT and 242 PT) were asked via the internet to provide informat…
Assessing therapist development: Reliability and validity of the Supervisee Levels Questionnaire (SLQ-R).
2019
BACKGROUND Therapist development is a crucial target for clinical training in order to ensure high-quality psychotherapy. A major challenge in examining therapeutic development is the assessment of developmental processes. The Supervisee Levels Questionnaire (SLQ-R) was analyzed in this study to examine its validity, reliability, and underlying dimensional structure. METHOD Seven hundred and sixty therapists participated in an online survey concerning their current psychotherapy training. The factor structure as well as the validity of the SLQ-R were investigated using exploratory and confirmatory factor analysis. RESULTS In line with the results of the exploratory factor analyses, a Bifact…
Fine slicing of the value chain and offshoring of essential activities: empirical evidence from European multinationals
2014
The offshoring of more advanced activities is increasing and a debate about the limits of offshoring has emerged. Companies are fine-slicing their value chains, and moving beyond the offshoring of peripheral and non-core activities to the offshoring of advanced and essential activities that are closer to their core (e.g. research, design and product development). The challenge is to understand the limits of offshoring and the most appropriate modes of offshoring. The purpose of this paper is to analyze what activities are offshorable and how best to govern offshored activities. We argue that companies are redefining their core activities and in this process, some essential activities previo…
PIRACY REVISITED: EXPLORING MUSIC USERS IN THE AGE OF TECHNOLOGY DEPENDENCY
2019
This paper empirically investigates and characterizes users of recorded music, both downloaders and purchasers. To this end we analyse the role of the variables defining the different segments of music users. In doing so, we have considered two main traits influencing the use of music. First, objective variables such as demographics, music consumption habits, music genres and technology. Second, subjective variables such as motives and attitudes towards piracy. Using data from a personal survey, subsequent latent class and fuzzy analyses show that while the former characteristics are relevant in those getting music for free from the Internet, the latter don´t pay any special part, contrary …

Main components of the corporative image of cultural organizations
2016
[EN] In the present research, we carry out an analysis of the corporate image of a cultural organization which aims tohighlight its role in order to design management strategies in the cultural field. We investigate what particular attributes are better assessed by the public and which dimensions compose the corporate image of a cultural organization. Based on the literature review, we made an in-depth interview to the programming manager of a cultural organization and also a descriptive survey on its audience through a structured questionnaire.The results of the analyses show that the corporate image of the cultural organization under study is positive, although someattributescan be improv…
Personalized management of dyslipidemias in patients with diabetes-it is time for a new approach (2022)
2022
AbstractDyslipidemia in patients with type 2 diabetes (DMT2) is one of the worst controlled worldwide, with only about 1/4 of patients being on the low-density lipoprotein cholesterol (LDL-C) target. There are many reasons of this, including physicians’ inertia, including diabetologists and cardiologists, therapy nonadherence, but also underusage and underdosing of lipid lowering drugs due to unsuitable cardiovascular (CV) risk stratification. In the last several years there is a big debate on the risk stratification of DMT2 patients, with the strong indications that all patients with diabetes should be at least at high cardiovascular disease (CVD) risk. Moreover, we have finally lipid lowe…
