Barriers for dental treatment of primary teeth in East and West Germany
No full textBackground.In many countries, restorative treatmentin primary teeth is suboptimal.Aim.Thus, this study tried to detect barriers fordentists to restore primary teeth in kindergartenchildren (3–6 years).Design.For a representative survey, 320 dentists(184 West, 136 East Germany) were randomlyselected from the dental associations’ registersand asked to answer a questionnaire on theirprofile, their view of the National Health System,and possible barriers for restoring primaryteeth.Results.The analysis (response rate 57.7%)showed that the parents were no barrier and thedentists felt the need of restoring primary teeth.In addition to the children’s anxiety, the inadequatereimbursement for fillings were perceived as clearbarrier. The comparison of West and East Germandentists detected statistically significantly higherbarriers in West Germany, where – in contrast tothe German Democratic Republic – no structuredtraining in paediatric dentistry was compulsorybefore unification. Only 35% of the East Germandentists rated restorative treatment in 3- to 6-year-oldsas stressful in contrast to 65% in West Germany,where especially male dentists found no time totreat children.Conclusion.This study reveals that dentists can alsobe a considerable barrier to restorative treatment insmall children, especially without adequate trainingin dental schools
How to intervene in the caries process: proximal caries in adolescents and adults—a systematic review and meta-analysis
No full textObjectives!#!For an ORCA/EFCD consensus, this systematic review assessed the question 'How to intervene in the caries process in proximal caries in adolescents and adults'.!##!Material and methods!#!Separating between the management of initial and cavitated proximal caries lesions, Medline via PubMed was searched regarding non-operative/non-invasive, minimally/micro-invasive and restorative treatment. First priority was systematic reviews or randomized controlled trials (RCTs), otherwise cohort studies. After extraction of data, the potential risk of bias was estimated depending on the study type, and the emerging evidence for conclusions was graded.!##!Results!#!Regarding non-invasive/non-operative care (NOC), no systematic reviews or RCTs were found. In cohort studies (n = 12) with a low level of evidence, NOC like biofilm management and fluoride was associated with a low proportion and slow speed of progression of initial proximal lesions. Minimally/micro-invasive (MI) treatments such as proximal sealants or resin infiltration (four systematic reviews/meta-analyses) were effective compared with a non-invasive/placebo control at a moderate level of evidence. Data on restorative treatment came with low evidence (5 systematic reviews, 13 RCTs); with the limitation of no direct comparative studies, sample size-weighted mean annual failure rates of class II restorations varied between 1.2 (bulk-fill composite) and 3.8% (ceramic). Based on one RCT, class II composite restorations may show a higher risk of failure compared with amalgam.!##!Conclusions!#!Proximal caries lesions can be managed successfully with non-operative, micro-invasive and restorative treatment according to lesion stage and caries activity.!##!Clinical relevance!#!Proximal caries treatment options like non-operative, micro-invasive and restorative care should be considered individually

Silver-Mediated Direct sp(3) C-H Bond Functionalization
No full textDirect sp(3) C-H bond functionalization is an efficient, straightforward, and powerful method to construct new C-X (X = C, N, F, S) bonds from nonfunctionalized aliphatic motif of organic molecules, which has been used in late-stage modification of complex molecules. In this chapter, the recent developments of silver-mediated direct sp(3) C-H functionalizations are reviewed, categorized by C-C bond formation (C-H insertion), C-N bond formation (intramolecular and intermolecular amination/amidation), C-F bond formation, and C-S bond formation.SCI(E)[email protected]

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
