Management of a Facial Talon Cusp on a Maxillary Permanent Central Incisor: A Case Report and Review of the Literature
No full textBackgroundA talon cusp is a morphologically well-delineated accessory cusp. This case report discusses the unusual appearance of a talon cusp on the facial surface of the maxillary right permanent central incisor, which was conservatively treated and followed up for a period of 1 year

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
The comparison of different coronal restorations of endodontically treated posterior teeth on the patients' quality of life and satisfaction
No full textBACKGROUND AND AIM: Everyday lives of individuals can be affected by dental treatments. The aim of this study was to evaluate the impacts of coronal restorations of endodontically treated posterior teeth (ETPT) on the patient's satisfaction and quality of life (QoL). METHODS: This cross-sectional clinical study was conducted at School of Dentistry, Istanbul Okan University, Istanbul, Turkey, using the semantic differential scale, Oral Health Impact Profile-14 (OHIP-14), and clinical assessments. Electronic charts and files of patients who received endodontic treatment and coronal restoration from June 2018 to January 2019 were reviewed. The patients included in the study had been treated by the same endodontist and restorative dental specialist. The coronal restoration of the ETPT had to be either direct composite restoration (DCR) or indirect ceramic restoration (ICR). 123 patients were deemed fit for this study. A rendezvous was created for the patients who agreed to participate in the study (n = 115) and those who came to the appointment were checked for the inclusion criteria. After clinical examinations, 68 patients filled in the questionnaires. Demographic information, the semantic differential scale, and the OHIP-14 scores-provided data were analyzed by Mann-Whitney U test, independent samples t-test, and the chi-square test. Statistical significance level was considered at P 0.05. RESULTS: 68 patients (n = 34 in each group) participated in the study. DCR and ICR groups had similar mean OHIP-14 scores (5.03 +/- 3.36 and 5.15 +/- 6.17, respectively) and general satisfaction scores (9.76 +/- 0.43 and 9.88 +/- 0.33, respectively) (P 0.05). There was no statistically significant difference between the satisfaction values of the two groups regarding cost, time involved, pain, aesthetics, chewing ability, pleasantness, and general satisfaction (P > 0.05). CONCLUSION: According to the results of the present study, both treatment options have created similar satisfaction for patients and offered high QoL
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
