Multifactorial statistical analysis toward evaluation of MBL, PES and PI of a novel nonsubmerged implant to restore a single tooth: A 1-year prospective cohort study
Full text linkO b j e c t i v e
The objective of this study was to evaluate radiographic, clinical and
esthetic parameters of a new type of nonsubmerged 2-piece implant
placed in patients in need of single-tooth replacement.
M a t e r i a l s a n d m e t h o d s
Fifty-four consecutive patients requiring single-tooth replacement
received 62 2-piece nonsubmerged flapless implants characterized by
an innovative hyperbolic neck. The implant placement timing was as
follows: 15 immediately post-extraction (immediate), 18 after 8–12
weeks (early) and 29 after 10–12 months (delayed). Customized abutments
with an abutment–implant connection approximately 1–2 mm
above the soft-tissue level were positioned after 3 months, loaded with
provisional crowns and 20 days later with definitive crowns.
Gingival biotype (thin or thick) was investigated in all patients. Periimplant
marginal bone level (MBL; mm) was measured single-blinded on
periapical radiographs at 1, 3, 6 and 12 months (T1, T3, T6, T12). Papilla index
(PI), plaque score and bleeding on probing (BoP) were evaluated as clinical
parameters of soft tissue. Pink Esthetic Score (PES) was calculated as
the esthetic parameter.
R e s u l t s
The survival rate was 100%. The dropout rate was 1.85%. The mean MBL
was - 0.01 ± 0.26 at T1, - 0.17 ± 0.38 at T3, - 0.28 ± 0.32 at T6 and
- 0.37 ± 0.41 at T12. The PES (0–14) was 7.30 ± 2.80 at T0 (preoperatively),
11.06 ± 0.97 at T6 and 11.95 ± 1.04 at T12.
At (T12), delayed implants showed a greater (P < 0.05) bone loss compared
with early and immediate implants. Implants placed in thin biotype tissue
showed the greatest bone loss at 12 months with a significant (P < 0.01)
difference with respect to that at (T6). PES and PI increased from T0 to T12.
C o n c l u s i o n
These implants allow preservation of a good MBL and offer a new
approach to soft- and hard-tissue management, allowing a reduced
healing time with minimally invasive surgery, no additional re-entry and
fewer complications

In questo numero intervistiamo due figure chiave dell’evento bolognese: il professor Lucio Montebugnoli, presidente del comitato organizzatore del Congresso, e il professor Lorenzo Lo Muzio, presidente nazionale SIPMO e presidente del congresso
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
