Valutazione della guarigione dei siti postestrattivi mediante l’utilizzo di un gel a base di aminoacidie sodio ialuronato. Evaluation of post-extraction sites healing through the application of a gel based on amino acids and sodium hyaluronate
No full textOBJECTIVES. The aim of this study was to compare both oral soft and hard tissue wound healing with and without use of a compound gel containing amino acids and sodium hyaluronate and to evaluate post-operative pain after tooth extraction. MATERIALS AND METHODS. 46 patients were divided into two groups (study group 23 patients and control group 23 patients). In the first group, the gel containing amino acids and sodium hyaluronate (Aminogam®, Errekappa Euroterapici SpA, Milano, Italy) was administered for the whole healing period, while in the second group, no topical substances were applied. Numeric Rating Scale (NRS, 0-10) was used to evaluate pain experienced after surgery. Using millimeter grid paper as a benchmark and a graphic software, Adobe Photoshop®, it was possible to measure the whole surgical wound area, immediately after tooth extraction (Timing 0), at 7 (Timing 1), 30 (Timing 2) and 60 days (Timing 3). RESULTS. The cases treated with the compound gel (study group) showed a higher average percentage of healing than the control group, with regard to both soft and hard tissue. NRS pain scale did not show any significant differences between the two groups. CONCLUSIONS. The use of a gel containing amino acids and sodium hyaluronate promoted a better and faster healing, both of the oral soft tissues, by reducing the surgical wound area in the first week after tooth extraction, and of the hard tissues, through the progressive filling of post-extraction alveoli.
Introduction. Hyaluronic Acid is an extracellular constituent of the connective tissue that belongs to the family of glycosaminoglycans; it promotes and accelerates the healing process of surgical wounds through the stimulation of fibroblasts, collagen synthesis, remodeling of the extracellular matrix and the production of angiogenic cytokines. The aim of this study was to compare both oral soft and hard tissue wound healing with and without use of a compound gel containing aminoacids and sodium hyaluronate (Aminogam®, Errekappa, Italy) and to evaluate the post-operative pain after tooth extraction.

Non-surgical periodontal treatment of peri-implant diseases with the adjunctive use of diode laser: preliminary clinical study
No full textPeri-implant diseases present in two forms: peri-implant mucositis and peri-implantitis. The prevalence of peri-implant complications is significantly rising. The aim of this study was to compare conventional treatment of inflamed peri-implant tissues with conventional treatment together with diode laser application. Twenty-seven patients (age 36 to 67, 15 women and 12 men, 12 smokers and 15 non-smokers) requiring treatment for mucositis or peri-implantitis were taken into account for this preliminary study. Plaque index (PI), pocket depth (PD), and bleeding on probing (BoP) were recorded at baseline evaluation. Patients in control group (CG) received conventional non-surgical periodontal treatment. Patients in test group received conventional non-surgical periodontal treatment together with diode laser application (810 nm, 30 s, 1 W, 50 Hz, ton = 100 ms, toff = 100 ms, energy density = 24.87 J/cm2). Paired t test was used to evaluate the difference in repeated measurements of considered indexes at T0 and T1 (1 year) in both groups. A total of 606 sites were taken into account in the test group (TG) and 144 in the CG. PD mean variation in the TG was 2.66 mm ± 1.07, while mean PD variation in the CG was 0.94 ± 1.13 mm. Paired t testing of the variation in PD in CG and TG revealed a statistically significant difference between the two groups (p < 0.0001). A reduction of pathological sites from 89 % (T0) to 14.35 % (T1) was achieved in the TG, while reduction obtained in the CG was from 75.69 % (T0) to 50 % (T1); BoP scores at time T1 had fallen below 5 % in the TG and decreased to 59.7 %, in the CG. Within the limitations of this study, diode laser seems to be an additional valuable tool for peri-implant disease treatment

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
