No full textOBJECTIVES. Scleroderma is an autoimmune disease causing vascular alterations, fibrosis and atrophy that involve oral tissues. The aim of this study is to resume the available literature and to focus on the most important problems for the dentist, in order to plan an appropriate management of patients with scleroderma. MATERIALS AND METHODS. PubMed database was searched using the following keywords: scleroderma, microstomia, oral health. RESULTS AND CONCLUSIONS. Oral manifestations of scleroderma include fibrosis and loss of elasticity of perioral tissues, with consequent reduction of mouth opening, and soft tissue intraoral fibrotic changes. Oral hygiene in these patients is usually impaired due to reduced mouth opening and poor manual dexterity. It is essential that the dentist is aware of the most important signs to plan a customized therapy
Oral health conditions in a group of down patients
No full textObjective: The aim of this study has been to evaluate the oral health status in patients suffering from Down's Syndrome living both within their families and institutionalized structures. Methods: Among the recruited patients, in total 160 subjects aged between 20 and 24, 83 were taking part to the Olympic Games (Caorle, June 2002). DMFT and CPITN have been used as epidemiologic parameters in conformity with the World Health Organization standards. Results: The index of caries experience has resulted to be DMFT=6,67 (D=3,00; M=0,99; F=2,68). The periodontal conditions examination has evidenced the following CPTIN values: healthy=26,69%, gingival bleeding=1,50%, calculus=41,35%, 4-5mm periodontal pockets=13,90%, deep periodontal pockets=3,00%, excluded patients for edentulism=13,56%. Sextants: healthy=3.01, gingival bleeding=0,13, calculus=1,58, 4-5mm pockets=0,28, deep pockets=0,03, excluded sextants for edentulism=0,97. A presence of dental agenesia has been diagnosed with an incidence of 15,90% (incisors=60%, canines=12%, premolars=20%, molars=8%). The presence of soft oral pathologies has been observed, most of them has resulted to be fissured tongue and macroglossia corresponding to a respectively incidence of 39,70% and 19,20%. Discussion: Macroglossia has been considered as a preventive factor against the calculus deposits located on the lingual surface of the lower dentition. Data relative to epidemiologic indexes DMFT and CPITN of the patients suffering from Down's Syndrome have been compared with the same indexes of a group of military recruits. This comparison shows that there are differences in the values of DMFT (DMFT Down subjects=6,67; military recruits=5,23) and CPITN. These disparities are caused by a low oral hygiene level in the Down patients. Conclusions: It has resulted essential for Down Patients to receive regular odontoiatric cares and suitable instructions in order to maintain an adequate level of oral hygiene since a childish age. It would be appropriate to combine it a correct fluorine prophylaxis, so that to avoid the beginning of dental caries

Short (8-mm) dental implants in the rehabilitation of partial and complete edentulism : a 3- to 14-year longitudinal study
No full textPURPOSE: This study aimed to evaluate the clinical effectiveness of different implant sizes (8- and 10-mm lengths with 3.75-, 4.1-, and 4.8-mm diameters) in diverse host bone sites in a selected sample of partially and completely edentulous patients. MATERIALS AND METHODS: Over a 14-year period, 129 patients (68 women and 61 men) were consecutively treated with a fixed prosthesis (single or multiunit, screw or cement retained) supported by 265 different-sized implants (154 standard 10-mm; 111 shorter 8-mm). Two types of implants were used (141 titanium plasma-sprayed and 124 Sand-blasted, large-grit, acid-etched). RESULTS: Dropouts were recorded for 23 patients with 23 prostheses supported by 42 implants. In the remaining 106 patients (223 implants), 8 implants failed (4 standard and 4 shorter), in type 3 or 4 bone. Mean marginal bone loss and gingival crevice probing depth associated with either implant length were statistically comparable (P> .05). The 14-year cumulative survival rates for all short and standard implants were 97.9% and 97.1%, respectively. Survival rates were 92.3% and 95.9% for titanium plasma-sprayed short and standard implants, respectively, and 100% and 98.5% for the Sand-blasted, large-grit, acid-etched short and standard implants, respectively. Six of the 8 lost implants required implant replacement after the host sites' healing period. The remaining 2 lost implants were managed by converting the distal unit of the fixed partial prosthesis to a cantilever. CONCLUSION: Within the limits of the study design and observation period, a mix of implant sizes did not appear to compromise the effectiveness of implant therapy in this particular population group
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
