The Oral Health Knowledge and Status among a Group of Medical Institute Students in Sulaimani City/Iraq
Full text linkObjective: This study aims to assess oral health knowledge, practices, and periodontal parameters among medical institute students in Sulaimani City, Iraq. Methods: A descriptive cross-sectional study was conducted with the help of a self-administered questionnaire and clinical examination of periodontal parameters (plaque index (PI), Bleeding Index (BI) and Clinical Attachment Level (CAL)) among (200) medical institute students at Sulaimani City/Iraq. The questionnaire inquired about demographic details of students, which included students’ age and gender, and assessed the students’ knowledge about their oral health care, while the second part was based on oral health practices, with clinical examination conducted for each student by a periodontics specialist. Data obtained were analyzed using the Statistical Package for Social Sciences (SPSS) version 20 (IBM Corporation). Results: The results showed that PI and BI with irregular brushing (1.2 (1.18), 12 (17.75), and 27.5 %), respectively, were more prevalent among male students than females, while all students more adopted the combined brushing technique (65.5%). Conclusions: Male students are less aware of their oral hygiene behavior and practice. Oral hygiene awareness programs to help and educate students on the need to adopt the correct techniques for tooth brushing and flossing are required to promote effective dental plaque control in an effort to maintain proper dental hygiene and avoid periodontal diseases
Gingival Pigmentation Pattern in Correlation to Skin Color in a Group of Kurdish People in Sulaimani City
Full text linkBackground: Melanin pigmentation of the gingiva appears in all ethnicities. Excessive pigmentation is an esthetic concern that has increased awareness about depigmentation procedures. This epidemiological study aims to find the correlation between skin color and gingival pigmentation in Sulaimani Governorate, Kurdistan/Iraq.
Subjects and Methods: A total of 820 apparently healthy and non-smokers, including 338 males and 482 females with healthy gingiva, aged between (18-40 years old) were enrolled in this study. Clinical examination on the participants’ gingivae was performed to assess color, and the distribution of pigmentations. Afterward the of participants skin color were visually examined and divided into six groups according to the Fitzpatrick scale.
Results: Skin color of (53%) of our participants was medium to light brown. Most of the pigmentations were observed in the attached gingiva and interdental papilla (26.83%) and least being in the marginal gingiva and interdental papilla (9.27%). A statistically significant correlation was found between the participants’ skin color, and the intensity of their gingival pigmentations
Conclusion: Darker-skinned subjects haveeavieringival pigmentation compared toair-skinned people in Sulaimani Governorate, Kurdistan/ Iraq. The intensity of gingival pigmentation increases with age with the highest rate of gingival pigmentation was in the upper and lower second premolar to premolar area
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
Effect of Psychological Stress on Salivary Cortisol and Periodontitis
Full text linkObjective: The progression of periodontitis, induced by polymicrobial dysbiosis, can be modified by systemic or environmental factorssuch as stress or anxiety that affect host response. This study evaluates the potential associations between psychosocial stress, salivarycortisol and periodontitis.Methods: In this cross-sectional study, 80 adult participants (41 males and 39 females) aged 20-45 years were included. Participantscompleted a stress self-assessment using a PSS scale questionnaire. Samples of saliva were collected for testing cortisol levels byELISA. The participants were then divided into four groups established on periodontal parameters (plaque index (PI), bleeding onprobing (BOP), probing pocket depth, and clinical attachment level), and stress levels: Group 1 (healthy periodontium without stress),Group 2 (periodontitis without stress), Group 3 (healthy periodontium with stress), and Group 4 (periodontitis with stress).Results: Statistically significant differences were observed between the values detected in the four experimental groups for PI, BI, PD,and CAL (p≤0.05). The highest means of cortisol level were revealed in the stressed healthy group and stressed with periodontitisgroup, at 39.7 and 40.5, respectively. Hence there were statistically significant differences overall across the four groups (p≤0.05).Conclusions: This study demonstrates that psychosocial stress is a risk factor for periodontal diseases, and in cortisol, as one of theelements that enhance periodontal damage, increases were recorded for all four clinical parameters, BI, PI, PD, CAL, which are usedas diagnostic tools for periodontitis
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
