Orthodontic treatment in periodontal patients: A case report with 7 years follow-up [Traitement orthodontique chez les patients atteints de troubles parodontaux : �tude de cas avec sept ans de suivi]
No full textIntroduction: Tooth flaring of the anterior segment is often unesthetic and therefore a primary reason for combined orthodontic and periodontal treatment in adult patients with periodontal disease. Thus, a multidisciplinary approach is frequently chosen for these patients by a qualified dental team. Materials and methods: A clinical case of an adult patient suffering from chronic periodontitis with horizontal bone loss in the anterior segment and consequent flaring of the anterior teeth is described. A combined approach was chosen, initially to improve and stabilize the periodontal situation via multiple scaling and root planning sessions with additional pharmacological therapy and, finally by orthodontic treatment, to resolve the malocclusion. Results: At the end of treatment, bone resorbtion was stabilized, the vertical bone defect was improved and incisor flaring was absent. Follow-up at 7 years post-treatment confirmed the stability of the orthodontic and esthetic results. Conclusions: The correct combination of orthodontic and periodontal treatment may contribute efficaciously to eliminate the effects of chronic periodontitis in adult patients, as well as improving esthetic parameters. � 2011 CEO Published by/�dit�par Elsevier Masson SAS All rights reserved/Tous droits r�serv�s
Il trattamento ortodontico nel paziente affetto da malattia parodontale. Rapporto di un caso con follow up a 7 anni
No full textIntroduzione: lo sventagliamento dei denti nel settore anteriore rappresenta spesso,
nel paziente adulto affetto da parodontopatia, motivo di disagio estetico
e causa prima di richiesta di interveto terapeutico combinato ortodontico-parodontale.
L`approccio multidisciplinare diventa pertanto, in particolar modo per
i pazienti adulti, la scelta di elezione per un team odontoiatrico qualificato.
Materiali e metodi: viene descritto un caso clinico di soggetto adulto affetto
da parodontite cronica con riassorbimento osseo orizzontale dei settori
frontali e conseguente flaring dei denti anteriori. Si decide di procedere
con una terapia combinata che prevede in prima istanza il miglioramento
e la stabilizzazione del quadro parodontale mediante sedute multiple di
Scaling e Root Planning con associata terapia farmacologica di supporto.
In seconda battuta invece si procede alla risoluzione della malocclusione
mediante terapia ortodontica.
Risultati: il paziente a fine cura presenta una stabilizzazione del riassorbimento
osseo e un miglioramento dei difetti ossei verticali con assenza di
flaring incisivo. Il follow up a 7 anni conferma la stabilità del risultato ortodontico
ed estetico raggiunti.
Conclusioni: la corretta combinazione di terapia ortodontica e parodontale
può efficacemente contribuire all’arresto degli effetti della parodontite
cronica dell’adulto, oltre che a un miglioramento dei parametri estetici.Introduction: Tooth flaring in the anterior sector is often unsightly and is therefore
a primary cause of combined orthodontic and periodontal treatment in
adult patients affected by periodontal disease. Thus, a multidisciplinary approach
is frequently chosen for these patients by a qualified odontoiatric team.
Materiale and methods: A clinical case of an adult patient affected by chronic
periodontitis with horizontal bone resorption in the frontal section and consequent
flaring of the anterior teeth is described herein. A combined approach
was chosen, initially to improve and stabilise the periodontal situation via
multiple scaling and root planning sittings with accompanying pharmacological
therapy, and finally to resolve the malocclusion via orthodontic treatment.
Results: At the end of treatment, bone resorption was stabilised, the vertical bone
defect was improved and incisor flaring was absent. A follow-up at seven years
post-treatment confirmed the stability of the orthodontic and aesthetic results.
Conclusion: The correct combination of orthodontic and periodontal treatment
may efficaciously contribute to the arrest of the effects of chronic periodontitis
in adult patients, as well as improving aesthetic parameters
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
Management of Class III Extraction with the Miniscrew-Supported Orthodontic Pseudo-Ankylosis (MSOPA) Using Direct Tads
No full textThe aim of the present study is to represent the orthodontic treatment of a young patient with a skeletal Class III malocclusion(Wits Appraisal -9 mm), in which the extractions of the first lower premolars were performed to obtain a class III camouflage using direct temporary anchorage devices (TADs). The patient reported a history of three years of orthodontic treatment at another clinic and the radiographic evaluation revealed an important impairment of the upper root incisors. A treatment was performed with a fixed appliance in the upper and lower arches using an archwire sequence of 0.16 CuNiTi, 19 x 25 CuNiTi, 19 x 25 SS and was carried out in 18 months. Post-treatment records of our patient show a control of facial esthetics from the frontal and lateral perspectives, with a harmonious soft-tissue profile. A Class I canine was achieved and her overbite and overjet were normalized by retracting the mandibular anterior teeth and carrying out a bodily mesialization of the posterior sector into the extraction space. In conclusion, the "pseudoankylosis system" used in this case allowed the desired result to be achieved with minimal change to the lower incisal inclination and without overloading the anterior upper and lower sectors, thus reducing the risk of further root resorption and patient compliance
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
