Active implementation strategy of CONSORT adherence by a dental specialty journal improved randomized clinical trial reporting.

OBJECTIVE To describe a novel CONsolidated Standards of Reporting Trials (CONSORT) adherence strategy implemented by the American Journal of Orthodontics and Dentofacial Orthopedics (AJO-DO) and to report its impact on the completeness of reporting of published trials. STUDY DESIGN AND SETTING The AJO-DO CONSORT adherence strategy, initiated in June 2011, involves active assessment of randomized clinical trial (RCT) reporting during the editorial process. The completeness of reporting CONSORT items was compared between trials submitted and published during the implementation period (July 2011 to September 2013) and trials published between August 2007 and July 2009. RESULTS Of the 42 RCTs submitted (July 2011 to September 2013), 23 were considered for publication and assessed for completeness of reporting, seven of which were eventually published. For all published RCTs between 2007 and 2009 (n = 20), completeness of reporting by CONSORT item ranged from 0% to 100% (Median = 40%, interquartile range = 60%). All published trials in 2011-2013, reported 33 of 37 CONSORT (sub) items. Four CONSORT 2010 checklist items remained problematic even after implementation of the adherence strategy: changes to methods (3b), changes to outcomes (6b) after the trial commenced, interim analysis (7b), and trial stopping (14b), which are typically only reported when applicable. CONCLUSION Trials published following implementation of the AJO-DO CONSORT adherence strategy completely reported more CONSORT items than those published or submitted previously.

Exploring the publications in three major orthodontic journals: a comparative analysis of two 5-year periods.

OBJECTIVE To analyze the types of articles and authorship characteristics of three orthodontic journals--American Journal of Orthodontics and Dentofacial Orthopedics (AJODO), The Angle Orthodontist (AO), and European Journal of Orthodontics (EJO)--published between 2008 and 2012 and to assess the differences in content within this period and an earlier period of 1998 to 2002. MATERIALS AND METHODS Each journal's content was accessed through the web edition. From each article, the following parameters were recorded: article type, number of authors, number of affiliations, source of article (referring to the first author's affiliation), and geographic origin. Descriptive statistics were performed and selected parameters were analyzed with the Pearson chi-square or Fisher exact test for independence at the .05 level of significance. RESULTS Review of differences between the two periods showed that the number of publications was almost double. The percentages of multi-authored articles increased. Fewer studies derived from the United States/Canada and European Union countries. Increases for articles from non-European Union countries, Asia, and other countries were found. Characteristics of the second period showed that the EJO and AO published more research articles, whereas the AJODO regularly published case reports and other articles. Approximately 75% of all studies derived from orthodontic departments. CONCLUSIONS The publications from 1998-2002 and 2008-2012 were significantly different both in terms of numbers and characteristics. Within 2008-2012 there were notable differences between the three journals concerning the type and origin of the publications.

Are claims made in orthodontic journal advertisements evidence-supported?

OBJECTIVE To examine the supporting evidence of advertisements published in six leading orthodontic journals. MATERIALS AND METHODS The 2012-2013 printed issues of American Journal of Orthodontics and Dentofacial Orthopedics, Australian Orthodontic Journal, Journal of Orthodontics, European Journal of Orthodontics, Journal of Clinical Orthodontics, and Journal of Orofacial Orthopedics were screened for advertisements implying superior performance compared with competitor products. Advertisements were classified according to type of product, availability, and currency of supporting references. RESULTS A total of 99 unique advertisements claiming clinical benefit or superiority were identified. The overwhelming majority of the identified advertisements promoted appliance products (62.6%), orthodontic materials (14.1%), and dental operatory equipment, including imaging systems (12.1%). Advertisements were found to provide references or not regardless of the product type. Half of the advertisements referred to at least one peer-reviewed publication, whereas unpublished studies were cited by 25% of the advertisements. Most of the referenced articles were published within the past 5 years. CONCLUSIONS The scientific background of advertisements in the orthodontic literature appears limited. While surveillance of journal advertising needs to be regulated, clinicians are urged to critically appraise the claims being made in orthodontic print advertisements by consulting the associated existing evidence.

Tratamento da classe II divisão 1 na dentição mista

Introdução: Os indivíduos portadores da má oclusão de Classe II Divisão 1 possuem diversas etiologias e podem ser encontrados em todas as etnias. As suas características clínicas e radiográficas se agravam com o crescimento e uma vez não tratada, continuam com esta má oclusão por toda sua vida. Para o tratamento ortodôntico na dentição mista recorre-se a dispositivos como aparelhos extra-orais, aparelhos funcionais fixos e removíveis. Objetivo: O objetivo deste trabalho é fazer uma revisão sobre o diagnóstico e tratamento da Classe II Divisão 1 na dentição mista, salientando a importância do tratamento nesta fase. Materiais e Métodos: Para a concretização do presente trabalho foi realizada uma revisão bibliográfica no presente ano, recorrendo-se ao livro “Ortodontia Contemporânea” do autor William Proffit, diversos motores de busca online, nomeadamente, PubMed, Medline, Elsevier e Scholar Google, utilizando como palavras-chave: “Class II Division 1”, “Mixed Dentition”, “Functional Appliance”, “Extra-Oral Appliance”, e revistas de Ortodontia, nomeadamente, American Journal of Orthodontics, Seminars in Orthodontics, The Angle Orthodontist e Dental Press de Ortodontia e Ortopedia Facial. A pesquisa foi realizada sem qualquer tipo de limites temporais, sendo dada uma maior importância a artigos mais recentes. Os artigos foram selecionados segundo o seu rigor científico e interesse para o tema. Numa fase mais avançada de revisão bibliográfica foram usados artigos citados na bibliografia dos artigos selecionados na primeira pesquisa efetuada. Conclusão: A dentição mista é considerada a fase ideal para iniciar o diagnóstico, prevenção, interceção e possível correção dos problemas dentários e/ou esqueléticos associados a uma Classe II Divisão 1. A Ortopedia Funcional dos Maxilares, removível ou fixa, e o uso de aparelhos extra-orais constituem recursos terapêuticos disponíveis para o tratamento desta má oclusão.
