To examine the supporting evidence of advertisements published in six leading orthodontic journals.
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.
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 Half of the advertisements referred to at least one peer-reviewed publication, whereas unpublished studies were cited by 25% of the advertisements.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.
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.
研究六种主要正畸期刊上发表的广告的支持证据。
对《美国正畸与牙颌面正畸杂志》《澳大利亚正畸杂志》《正畸杂志》《欧洲正畸杂志》《临床正畸杂志》和《口颌面正畸杂志》2012 - 2013年的印刷版进行筛选，查找暗示比竞争产品性能更优的广告。广告根据产品类型、可得性和支持参考文献的时效性进行分类。
共识别出99则声称具有临床益处或优势的独特广告。绝大多数已识别的广告宣传矫治器产品（62.6%）、正畸材料（14.1%）以及牙科诊疗设备，包括成像系统（12.1%）。发现广告是否提供参考文献与产品类型无关。一半的广告提及至少一篇经同行评审的出版物，而25%的广告引用了未发表的研究。大多数被引用的文章是在过去5年内发表的。
正畸文献中广告的科学背景似乎有限。虽然期刊广告监管需要规范，但敦促临床医生通过查阅相关现有证据，审慎评估正畸印刷广告中的宣称内容。
