Abstract：
BACKGROUND: Internet has become an indispensable source of health-related information. However, several studies have shown there to be a lack of quality control for webpages related to disability. Specifically, available content concerning Down syndrome (DS) and dentistry is limited and of dubious quality.
OBJECTIVE: The aim of the present study was to assess the quality of online content in Spanish and Portuguese on dental care for individuals with DS.
METHODS: A simultaneous search in Google and Bing using the terms \"Down syndrome\" and \"odontology/dentist/dental treatment\" in Spanish and Portuguese was conducted in seven Ibero-American countries (Argentina, Brazil, Chile, Colombia, Spain, Mexico, and Portugal). The first 100 consecutive pages of results from the three combinations of terms in each of the search engines were accessed and selected by applying conventional exclusion criteria. The selected pages were classified according to their authorship, specificity and dissemination potential. The quality of the online content was assessed using the DISCERN questionnaire and the Questionnaire to Evaluate Health Web Sites According to European Criteria (QEEC). The presence of the Health On Net (HON) and Accredited Medical Website (AMW) seals was also assessed.
RESULTS: The mean DISCERN score was 2.51 ± 0.85 and 2.57 ± 0.86 for the Spanish and Portuguese webpages, respectively. The mean readability score was 3.43 ± 1.26 and 3.25 ± 1.08 for the Spanish and Portuguese webpages, respectively. None of the selected webpages presented the HONcode or AMW trust seals.
CONCLUSIONS: The content available online in Spanish and Portuguese regarding Down syndrome and dentistry is scarce and of highly questionable quality.

摘要：
背景：互联网已成为与健康相关的信息不可或缺的来源。然而,一些研究表明，与残疾相关的网页缺乏质量控制。具体来说,有关唐氏综合症（DS）和牙科的可用内容有限，质量可疑。
目的：本研究的目的是评估关于DS患者牙科护理的西班牙语和葡萄牙语在线内容的质量。
方法：在七个伊比利亚美洲国家（阿根廷，巴西,智利,哥伦比亚,西班牙,墨西哥,和葡萄牙）。通过应用常规排除标准来访问和选择来自每个搜索引擎中的三个术语组合的结果的前100个连续页面。选定的页面根据其作者身份进行分类，特异性和传播潜力。使用DISCERN问卷和根据欧洲标准（QEEC）评估健康网站的问卷评估在线内容的质量。还评估了健康在线（HON）和认可医疗网站（AMW）密封的存在。
结果：西班牙语和葡萄牙语网页的平均DISCERN评分为2.51±0.85和2.57±0.86，分别。西班牙语和葡萄牙语网页的平均可读性得分分别为3.43±1.26和3.25±1.08,分别。所选网页均未显示HONcode或AMW信任印章。
结论：关于唐氏综合症和牙科的西班牙语和葡萄牙语在线提供的内容很少，质量非常可疑。
