This study aimed to assess the quality of the information available on the Web on gum disease.
The term "gum disease" was searched in Google and in MedlinePlus. The first 200 websites were analysed by the Journal of the American Medical Association (JAMA) criteria and the Health On the Net Foundation (HONCode) certification, instruments for assessing quality of health information. Data were analysed the Mann-Whitney test or Kruskal-Wallis test, followed by the Dunn's test, using the GraphPad Prism Software version 6.
MedlinePlus presented a significantly higher JAMA score than Google. Google's first 10 results had a higher JAMA score than the remaining websites. Journalism and health portals the most reliable affiliations, while commercial and dental practices had low JAMA scores. JAMA score was significantly higher in websites with the HONCode certification compared to the ones without it.
Currently, there are concerns regarding patients' use of the Internet for accessing health information. However, the conclusion we can make is that Google seems to favour websites with high quality information, at least in terms of JAMA score or HONCode accreditation. The JAMA score of dental practices' websites could be improved by providing basic information such as authorship and date.
本研究旨在评估网络上有关牙龈疾病信息的质量。
在 Google 和 MedlinePlus 中搜索“牙龈疾病”一词。使用美国医学会（JAMA）标准和健康网络基金会（HONCode）认证这两种工具，对前 200 个网站进行分析，这两种工具是评估健康信息质量的工具。使用 GraphPad Prism 软件版本 6 分析数据，采用 Mann-Whitney 检验或 Kruskal-Wallis 检验，然后采用 Dunn's 检验。
MedlinePlus 的 JAMA 评分明显高于 Google。Google 的前 10 个结果的 JAMA 评分高于其余网站。新闻和健康门户网站是最可靠的关联网站，而商业和牙科诊所的 JAMA 评分较低。与没有 HONCode 认证的网站相比，具有 HONCode 认证的网站的 JAMA 评分明显更高。
目前，人们对患者使用互联网获取健康信息的情况存在担忧。然而，我们可以得出的结论是，谷歌似乎更倾向于高质量信息的网站，至少在 JAMA 评分或 HONCode 认证方面是如此。通过提供作者和日期等基本信息，可以提高牙科诊所网站的 JAMA 评分。
