Aim: This study aimed to assess the quality of the information available on the Web on gum disease.

Methods: 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 was analysed through the Mann-Whitney test or KruskalWallis test, followed by the Dunn’s test, using the GraphPad Prism Software version 6.

Results: MedlinePlus presented a significantly higher JAMA score than Google. Google’s first ten results had a higher JAMA score than the remaining websites. Journalism and health portals are 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.

Conclusion: There are current 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.
