  • Descrição: The diagnosis of dental caries can lead people to seek additional information on the Internet, through the use of structured queries in search engine tools. This action generates a considerable volume of data, which can be analyzed to provide a better understanding of publics behavior linked to the consumption of oral health information. Nevertheless, health-related information found on the web is being reported to be misleading and of poor quality. This study aimed (1) to assess the volume and profile of web searches on dental caries-related queries performed by Googles users from different countries, and (2) to evaluate the readability and the quality of dental caries-related information from Brazilian websites. The monthly variation of the Search Volume Index (SVI) for dental caries was obtained in Google Trends, for the period between January 2004 and September 2016. To validate the data, the correlation levels between the variation of SVI and the disability-adjusted life-years (DALYs) for permanent teeth were determined. To assess the quality of information, the websites were selected through Google, Bing, Yahoo!, and Baidu. Two independent examiners evaluated the quality of 75 websites using the DISCERN questionnaire and JAMA benchmark criteria. The scores Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level (FKGL), and Férnandez-Huerta Readability Formula (FHRF) were used to assess the readability of the websites. The statistical analysis was performed with P<0.05 considered significant. In all countries, results revealed a trend of an increasing interest of Google users in dental caries issues. The most popular queries were markedly associated with symptoms and dental treatment, with little interest in prevention. The content of websites showed a poor quality by the analysis of both DISCERN (x=35.68, 19-64) and JAMA (x=1.12, 0-3) scores. The websites were classified as high-difficulty reading materials by FRE scores and, in contrast, as simple and accessible by FHRF scores. In conclusion, the Internet data mining could be helpful to establish the dental needs of specific population groups in a near real-time, since the consumption of dental information is increasing in importance and appears to have a direct relation with untreated dental caries. Dental caries-related contents found in Brazilian websites were considered simple, accessible and of poor quality. These findings indicate the need of the development of policies for the production and publication of digital oral health information, encouraging dentists to guide their patients in searching for recommended oral health websites.
