Association of dental caries with use of internet and social media among 12 and 15-year-olds.

The association between use of internet and social media, and dental caries could be mediated by health behaviours. Younger adults and children may be using the Internet and social media seeking information on dental caries, but longer online hours may also increase the caries risk. Internet-based health interventions should be supported by preventive strategies to promote effective and positive internet use.
