Recommended Dental Hygiene Websites

It can be difficult to find websites that have reliable information. Your instructors may restrict the types of websites used for a project because it can be difficult to find the author, if the site has been reviewed, or even when it was published. Anyone can add anything to the internet, so it is best to proceed with caution, especially when researching health-related topics. Some types of websites that you can trust to provide authoritative information include:

Professional organization websites

Professional organizations can be extremely valuable, both during your time as a student and later as a professional yourself.  These sites provide information and resources on current issues and developments of significance to the dental hygiene profession.  Some, like the American Dental Hygienists Association, also offer free online access to publications and research papers contributed by association members. 

American Dental Hygienists Association -- be sure to look at Access, the official publication of the ADHA (this journal is included in the CINAHL database

Illinois Dental Hygienists Association

International Federation of Dental Hygienists 

American Dental Association

Government websites

Websites for governmental organizations are great sources for reliable, mostly consumer-friendly information, though they do often offer more in-depth research, as well.  Indeed, these sites strive to make the massive amounts of government-funded health research accessible and understandable to the public.
