The Internet Dental Forum is one of the oldest online forums for dentistry, existing since 1994. It consists of multiple dental-related discussion forums. The most popular with dental professionals is the main clinical list simply called the Internet Dental Forum, or IDF for short. The purpose of the IDF is:

"to promote conversation regarding dentistry among
those directly involved with patient care, be it a dentist, dental hygienist, dental assistant, dental lab technician, dental student, etc."

What makes the IDF different from other dental discussions list is strict adherence to a no advertising policy.

Discussions are specifically for those who desire to learn and to share their knowledge and experiences.
