Abstract
The use of complementary and alternative medicines (CAM) continues to grow in North America. The most recent National Health Interview Survey found that in 2012, 33.2 percent of respondents reported usage of some form of CAM in the previous 12 months. A survey of adult patients in a U.S. dental school clinic found that 24 percent reported the use of herbal supplements. Dietary supplements and alternative therapies are often used for pain management.
