This webpage is devoted to providing dental teams and our medical and community partners with information about fluoride varnish, including literature that provides evidence of its effectiveness. There is also a link to the online course, which provides instruction in the application of fluoride varnish, available to all involved in the IHS ECC Collaborative.
