David,
In regard to any realtionship between the ACS and their Relay for Life and the OCF, having the same date is just a coincidence.
I have found that the ACS is not very supportive of OC. In fact one year when I was doing Oral Cancer Screenings at a Relay for Life event, I noticed that as you walked around the track, there were signs with the names of most types of cancers on big signs. Was there one for Oral Cancer? No there wasn't. I asked the local ACS representative why the sixth most common cancer wasn't on a sign and she didn't have an answer for me. Needless to say, I was extremely disappointed, but not surprised.
As far as hygienists doing OC screenings, in our office all 3 of my hygienists are fully trained in doing a comprehensive visual and tactile screenings. Every patient in our practice has this done at their 6 month hygiene visits. New patients have it done at their initial exams by one of the doctors.
