This Guide For Trainers was developed for the Healthy Teeth Healthy Communities (HTHC) project of the Office of Dental Health (ODH) of Alameda County Public Health Department (ACPHD). HTHC was a Local Dental Pilot Program (LDPP) of the Dental Transformation Initiative (DTI), funded by the California Department of Health Care Services (DHCS). HTHC project period was from April 2017 to December 2020. A dental care coordination curriculum was created and offered to community health workers called the Community Dental Care Coordinators (CDCCs) during the HTHC project period. This Guide is based on the lessons learned from the training given in 2017 and the experiences from the actual dental care coordination field-work done by the CDCCs during 2018-2020.
