An important question for oral health education is whether knowledge gained during lay-led workshops is retained and applied in daily practice. This study assessed the knowledge retention and changes in oral health practices several months after oral health education workshops were held for migrant farmworkers by Community Health Workers (CHWs). This project was sponsored by Arcora Foundation.
