A Pennsylvania-based study will be featured in the upcoming August issue of the Journal of the American Dental Association (JADA). “Cross-sectional study of association between caries and fluoridated water among third-grade students in Pennsylvania,” authored by Pennsylvania Department of Health Oral Health Program epidemiologist Dr. Jun Yang, also features PCOH Executive Director Helen Hawkey as a co-author. The study found that community water fluoridation was significantly associated with a reduced risk of developing caries among Pennsylvania children.
