1、Centers for Disease Control and Prevention Water Fluoridation Reporting System Overview,Water Fluoridation Reporting System (WFRS) is a web-based database for managing water fluoridation in a state CDC hosts a “data shell” and states enter and maintain jurisdiction data over the internet Jointly dev
2、eloped with the Association of State and Territorial Dental Directors Access is restricted to approved state officials, and determined by State Dental Director,Functions of WFRS,Verify/Modify information about individual water systems Relationships between systems Enter monthly fluoride reading data
