Water fluoridation information found on the World Wide Web.

OBJECTIVE There is much controversy over the fluoridation of community water supplies. This study surveyed the informational content of internet sites on the World Wide Web (WWW) regarding water fluoridation. METHODS One hundred websites were identified and 59 were evaluated with a 6 point scoring system using predetermined criteria. RESULTS Of these 59 sites, 54% recommend water fluoridation as compared to 31% that oppose it. CONCLUSIONS The informational content of WWW sites may range from factual, to unsubstantiated opinions, to frank fraud. However, this information is presented to the public indiscriminately. The informational content of the WWW contains varied views and recommendations for community water supply fluoridation. Public health officials and practicing physicians should be aware that the internet WWW may influence public opinion.
