No definitive evidence has been found that community water fluoridation has negative health effects, according to a review by the Health Research Board (HRB).

The HRB has published an in-depth evidence review of existing research in relation to the health effects of community water fluoridation.

Dr Graham Love, Chief Executive at the Health Research Board, said: "Having examined the research available, the HRB has found no definitive evidence that community water fluoridation is associated with positive or negative systemic health effects.

"Given the lack of peer-reviewed research and the inappropriate design of many studies to detect a causal relationship, further research would be required to provide definitive proof."
