Low sugar nutrition policies and dental caries

07 / 03 / 17

Researchers evaluated the effect of a healthy food policy on dental caries in a school situated in a socio-economically deprived area of South Auckland, New Zealand compared to eight similar schools with no policy. The policy limited high-sugar foods and drinks. The study was conducted over seven years between 2007 and 2014 and examined dental records for 3813 children aged between 8-11 years. There was a reduction in caries in the intervention school: a mean difference of 0.37 of a caries affected tooth (95% CI;0.09-0.65). Pacific students tended to have more caries than Maori children.
