Input: Five studies met the criteria for inclusion in the review. Two of these were multi-intervention studies where the dietary intervention was one component of a wider programme of prevention, but where data on dietary behaviour change were reported. One of the single intervention studies was concerned with dental caries prevention. The other two concerned general health outcomes. There were no studies concerned with dietary change aimed at preventing tooth erosion. In four out of the five included studies a significant change in dietary behaviour was found for at least one of the primary outcome variables. There is some evidence that one-to-one dietary interventions in the dental setting can change behaviour, although the evidence is greater for interventions aiming to change fruit/vegetable and alcohol consumption than for those aiming to change dietary sugar consumption. There is a need for more studies, particularly in the dental practice setting, as well as greater methodological rigour in the design, statistical analysis and reporting of such studies.
Output:

We identified five studies. Two of these were concerned with diet advice given concerning general health (one was about alcohol and one was about fruit and vegetable consumption). In both these studies there was a change to healthier behaviour following the advice. We also identified three studies which attempted to change sugar consumption habits in order to reduce dental decay. However, in two out of these three studies there were also other types and forms of advice given at the same time, for example about toothbrushing. It was therefore impossible to say whether changes in diet came about because of the diet advice given or because they were subtly influenced by the other messages. For example: advice on toothbrushing might make patients more aware of their oral health resulting in changes to their diet. Most of the studies concerning sugar consumption are of relatively weak quality. The evidence for dietary advice aiming to change sugar consumption is poor. Further studies in this area should be considered.
