This systematic review looked at eight publications representing five independent prospective cohort studies in children and adolescents and nine Randomized Clinical Trials (RCT) in adults.

Key Findings: The study concluded that the existing evidence on 100% fruit juice intake and caries and tooth erosion is not conclusive. The studies conducted on children and adolescents found no association between 100% fruit juice and tooth decay or dental cavities. These studies reflected normal intakes of juices and dental hygiene practices. While the results of the RCT’s suggested a potential association, this data was primarily conducted using intra-oral devices and conditions that are not reflective of typical juice consumption. More research is necessary to reach definitive conclusions on this subject.
