| Outline of Final Research Achievements |
Diet is a major modifiable contributing factor in the etiology of dental caries and erosive tooth wear that are prevalent. The dietary advices from oral health perspective need to involve prevention of both. The aim of this study was to investigate the impact of dietary intake patterns on plaque acidogenicity, and occurrence of dental caries and erosive tooth wear among Japanese children. The results suggest that frequency of between-meal sugar consumption might play a greater role for caries development and raising plaque acidogenicity in this population. Several kinds of food or drink items were found to be significantly associated with dental caries and/or erosive tooth wear. We conclude that treatment for, and prevention of, dental caries and erosive tooth wear should include more attention to such dietary contribution, and suppression of plaque acidogenicity.
