| Outline of Final Research Achievements |
In this study, root caries-induced model was constructed in vitro using the oral streptococci or Actinomyces species. With respect to the change of bacterial species and culture conditions, the penetration depth and dentinal tubules diameter into the dentinal tubules in the lesion of root surface caries were analyzed. As the results, it was indicated that the number of colonization and dentin invasion depended on bacterial species. These findings suggest that bacterial infection of root dentin caries are heavily involved in dental caries pathology.
