Alteration of subgingival microbiome in patients with type 2 diabetes induced by diabetes treatment

Journal of Diabetes Investigation, EarlyView.
ABSTRACT Aims/Introduction Diabetes and periodontal disease, a bacterial infection involving the oral microbiome, have a bidirectional relationship. However, the relationship between poor glycemic control and the oral microbiome remains unclear. The aim of this study was to assess the direct effect of intensive glycemic control on the oral microbiome ...
