The Relationship Between Periodontitis and Glycaemic Control in Type 2 Diabetes
Periodontitis is a chronic, inflammatory condition in the tissues surrounding teeth that is stimulated by dental plaque bacteria and results in the destruction of tooth supporting tissues. Type 2 diabetes is associated with an increased prevalence and severity of periodontitis that is related to underlying glycaemic control. It has been suggested that the presence of chronic periodontal inflammation has a converse and negative effect on glycaemic control in diabetes with most evidence emerging from studies of type 2 diabetes. This article reviews the evidence from cohort, prospective and meta-analysis studies that have been conducted to examine the relationship between periodontitis and glycaemic control in type 2 diabetes and suggests underlying pathogenic mechanisms that may explain the relationship between these conditions.
