Cellular inflammation from immune cells appears to be the common biological denominator that is the link between type 2 diabetes and periodontal complications.

Abstract
Type 2 diabetes and periodontal disease are separate inflammatory diseases that augment each other. A complication such as type 2 diabetes makes people more likely to have problems with oral health and has been shown to promoteperiodontal disease. In turn, periodontal disease appears to exacerbate type 2 diabetes. Cellular inflammation from immune cells appears to be the common biological denominator that is the link between type 2 diabetes and periodontal complications.

Introduction
Inflammatory diseases share a common biological denominator which is the ability to produce pro-inflammatory cytokines that play an important role in physiologic regulation of many biological activities. However, inflammatory diseases sometimes produce cytokines at levels that have pathological consequences.
