Periostin / POSTN: A Cardio-Periodontics Interrelationship

Periodontium consists of soft and hard tissues that are responsible for maintaining the teeth in their functional and anatomical positions throughout life bearing the functional and parafunctional loads at the same time.

PDL also provides a constant source of multipotent mesenchymal stem cells that differentiate into osteoblasts and cementoblasts throughout life
