Vitamin D has emerged from obscurity, and its effect on various organ systems throughout the body down to the cellular level is being discovered. What was once thought to be a simple hormone affecting only bone and calcium metabolism has shifted. Vitamin D is now seen as a complex hormone that is involved not only in the calcium homeostasis but also in the integrity of the innate immune system. Reduced serum Vitamin D is linked to inflammatory and long- latency diseases like tuberculosis, arthritis, diabetes ad even gingivitis. Research on the importance of prescribing Vitamin D as a therapeutic and preventive measure in routine practice for many diseases including Gingivitis and periodontal disease is in full swing.
