Periodontitis is arguably the most prevalent chronic inflammatory disease of humans, affecting more than 45% of US adults aged 30 years and older (1, 2). The defining feature of periodontitis is chronic inflammation of the tooth supporting tissues leading to the progressive irreversible destruction of periodontal ligament and alveolar bone, resulting in the formation of periodontal pockets and eventually tooth loss if untreated. Host susceptibility is clearly of primary importance and tobacco smoking is a strong environmental risk factor (2). This article is protected by copyright. All rights reserved.
