Periodontal disease progression is episodic in nature on a tooth site level, but more recently, it has been realized that it is principally patient-based rather than site-based (Zia et al., 2011); the host related risk factors could be the key to better understand disease evolution. The available evidence shows that important risk factors for periodontal disease relate to poor oral hygiene, tobacco use, excessive alcohol consumption, stress, and diabetes mellitus (Laurina et al., 2009; Taylor & Borgnakke, 2008). Degrees of inflammation and fibrosis depend on these risk factors but recently the genetic basis of many aspects of the periodontal host response has been discussed in reference to disorders. | Clive Oxenden Christina Latham-Koenig 100 NEW New ENGLISH FILE Intermediate Student s Book elt englishfile intermediate Clive Oxenden Christina Latham-Koenig New ENGLISH FILE Intermediate Student s Book Pau Sebgson and Clive Oxenden are the original co-authors of English File 1 pub. 1996 and English File 2 pub. 1997 .
