Al-Hajri Abdoalbassed Mofudal Alea A Al-Shami Laila Al-Surihy Nusaibe M. Ali Periodontal diseasesare chronic infectious diseases that lead to the inflammation of specialized tissues that surround and support the teeth. Many risk factors and risk indicators, associated with increased risk of periodontal disease, have been identified. Gender, age, education, tooth brushing habit, smoking, khat chewing and shamaa use were associated with periodontal status in Yemen. Accordingly, the aim of our study is to assess the prevalence and related risk factors for periodontal diseases  among Yemeni young dental patients in the faculty of dentistry Sanaa university.735 subjects (both males and females) and systemic free. Clinical examinations were performed including probing pocket depth, plaque index, gingival index and gingival recession. 110 Patients were less than 20 years and  9.1% healthy, 36.4% gingivitis, 22.7% generalized chronic periodontitis (GCP), 4.5% localized aggressive periodontitis (LAP), 27.3% generalized gingivitis with localized chronic periodontitis (LCP) and 0.0% generalized aggressive periodontitis (GAP). 625 Patients were more than 20 years and less than 29 years and 13.6% healthy, 8.7% gingivitis, 29.1% generalized chronic periodontitis (GCP), 2.7% localized aggressive periodontitis (LAP), 45.6% generalized gingivitis with localized chronic periodontitis (LCP) and 0.2% generalized aggressive periodontitis (GAP).Age, gender, education, tooth brushing habit, smoking, khat chewing and shamaa use habit were significantly (P ≤ 0.05) associated with periodontal status. The study confirmed various socio‑demographic risk factors/indictors associated with increased risk of periodontitis among Yemeni young dental patients. 09 01 2017 10.22270/ujpr.v2i5.CS1 http://ujpr.org/index.php/journal/article/view/95 http://ujpr.org/index.php/journal/article/download/95/73 http://ujpr.org/index.php/journal/article/download/95/255 http://ujpr.org/index.php/journal/article/download/95/73 http://ujpr.org/index.php/journal/article/download/95/255
