title: Periodontal Health Condition and Associated Factors among University Students, Yemen.
abstract: BACKGROUND
  Studies on oral health status among Yemeni population are scarce.
  
  
  OBJECTIVE
  This study aimed to evaluate the periodontal health among advantaged section of Yemeni society, university students, in health and non-health fields.
  
  
  METHODS
  Periodontal health status of a sample of 360 students from dental, medical and literature faculties (120 each with equal gender distribution) at Sana'a University was evaluated by two calibrated examiners using CPI index. Data regarding tooth-brushing practices and smoking and khat chewing habits were obtained using a structured interview questionnaire.
  
  
  RESULTS
  Only 45 students (12.5%) had healthy periodontium, while 113 (31.4%), 186 (51.7%) and 16 (4.4%) had bleeding, calculus and shallow pocket, respectively, with no significant differences between faculties. Females revealed significantly better periodontal health compared to males, though their bleeding score was higher. Dental and medical students and female students in general were significantly more interested in tooth-brushing and significantly less interested in practicing the deleterious habits such as smoking and khat chewing.
  
  
  CONCLUSIONS
  The overall periodontal health of Sana'a University students is still unsatisfactory even among students in health field. Females and students in health field revealed better periodontal health and oral health practices (tooth-brushing) in comparison to male students and those in non-health field. The negative effects of the highly prevalent smoking and khat chewing habits deserve further reliable researches and proper educational programs at the national level.
