The collected data were analyzed in SPSS V. 20 by Chi-squared, Analysis of Variance (ANOVA), t-test, and regression analysis.
Results: Mean age of subjects were 23.5 years. 53.6% subject had moderate knowledge about halitosis. The results revealed that the fifth and sixth year students had more information than the third and fourth year students (P<0.0001). Comparing the performance of female and male students indicated a better hygiene status in females. Based on Chi-squared test results, the frequency of using mouthwash was significant in terms of the academic year (P=0.049).
Conclusion: The mean knowledge score of students about halitosis was moderate. knowledge score and oral hygiene status had no significant relationship with marital status. Despite females having a significant better oral hygiene compared to males, the knowledge score about halitosis had no relation with gender.
