Objectives: The aim of this study is to analyze the factors that influence adults halitosis. Methods: The subjects of this study were 186 adults aged from 35 to 69, between April 4 and May 30,2012. Data were analyzed with t-test, one-way ANOVA, and binary logistic regression analysis SPSS 19.0. Results: The most influential factor of VSCs was halitosis perceived by others (OR: 5.18; 95% CI: 1.82-14.70), which was followed by oral respiration (OR: 3.65; 95% CI: 1.28-10.41), and O’Leary index (OR:3.40; 95% CI: 1.55-7.46) in the order. The influential factors of ammonia were respiratory disease (OR:30.72; 95% CI: 1.85-51.37), gastrointestinal disease (OR: 12.28; 95% CI: 1.78-44.79), missing tooth (OR: 3.75; 95% CI: 1.57-8.92), periodontal pocket (OR: 2.61; 95% CI: 1.10-6.18), tongue brushing (OR:0.38; 95% CI: 0.15-0.95), and oral prophylaxis (within a year) (OR: 0.31; 95% CI: 0.13-0.75). Conclusions: Halitosis is the result of complex actions among individual characteristics, systematic disease,oral health state, and health behavior.
