The purposes of this study were to determine the sugar-sweetened beverages (SSBs) consumption and knowledge of sugars among Thai dental students and explored the relationship between students’ knowledge, SSBs consumption, and BMI. The sixth-year dental students from 10 universities in Thailand answered the online beverage intake questionnaire (BEVQ). Association between gender, region, BMI, knowledge, and SSBs consumption was analyzed by using the Chi-square test. Among 327 dental students, 67.3% had a moderate level of knowledge of sugar consumption. The topics that students knew the least were the sugar intake recommended by WHO and the amount of sugar in various foods. The average sugar consumption from SSBs was 42.03 grams per day among dental students. The SSBs that students drank mostly were freshly prepared beverages (44.09%), soft drink (13.31%), and sweeten tea (8.5%).  Students outside Bangkok were 1.8 times more likely to consume SSBs, compared to those in Bangkok (95% CI: 1.2-2.8, p = 0.01). The SSBs consumption was significantly associated with the region of dental schools, but not associated with gender, knowledge, and BMI.  In summary, most dental students had moderate knowledge about sugar consumption and consumed sugar more than WHO recommendation. The knowledge and practice in reducing sugar consumption should be more emphasized in the dental curriculum.  Dental organization should promote nutrition education, health policy and environment to decrease sugar consumption among dental students.
