All undergraduate medical and dental students irrespective of gender, cast, creed, or socioeconomic status were eligible to partake in the study. The data on demographics including the age, gender, primary way of cleaning teeth, frequency of dental flossing, general oral health habits, assessment of knowledge of interdental cleaning aids etc. were recorded in a structured questionnaire.

Results: The majority of the students acknowledged the importance of the role of students in promoting dental floss use among the community. Years of study in Bachelor of Dental Surgery (BDS) students was significantly associated with cleaning frequency (p < 0.0001) and primary cleaning method (p = 0.001). Interdental cleaning aid awareness, frequency of interdental cleaning, issues from not cleaning the interdental spaces, the role and use of dental floss were all significantly correlated with year of study among BDS students. Use of secondary methods was significantly associated with years of study among Bachelor of Medicine, Bachelor of Surgery (MBBS) students (p < 0.001).
