First-Year Dental Students

Participants in this cohort are undergraduate dental students in their first year of dental education at Recep Tayyip Erdoğan University Faculty of Dentistry. This cohort represents students at the beginning of their dental education. Participants will undergo halitosis assessment using subjective and objective evaluation methods, including halitosis questionnaire, organoleptic assessment, portable digital halitometer measurement of volatile sulfur compounds (VSCs), tongue coating index evaluation, and DMFT index recording. Perceived stress levels will also be evaluated using the Perceived Stress Scale. No intervention will be applied.

Fifth-Year Dental Students
