Effect of Dental Education Duration on Halitosis and Associated Factors

Официальное название

Assessment of the Relationship Between Duration of Dental Education and Halitosis, Oral Hygiene Behaviors, and Associated Factors Among Dental Students

Обзор

The study population will consist of undergraduate dental students enrolled at Recep Tayyip Erdoğan University Faculty of Dentistry. A total of 100 students, including 50 first-year and 50 fifth-year dental students, will be included. Eligible participants will be healthy students who meet the study criteria and provide written informed consent. Participants will undergo subjective and objective halitosis assessments, including questionnaires, organoleptic evaluation, volatile sulfur compound measurements, tongue coating assessment, and DMFT index recording.

Подробное описание

Halitosis, also known as oral malodor, is a multifactorial condition primarily associated with volatile sulfur compounds produced by bacterial metabolism in the oral cavity. Although previous studies have investigated factors related to halitosis, limited information is available regarding the influence of dental education duration on objective halitosis measurements and associated behavioral and psychological factors.

This study will compare first-year and fifth-year dental students to evaluate whether the duration of dental education is associated with differences in halitosis levels. Objective measurements, including organoleptic assessment and portable digital halitometer measurements of volatile sulfur compounds, will be combined with subjective assessments of halitosis perception, oral hygiene habits, perceived stress levels, tongue coating index, and DMFT index.

The findings of this study may contribute to understanding the relationship between dental education, oral health awareness, lifestyle behaviors, psychological factors, and halitosis among future dental professionals.
