Objective: To assess the attitudes and habits of orthodontic patients regarding oral health, and to determine the clinical status of the oral cavity of orthodontic patients through a clinical examination. Materials and methods: The research was based on an anonymous and voluntary survey and was conducted among patients of the Orthodontics Outpatient Clinic of the University Hospital of Split. A total of 50 respondents, aged between 11 and 18, participated in the research. A clinical examination of the oral cavity was also performed, and the DMFT index was determined. The statistical tools of the Microsoft Office Excel 2016 program and the Social Science Statistics online calculator were used for statistical data processing. Results: The greatest percentage (82%) of orthodontic patients claim that they brush their teeth at least twice a day. All of them use a toothbrush, and 98% also use toothpaste. Dental floss is the most commonly used dental cleaning aid (40%). Even 72% of respondents do not know enough about the composition of the toothpaste they use. 72% of them have visited their general dentist in the last six months, and the majority (62%) stated that the reason for the visit was a regular examination / preventive procedure. The most common complaint regarding the oral cavity was dry mouth, which was experienced by 40% of respondents. 38% of respondents consumed fresh fruit every day. Lemonade, Coca-Cola®, or some other carbonated drinks are consumed by 62% of respondents every week. For almost half (48%) of the respondents, the nearest dentist is less than 2 kilometres away. The average DMFT index is 3.48. Conclusion: The respondents take good care of their oral health; they brush their teeth at least twice a day, and they visit their dentist regularly to have a preventive examination where they learn information about oral health, but they do not have enough knowledge about toothpaste. A good indicator is the average DMFT index (3.48), which is lower than the average DMFT index (4.18) in our country.
