Objective: The aim of the research was to determine which method of motivating patients to maintain oral hygiene during orthodontic therapy is the most successful. Study plan: Cross-sectional survey of the specialist practice of dental medicine for orthodontics at the Osijek-Baranja County Health Center in Osijek. Participants and Methodology: 37 patients of the Osijek-Baranja County Health Center in a specialist orthodontic practice participated in the research. A survey questionnaire was created on the subjects' oral hygiene habits and two examinations were conducted where the plaque and bleeding index were recorded. The first inspection was carried out during the installation of the fixed device and the second inspection during the first control. Results: 37 respondents participated in the research. A questionnaire was conducted and, of the total number of respondents, 14 of them (38%) have received oral instructions, 11 respondents (30%) have received video instructions and 12 respondents (32%) have received written instructions on maintaining oral hygiene during orthodontic therapy. The results based on statistical processing indicate that most of the respondents were motivated to improve their oral hygiene after they were given the instructions on oral hygiene, but that the video instructions had the greatest impact due to the visualization of the process. Conclusion: Oral hygiene is extremely important for the general health and the health of the teeth and periodental tissue of an individual, especially during orthodontic therapy, therefore its maintenance must be adequately carried out. The conducted research points to the conclusion that education and communication with patients is extremely important and that the visualization (in this case video instructions) of maintaining hygiene helps in its progress.
