Orthodontic treatment using fixed appliances is a predisposing factor for plaque accumulation because dental cleaning is more difficult. The lack of patient motivation and compliance in maintaining oral hygiene during treatment is also a predisposing factor in plaque build-up. Purpose: This study aimed to determine which motivation methods most influence Oral Hygiene Index scores based on the Plaque Index and the Gingival Index. The study is a randomized, single-blind clinical trial with concealed allocation. The subjects comprised patients treated with fixed orthodontic appliances. The patients' Oral Hygiene Index scores prior to and after being exposed to oral hygiene improvement motivation methods were evaluated. Statistical data processing was performed using univariate analysis, a Kruskal-Wallis test, a Wilcoxon test, and a one-way ANOVA. Three motivation methods were employed-modelling, a printed catalogue and a video. We found a significant difference between the modelling and video groups, followed by the catalogueand video groups. The video motivation method had the most significant effect on decreasing the Oral Hygiene Index score. The most effective method to increase the motivation of patients to maintain dental hygiene and improve plaque and gingival scores was the video method.
