The Effectiveness of Reinforcement of Oral Hygiene Education Through Video During Fixed Orthodontic Treatment in Adults

Effective oral hygiene education is paramount to ensure lasting good oral hygiene habits in patients receiving fixed orthodontic treatment. Repetition and reinforcement play an important role in the sustainability of oral health behaviour. Video-based oral hygiene education can be provided in chairside, or it can be provided to the participant to watch at home, saving clinicians a lot of time. The study aims to investigate the long-term effects of different methods of video-assisted oral hygiene reinforcement on the oral hygiene of participants receiving fixed orthodontic treatment, as well as the consequences when reinforcement is discontinued. Sixty participants will be randomly allocated to three groups at a 1:1:1 ratio in this three-arm parallel, randomized clinical trial. Sixty participants will be randomly allocated to the control group, study group 1 (onsite video) and study group 2 (remote video). The Orthodontic Plaque Index (OPI) and Full-mouth Bleeding Score (FMBS) will be measured at baseline and every two months for up to 12 months. Following data collection, statistical data analysis will be conducted to compare the outcomes and changes between the three groups.
