Efficacy of oral health education intervention to improve oral hygiene of children with hearing impairment

1. Delivery of Oral Health Education via Video The intervention will be conducted in a designated room that can accommodate up to 25 students at a time. Students will be seated in chairs arranged to ensure a clear view of a large-screen TV. The TV will be set up in advance, and the video will be thoroughly tested beforehand to ensure smooth playback. The five-minute video addressed the benefits of fluoride, correct tooth-brushing techniques, and effective flossing practices. It will be adapted into Pakistani Sign Language with the original author’s consent and will be shared with students following completion of the intervention phase to ensure ongoing accessibility for children. Adaptation will be done by the replacement of the presenter, who will be signed in PSL, as the original video presenter was signing in ASL. The video will be recorded and asked video editor to replace the presenter while keeping everythign same. Oral health education will be delivered in groups of 25 students for three days. Participants will view the PSL video once in a controlled setting; unsupervised replay was not permitted before outcome assessment. Additionally, a video link will be shared with the students so they can rewatch the video at their convenience. The video will be uploaded to YouTube as an unlisted video, ensuring that only individuals with the direct link can access it, thereby maintaining a degree of privacy. Once uploaded, the YouTube link will be generated and distributed to students via email. To monitor student engagement, the view count of the video will be tracked through the YouTube Studio dashboard, which provides real-time analytics, including the number of views, average watch time, and audience retention. Yes, the video will be shared and made freely available to all children included in the study. 2. Intervention using Demonstration One sign language teacher trained by the researcher will give the demonstration and deliver the same message as in the video intervention, and last for 5 minutes same as the video. PI will have a one-hour face-to-face session with the SL teacher 1 week before live demonstration implementation to guide on the techniques to teach children. The teacher will be asked to strictly adhere to the messages and follow a script prepared by the researcher to maintain consistency. On the intervention day, the researcher will set up the demonstration table with the required materials. There will be no observation to monitor adherence to the intervention because it is not the objective of the study. The script has been developed from the video already. The teacher will introduce herself to a group of 25 students at a time and then inform them about the purpose of the demonstration. Then, she will give the demonstration according to the script. The video will also be shown to this group after 3 months.
