Process of the validation of the video.

Presently, in Nigeria, as in many other developing countries, oral health promotion programs remain the responsibility of the public health dentists. This responsibility is now being threatened, particularly with persistent short supply of dentists in general. Recent evidence showed that peers and school-teachers trained by dentists can effectively anchor oral health promotion programs. However, the sustainability of this method of oral health promotion is further threatened by the emigration of dentists needed to train these peers and teachers. Therefore, the assessment of the feasibility of a training alternative, such as the use of pre-recorded video, has become crucial. This study reports the development and validation of an animated video as an oral health training tool for adolescents and teachers in Ibadan, Nigeria. The narrative video was developed by a team of experts from various specialties, which included public health dentists, pediatric dentists, epidemiologists, communication scientists, animation experts, dental surgery residents, a pediatric surgeon, and science educators. The steps involved in the development included pre-video production research, development of the key oral health education messages, development of the script and storyboarding, creation, design, and selection of characters, visual style decision, voice-over narration recording, production, and post-production processing. The script for the video was developed from information adopted from a manual on oral health care of students. The video produced was validated for face and content quality among dentists, teachers, and adolescents in secondary schools through individual feedback and focus group discussions. Relevant comments and observations were considered in the final editing and postproduction process to yield a final video after series of editing. The video was found to be simple to use, clearly illustrative and highly educative. This is a report on the development, production, and validation of the School Oral Health Promotion Program animated video for training adolescents and teachers.当前，与诸多其他发展中国家一样，尼日利亚的口腔健康促进（Oral Health Promotion）项目仍由公共卫生牙医（Public Health Dentists）负责。这一职责如今正面临挑战，尤其是在牙医整体持续短缺的背景下。近期研究证据表明，由牙医培训的同龄学生与学校教师可有效承接口腔健康促进项目。然而，这类口腔健康促进方式的可持续性进一步受到威胁——因负责培训上述人员的牙医出现了外流情况。因此，评估采用预录制视频（pre-recorded video）等替代培训方案的可行性变得至关重要。本研究报告了一款动画视频（Animated Video）的开发与验证过程，该视频可作为尼日利亚伊巴丹地区青少年与教师的口腔健康培训工具。该叙事类视频由多学科专家团队共同开发，成员涵盖公共卫生牙医、儿童牙医（Pediatric Dentists）、流行病学家（Epidemiologists）、传播科学家（Communication Scientists）、动画专家（Animation Experts）、口腔外科住院医师（Dental Surgery Residents）、儿科外科医师（Pediatric Surgeon）以及科学教育工作者（Science Educators）。其开发流程包括视频前期制作调研、核心口腔健康宣教内容拟定、脚本与分镜创作、角色的创作设计与遴选、视觉风格确定、旁白录制、制作及后期处理。该视频脚本改编自一份针对学生口腔保健的手册。制作完成的视频通过个体反馈与焦点小组讨论（Focus Group Discussions），邀请牙医、教师与中学青少年对其表面质量与内容质量进行验证。在最终剪辑与后期制作阶段纳入所有相关意见与观察结果，经多轮剪辑后生成终版视频。该视频被评价为使用简便、演示清晰且极具教育意义。本报告即围绕这款用于青少年与教师培训的学校口腔健康促进项目动画视频的开发、制作与验证过程展开。
