Abstract：
BACKGROUND Effective communication and patient education are important in geriatric dental care. Memory decline complicates patient adherence. This study aimed to compare verbal, audio, and video patient education material (PEM) and adherence to dental prosthetic management in edentulous patients. MATERIAL AND METHODS 90 completely/partially edentulous patients (aged 40 to 70 years), were divided (simple random) into three groups (Gp) of 30 each . A total of 68 instructions were organized into 9 learning categories. For GpVi, a 20 minute video was shot using a Sony camera (PD170), with two actors depicting related PEM information. Patients were recalled after 1 day and 7days, to recall the PEM instructions. A Denture plaque Index (DPI) determined the efficiency of the instructions at both time intervals. Frequencies, means and standard deviations were derived for each group and then compared using Chi square, paired and unpaired t test and a Neuman-Keul post hoc pairwise test. All significant differences were kept at probability t value of ≤0.05. RESULTS PEM instructions related to patient individuality, proper tongue position and miscellaneous showed poor patient recall. At 1 day interval, audio was found to have better recall than video and verbal in 5 PEM instruction categories. At 7 day interval, video showed better recall than other two groups (P≤0.05). Despite improvements in patients recall, DPI revealed better denture hygiene maintenance in patients receiving instructions through video format (P≤0.05). CONCLUSIONS For all categories, no single media was considered to be sufficient, audio produced early better recall while video influenced long term recall and better denture hygiene maintenance.
摘要：
背景技术有效的沟通和患者教育在老年牙科护理中是重要的。记忆力下降使患者的依从性复杂化。本研究旨在比较口头，音频,和视频患者教育材料（PEM）以及无牙患者对牙齿修复管理的依从性。材料与方法90例完全/部分无牙患者（40至70岁），（简单随机）分为三组（Gp），每组30人。总共68个指令被组织成9个学习类别。对于GpVi来说,使用索尼相机（PD170）拍摄了20分钟的视频，有两个演员描绘相关的PEM信息。患者在1天和7天后被召回，调用PEM指令。义齿菌斑指数（DPI）确定了两个时间间隔的说明效率。频率,得出每组的平均值和标准偏差，然后使用卡方进行比较，配对和未配对t检验以及Neuman-Keul事后配对检验。所有显著差异保持在概率t值≤0.05。结果与患者个性相关的PEM说明，正确的舌位和杂项显示患者记忆力差。间隔1天，在5个PEM教学类别中，音频被发现比视频和口头有更好的回忆。间隔7天，视频显示召回率优于其他两组(P≤0.05)。尽管患者的回忆有所改善，DPI显示通过视频格式接受指导的患者的义齿卫生维护更好（P≤0.05）。结论对于所有类别，没有一种媒体被认为是足够的，音频产生早期更好的回忆，而视频影响长期回忆和更好的义齿卫生维护。
