This randomised clinical trial aimed to compare the effects of multimedia information and verbal explanations on patients' knowledge and anxiety as primary outcomes and decision-making as a secondary outcome.
One hundred patients needing dental replacement were randomly assigned (1:1) to either a multimedia group (n = 50) or a verbal group (n = 50). They completed self-administered questionnaires covering demographics, confidence with their awareness level, knowledge (score 0-5), anxiety (score 5-25) and decision-making before and after receiving either a multimedia or verbal explanation of implant surgery.
Knowledge scores increased significantly in both groups (p < 0.001), rising from 1.96 to 3.90 in the multimedia group and from 2.00 to 3.98 in the verbal group. Anxiety levels also declined markedly over time (p < 0.001), dropping from 12.76 to 11.48 (multimedia) and from 13.92 to 12.16 (verbal). Neither the group effect nor the interaction effect was significant. No significant difference in decision change was observed in either the multimedia (p = 0.289) or verbal (p = 0.146) groups. Most patients in both groups relied on their dentist's recommendation regarding whether to proceed with freehand or CAIS, even after receiving the interventions. Meanwhile, cost remained a significant barrier to proceeding with implant therapy in both groups.
Both multimedia and verbal interventions significantly improved patient knowledge and reduced anxiety, although the magnitude of anxiety reduction was modest. Changes in decision-making were limited and largely influenced by cost and the dentist's recommendation. Given this single-centre design and modest sample size, caution is advised when generalising these findings.
本随机临床试验旨在比较多媒体信息和口头解释对患者知识水平和焦虑程度（作为主要结局）以及决策制定（作为次要结局）的影响。
100名需要进行牙齿修复的患者被随机（1:1）分配至多媒体组（n = 50）或口头组（n = 50）。在接受关于种植手术的多媒体或口头解释之前和之后，他们完成了涵盖人口统计学、对自身认知水平的信心、知识（0 - 5分）、焦虑（5 - 25分）以及决策制定的自填式问卷。
两组患者的知识得分均显著提高（p < 0.001），多媒体组从1.96分升至3.90分，口头组从2.00分升至3.98分。随着时间推移，焦虑水平也显著下降（p < 0.001），多媒体组从12.76降至11.48，口头组从13.92降至12.16。组间效应和交互效应均不显著。多媒体组（p = 0.289）和口头组（p = 0.146）在决策变化方面均未观察到显著差异。两组中的大多数患者即使在接受干预后，在是否进行徒手种植或计算机辅助种植手术方面仍依赖牙医的建议。同时，费用仍然是两组患者进行种植治疗的一个重大障碍。
多媒体和口头干预均显著提高了患者的知识水平并减轻了焦虑，尽管焦虑减轻的幅度较小。决策制定的变化有限，且很大程度上受费用和牙医建议的影响。鉴于此单中心设计和样本量较小，在推广这些研究结果时应谨慎。
