The objective of this 2-arm parallel trial was to investigate the recall and comprehension of the information of orthodontic patients undergoing fixed orthodontic treatment using either the verbal explanation supported with the British Orthodontic Society (BOS) leaflet or 3-dimensional (3D) animated content.
Patients aged 12-18 years, with no relevant medical history or learning and reading difficulties, who were to undergo orthodontic treatment, were randomized to receive information about fixed orthodontic treatment, using either verbal explanation supported with the BOS leaflet or 3D animated content on the basis of the BOS leaflet. Randomization was performed by block randomization; block size of 4 was used, from which 6 blocks with 6 different sequences (AABB, ABBA, ABAB, BBAA, BAAB, BABA). The blinded author asked patients a series of open-ended questions. The primary outcome measure was the total score of the questions. An independent 2 sample t test was conducted to determine if there was a statistical difference in total questions score between the conventional method (verbal and leaflet) and the 3D animation at the time of consent taking (T0) and again 1 year later (T1). The secondary outcome measure was the time spent by the clinician delivering the information to the patient.
Thirty-two patients were randomized into each group. After 1 year, 1 patient was lost in each group. At the time of consent, the conventional group scored 79.1 ± 18.4 compared with 76.4 ± 12.8 for the 3D animation group with no statistically significant difference (95% confidence interval, -11.0 to 5.3), (P = 0.492). One year later, again, there was no statistically significant difference (P = 0.639) between the conventional group (75.6 ± 12.3) and the 3D animation group (74.4 ± 9.0) (95% confidence interval, -7.0 to 4.4). The average exposure time to the educational intervention in the conventional group was 8.5 minutes more than the 3D animation group.
The use of 3D animation or verbal and leaflet information is relatively equivalent in transferring knowledge to the orthodontic patient. The use of a 3D animated video reduces the clinician time needed in the clinic to deliver information to the patients and also allows multiple views and better suits the younger generation. Patients undergoing short- or long-term orthodontic treatment do not recall root damage as a risk of orthodontic treatment, which requires special attention from the orthodontist to reinforce this information.

本双盲双臂平行试验旨在探究接受固定正畸治疗的正畸患者对正畸信息的回忆和理解，信息传达方法为口头讲解联合英国正畸学会（BOS）手册或基于 BOS 手册的 3D 动画。
纳入无相关病史或学习、阅读困难、年龄在 12-18 岁之间、即将接受正畸治疗的患者，随机分为口头讲解联合 BOS 手册或基于 BOS 手册的 3D 动画两组，接受固定正畸治疗相关信息。采用区组随机化（block randomization），区组大小为 4，共 6 个区组，每个区组 6 个不同的序列（AABB、ABBA、ABAB、BBAA、BAAB、BABA）。盲法作者向患者提出一系列开放性问题。主要结局指标为问题总得分。采用独立两样本 t 检验比较两组在知情同意时（T0）和 1 年后（T1）的总问题得分是否存在统计学差异。次要结局指标为医生向患者传达信息的时间。
每组 32 名患者随机分组。1 年后每组各失访 1 例。知情同意时，常规组得分为 79.1±18.4，3D 动画组为 76.4±12.8，差异无统计学意义（95%置信区间：-11.0 至 5.3）（P=0.492）。1 年后，常规组（75.6±12.3）与 3D 动画组（74.4±9.0）差异亦无统计学意义（P=0.639）（95%置信区间：-7.0 至 4.4）。常规组的平均暴露时间比 3D 动画组多 8.5 分钟。
与口头讲解联合 BOS 手册相比，3D 动画在向正畸患者传授知识方面效果相当。3D 动画可以减少医生向患者传达信息的时间，提供更多视角，更适合年轻一代。接受短期或长期正畸治疗的患者不会将牙根损伤视为正畸治疗的风险，这需要正畸医生特别注意加强这方面的信息。
