This was a randomised controlled trial (RCT).
Participants were randomised to viewing positive images of dentistry and dental or dentally neutral photographs for 2 min in the waiting area prior to their appointment.
Anticipatory anxiety assessed by the Venham Picture Test.
A significant difference in anticipatory dental anxiety was found between the two groups (median-positive images, 0; median-neutral images, 3; P<0.001). Anticipatory anxiety was not correlated with age (0.04; P>0.05) and there was no significant difference between male and female participants in their level of anticipatory anxiety (median for males, 0.5; median for females, 1; P>0.05).
Viewing positive images of dentistry and dentists results in short-term reductions in anticipatory anxiety in children.
这是一项随机对照试验（RCT）。
参与者在预约前被随机分配，在候诊区观看牙科正面图像以及牙科或牙齿中性照片2分钟。
通过维纳姆图片测试评估预期焦虑。
两组之间预期牙科焦虑存在显著差异（正面图像中位数为0；中性图像中位数为3；P<0.001）。预期焦虑与年龄无关（0.04；P>0.05），男性和女性参与者在预期焦虑水平上没有显著差异（男性中位数为0.5；女性中位数为1；P>0.05）。
观看牙科和牙医的正面图像可使儿童的预期焦虑在短期内降低。
