To evaluate the effect of video modelling on the reduction of dental anxiety (DA) in children receiving fissure sealants.
A parallel double-blind randomised clinical trial (RCT) was conducted between February and August 2017 in a hospital in Madinah (Saudi Arabia). A statistically calculated sample size (n=48) of children (6-10) years old was randomly assigned to either a modelling or a control video group. Before and after watching the relevant video, DA was assessed by means of the Abeer Children Dental Anxiety Scale (ACDAS).
There was a significant difference in dental anxiety scores between the modelling and the control groups after watching the videos, P<0.001. Children aged 7-8 years reported the highest dental anxiety scores. There was no significant difference between the results of DA that were reported by the child on ACDAS at the time of dental examination with a mirror, and expected behaviours of the children that were reported by their mothers before the start of the dental treatment, P=0.33.
Video modelling seems to be an effective method to reduce dental anxiety in children receiving fissure sealants. The mother's expectation of her child's behaviour appears to be a good indicator of the child's actual behaviour at the dentist.
评估视频示范对接受窝沟封闭的儿童减少牙科焦虑症（DA）的效果。
这是 2017 年 2 月至 8 月在沙特阿拉伯麦地那的一家医院进行的一项平行、双盲、随机对照临床试验（RCT）。通过统计学计算，将 6-10 岁的儿童（n=48）随机分配到示范视频组或对照视频组。在观看相关视频前后，采用 Abeer 儿童牙科焦虑量表（ACDAS）评估 DA。
观看视频后，示范组和对照组的牙科焦虑评分有显著差异，P<0.001。7-8 岁的儿童报告的牙科焦虑评分最高。在使用镜子进行牙科检查时，儿童在 ACDAS 上报告的 DA 结果与母亲在牙科治疗开始前报告的儿童预期行为之间无显著差异，P=0.33。
视频示范似乎是一种减少接受窝沟封闭的儿童牙科焦虑的有效方法。母亲对孩子行为的期望似乎是孩子在牙医处实际行为的良好指标。
