Dental anxiety distresses children and their families with consequent poor oral health and costly pediatric dental services. Children's behaviors could be modified using a distraction technique for improved dental treatment. The study evaluates the effects of an audio-visual distraction on children's behaviors and pain expressions during dental treatment.
One hundred healthy children, between 4 and 6 years of age, were randomly assigned to one of two groups: audio visual distraction (AVD, N = 61) group and control (CTR, N = 39) group. The pre and post pain expression was collected using a faces pain rating scale from the participated children. Children's behavior was evaluated using the Frankl behavior rating scale by the assigned dentist. Data was analyzed using chi-squared tests and analysis of variance.
The AVD group demonstrated more "definitely positive" behavior (91.8%) compared to the CTR group (35.9%) based on the Frankl scale evaluation from pre- and post-treatment (p < 0.0001). The pain rating scale did not demonstrate a significant difference in post-treatment pain scales (p = 0.2073) or changes in pain (p = 0.1532) between the AVD group and CTR group.
The AVD is an effective distraction tool for young children during dental treatment regardless of child's subjective pain expression.
儿童的牙科焦虑会给他们自己和家人带来困扰，导致口腔健康状况不佳和儿童牙科治疗费用高昂。可以使用分散注意力的技术来改变儿童的行为，从而改善牙科治疗效果。本研究评估了视听分散注意力对儿童在牙科治疗过程中的行为和疼痛表现的影响。
将 100 名 4 至 6 岁的健康儿童随机分为视听分散注意力（AVD）组（n=61）和对照组（CTR）组（n=39）。使用参与儿童的面部疼痛评分量表收集治疗前后的疼痛表达。由指定的牙医使用 Frankl 行为评分量表评估儿童的行为。使用卡方检验和方差分析对数据进行分析。
根据治疗前后的 Frankl 量表评估，AVD 组表现出更“肯定积极”的行为（91.8%），而 CTR 组为 35.9%（p<0.0001）。疼痛评分量表显示，在治疗后的疼痛评分量表（p=0.2073）或疼痛变化（p=0.1532）方面，AVD 组和 CTR 组之间没有显著差异。
无论儿童的主观疼痛表现如何，视听分散注意力都是儿童牙科治疗中一种有效的分散注意力工具。
