研究食物硬度对儿童咀嚼行为的影响。健康儿童（3-17岁）根据他们的牙萌出阶段平均分为五组。每个参与者吃软的和硬的粘弹性测试食物模型（各3个），同时记录双侧咬肌的三维下颌运动和肌电图（EMG）活动。将儿童的数据与健康成年人（18-35岁）对照组进行比较。数据采用非参数检验进行分析。儿童组和成人组的咀嚼周期数和咀嚼序列持续时间无显著差异。与成人相比，乳牙期儿童（3-5岁）在咀嚼序列结束时表现出更短的下颌侧向运动和更高的肌肉活动。此外，儿童的年龄组（3-14岁）未能使他们的下颌肌肉活动适应食物硬度。然而，在恒牙期后期（15-17岁），儿童能够进行类似成人的咀嚼行为。总的来说，3岁的孩子似乎就能像成年人一样完成基本的咀嚼功能。然而，有不同的预期或适应下颌肌肉活动和下颌运动学食物硬度。这项研究可能对诊断和治疗与牙齿咬合不正和其他口面功能障碍相关的咀嚼障碍儿童具有临床意义。
To investigate the effects of food hardness on chewing behavior in children compared with adults. Healthy children (3–17 years) were equally divided into five groups based on their dental eruption stages. Each participant ate soft and hard viscoelastic test food models (3 each), while the three-dimensional jaw movements and electromyographic (EMG) activity of the bilateral masseter muscles were recorded. The data from the children were compared with a control group of healthy adults (18–35 years). The data were analyzed with nonparametric tests. There was no significant difference in the number of chewing cycles and the duration of the chewing sequence between children groups and adults. Children with primary dentition (3–5 years) showed shorter lateral jaw movement and higher muscle activity at the end of the chewing sequence, compared with adults. Further, children’s age-groups (3–14 years) failed to adapt their jaw muscle activity to food hardness. However, at the late-permanent dentition stage (15–17 years), children were capable of performing adult-like chewing behavior. Overall, it seems that children as young as 3-year-old are quite competent in performing basic chewing function similar to adults. Yet, there are differences in the anticipation or adaption of jaw muscle activity and jaw kinematics to food hardness. The study may have clinical implication in the diagnosis and management of children with chewing impairment associated with dental malocclusions and other orofacial dysfunctions.
