| Research Abstract |
Because the chewing motion dramatically changes by the occlusal condition, the relationship may hold among three developmental factors: "feeding behavior ⇔ chewing motions ⇔ occlusal condition". From results of analyzing feeding behaviors and chewing motions, smaller within-individual variations, compared to between-individual variations, were observed in adults. On the other hand, it is well knownthat occlusal condition is dominated by lip closure pressure, tongue motion and masticatory muscles even in younger children. The establishment of stable motions with smaller within-individual variations is affected by these elements. Therefore it might be suggested that the occlusal condition also affectedfeeding behaviors.
