Abstract

The chewing power of individuals in producing food particles into smaller sizes is different from one another. A chewing power of individual is associated with Free Way Space. Free Way Space is the distance between the maxillary and mandibular occlusal surface at rest position. Differences in topography was also related to a person chewing power, which is due to a different diet. The purpose of this study was to determined the effect of the Free Space Way, topography, and gender to the chewing power of children aged 7-8 years.

This was a quasi-experimental study. The number of subjects were 40 children . The subjects were divided into 2 groups: 20 children who lived in the highlands and 20 children who lived in the lowlands, each distinguished by a gender and the size of Free Way Space. Every child chew a carrot in accordance with the instructions, the results were accommodated, and count the food particles that got through mesh 4, 8, and 10 to see the chewing power of children.

Data were analyzed by multivariate Anova parametric test. The results showed significant (p < 0.05), that the size of the Free Way Space, topography , and gender influence the chewing power of children. Interaction between Free Way Space, topography, and gender to influence the chewing power of children also showed significant result (p<0,05). The conclusion of this study for children aged 7-8 years was the child with a large Free Way Space has stronger chewing than the children with Free Way Space smaller, a child who lived in the highlands has stronger chewing than in the lowlands, as well as boy has a stronger chewing than girl.
