Abstract
Dental arch form and dimension are fundamental factors in orthodontic diagnosis and treatment planning. Its dimension will increase due to the eruption of teeth and also affected by ethnicity, nutrition, systemic disease, hormonal factors, and gender. There are many teeth erupt in 8-10 years old children. The aim of this study was to assess the correlation between age and dental arch dimension of Javanese children in good nutritional status for consideration of orthodontic treatment. This was a cross-sectional study with 66 children aged 8 to 10 years in normal dentoskeletal relationship, grouped based on the age as the subject. Each group consisted of 22 pairs of dental study model, male and female. Anterior and posterior size of dental arch length were measured by digital sliding calipers from midpoint between right and left permanent central incisors perpendicular to intercanines and intermolars. The width were measured at intercanines and intermolars. Pearson-s correlation test showed that there were significant correlations between age and maxillary dental arch lengths (p=0.01, r=0.310 for anterior and p=0.043, r=0.249 for posterior). Based on this study, it can be concluded that there was a correlation between age and dental arch length of 8 - 10 years old Javanese children in good nutritional status.
