Relationship between inter-molar, inter-canine, and inter-gonion widths in children aged 6–9 years

The mixed dentition stage of tooth development is critical as it often involves changes in the inter-molar and inter-canine widths of the dental arch, which may affect the inter-gonion width. It was hypothesized that the relationship between the inter-molar, inter-canine, and inter-gonion widths could be used to estimate the width of the dental arch, thus allowing better treatment planning. This research aimed to determine the relationship between the inter-molar, inter-canine, and inter-gonion widths in children aged 6–9 years old. This cross-sectional study used 30 study models and panoramic radiographic images of pediatric patients in Teaching Dental Hospital, Faculty of Dentistry, Universitas Indonesia. The results showed that the inter-molar and inter-gonion widths and the inter-canine and inter-gonion widths exhibited weak correlations that were not statistically significant (r = 0.277, r = 0.032, respectively). However, the inter-molar and inter-canine widths demonstrated a strong, statistically significant correlation (r = 0.580).
