Abstract
The purpose of this study was to find whether there is a correlation between tooth size and jaw size. Dental stone models and cephalometric radiographic films of 87 untreated individuals were evaluated. Repeated measurements of the maximum mesiodistal width of the teeth were taken by means of a digital vernier caliper. Linear measurements of jaw size were assessed by means of a digitizer and Visual C++ program. All measurements were taken separately according to the subject´s gender. To determine the relationship between jaw and tooth size, the Pearson correlation was used.
The results were as follows:
1. Male and female subjects showed a statistical difference in regard i,o tooth size and jaw size
2. In contrast to the results of the male subjects, there were no statistically significant correlations between maxillary size and maxillary teeth size in female subjects
3. In male subjects, the two maxillary sizes of PTM vert-ANS vest (FH plane) and PTM vent-A vent (palatal plane) were significantly correlated with themaxillary teeth size. Especially, the size of the upper central incisor showed significant correlation with all maxillary sizes.
4. In both male and female subjects, mandibular size B vert- Point J vert (mandibular plane) showed significant correlation with mandibular teeth size.
As gleaned from the results of this study, the relationship between jaw size and tooth size was fair or little in natural occurring good occlusion.
