%X AIM: Investigation and evaluation of Pont's and Korkhaus indices of dental arch dimensions and comparison with Iranian adolescents' measurements.STUDY DESIGN: Descriptive and cross-sectional study.TIME AND PLACE OF STUDY: Department of Orthodontics, Shaheed Beheshti Medical Sciences University, School of Dentistry, Tehran, Iran, 2002.MATERIAL AND METHOD: Upper dental casts of 80 individuals with Class I occlusion (40 boys and 40 girls, mean age 14.11¡À0.82 years) were used.PRINCIPAL MEASUREMENTS: Seven variables were investigated and the results were analyzed using the statistical software SPSS and Excel. To determine correlation between mesiodistal width of teeth and dental arch width "Pearson Correlation¡± analysis was used. RESULTS: The results were as the followings: (a) There was a significant difference between anterior arch width of Iranian children (1.27¡À1.30) in comparison to suggested standard value (2.13¡À1.93) (p<0.001). (b) There was also a significant difference between posterior arch width (1.04¡À0.54) and of the corresponding standard value (1.52¡À1.22) (p<0.001). (c) The standard for anterior arch length (0.69¡À1.42) was significantly different from the suggested value (0.98¡À0.47) (p<0.001). (d) While Tonn¡¯s formula predicated the sum of upper incisors (SUI) value as 1.42¡À1.21, in this study it was found different (1.23¡À0.62). However, this difference was not statistically significant. CONCLUSIONS: According to the results of this study, maxillary dental arch dimensions of Iranian populations are different from the standard values published in major orthodontic references.
