title: Tooth size discrepancies among Jordanian schoolchildren.
abstract: The aims of this study were to determine the tooth size discrepancies (TSD) in a representative sample of Jordanian schoolchildren and to compare TSD between genders. Dental casts of 367 (174 males and 193 females; mean age 15.5 years) Jordanian schoolchildren were selected. Anterior and overall Bolton ratios were determined using a digital calliper. Differences between genders were analyzed using a t-test. The results showed that there were no significant differences in the TSD between males and females. The percentages of subjects with more than 2 standard deviations for the anterior and overall ratios were 23.7 and 9.5, respectively.
