Abstract
The present study was carried out to examine the extent to which tooth size and jaw size each contribute to dental crowding. Two groups of dental casts were selected on the basis of crowding. One group exhibited gross dental crowding and the second group little or no crowding. Means and standard deviations of the following parameters were treated to statistical analysis.
1) Collective Mesiodistal tooth widths.
) Arch perimeters.
) Buccal arch widths.
) Lingual arch widths.
Statistically there were no significant differences in the collective mesiodistal teeth dimensions but significant differences were found between the dental arch dimensions of the two groups. The crowded group was found to have smaller dental arch dimensions than the noncrowded group.
