Implications of Permanent Teeth Dimensions and Arch Lengths on Dental Crowding during the Mixed Dentition Period

Dento-alveolar disharmony with crowding is a common reason for orthodontic treatment not fully understood or unequivocally demonstrated causes. This study investigated the correlations between teeth dimensions, arch lengths, and during mixed dentition period. A cross-sectional on 100 dental casts of patients class I malocclusions was performed. Dental arches were classified as non-crowded, moderately crowded, severely spaced. The mesio-distal widths, bucco-lingual sizes, crown proportions permanent assessed. results indicated that length measurements showed smaller values in crowded arches. dimensions upper central incisors lower lateral larger crowding. decreased, first molars increased Upper presented cases. Low negative found diameters maxillary incisors, molars, space discrepancies. In conclusion, could be associated reduced increase sizes variations molars.
