Numerous factors such as the direction of mandibular growth, head posture, inclination of teeth and the oral and perioral musculature may affect the development and severity of crowding.7 Research into the relationship between crowding and cephalometric measurements has been sparse.
Baccetti et al reported an increase of 0.5mm (93.5 to 94.0) in the mean value of maxillary apical base length (Co-A) and an increase of 1.0mm (120.5 to 121.5) in the mean value of mandibular base length (Co-Gn); both termed insignificant.10 Since crowding increases with age regardless of changes in mandibular apical base length, it would make reduced base lengths in childhood a possible indicator for dental crowding in adulthood if a positive correlation existed.
There is 3mm of maxillary crowding and 5mm of mandibular crowding.
Treatment Objectives: The objectives in this case were to resolve the maxillary crowding with interproximal reduction.
The findings not only debunk myths and assumptions regarding tolerance of
crowding among ethnic groups but also have implications for urban planning.

Dental crowding can be defined as a discrepancy between tooth size and arch size that results in maloc- clusion.1 The causes of crowding have not totally been understood but evolutionary reduction in jaw size and tooth size has been implicated.2 Evolutionary decrease in jaw size without corresponding reduction in tooth size has been reported as the major culprit to dental crowding.
