Evaluation of arch width
variations among different skeletal patterns in South Indian population.
To our knowledge this paper is one of the first studies that shows a correlation between the comparison of bizygomatic and bigonial arch widths
and some socioemotional aspects and personality traits.
A longitudinal study of dental arch width
at the deciduous second molars on children 4 to 8 years of age.
: The maxillary arch width
was significantly less in the affected group compared with healthy controls in all dimensions, P values were less than 0.
The objective of this study was to evaluate the respiratory pattern in children in the mixed dentition by means of acoustic rhinometry and its relation to the upper arch width
6],  Presumably, the reduction in the posterior arch width
was due to the loss of anchorage.
8 Arch width
has been a subject of interest among investigators; studying the growth of dental arches.
The premolar arch width
was taken from the first premolar of the left side to the right side at the distal end of its occlusal groove.
It is generally accepted that an important relationship exists between the arch width
and vertical facial morphology.
The results showed that the difference in arch width
was statistically significant along all points of measurement between crowding and non-crowding group in both the genders with the crowding group having smaller arch dimensions in both the genders.
Assessment of arch width
and arch depth is one of the most important diagnostic criteria for a maloc- clusion.
Conclusion: In class III malocclusion, almost all the dental arch width
measurements in maxilla were smaller and mandibular dental arch width
measurements were lager as compared to normal class I normal occlusion.
