Abstract

Aims:To study the correlation between, upper and lower pharyngeal airway dimensions in untreated Class I, Class II, Class III malocclusions Methods and Material: Our Sample consisted of 400 patients divided into three groups according to their ANB Values, Class I: ANB 1-3, Class II: ANB >4, Class III: <0. Lateral Cephalograms were used for the study. Statistical analysis used: In each of the groups, the means and standard deviation for the ages, and upper and lower airways, were determined. The comparisons between all the groups, were performed by using the 1-way ANOVA at P<.05 Results: There is a decrease in upper and lower airway width from Class I to Class II to Class III. However it has shown no statistical significance. Conclusions: Upper and lower airway does not have any significant influence on the type of malocclusion. Key Messages: Lower airway decreases from Class I to Class II to Class III malocclusion patients. Patients with Class III malocclusions have the lowest lower airway dimensions and these patients may be more prone to mouth breathing as a result of their relatively diminished pharyngeal dimensions. Small pharyngeal spaces in Class III patients are probably due to large tongue.
