Abstract
The volumetric relationship between the tongue and the oral cavity may be a decisive factor in aligning teeth; some types of malocclusions can be caused by a volumetric imbalance. If the tongue is large relative to the oral cavity, it moves backwards, causing obstruction of the oropharyngeal airway. These disorders are usually associated with obstructive sleep apnea. There are several studies that have relied on application of CBCT as an accurate and reliable volumetric measurement of three-dimensional radiation of the tongue. Some of these studies were able to measure the ratio between the size of the tongue and the volume of the oral cavity and the effect of this ratio on the upper airway. However, few if not studies have measured this ratio exclusively in skeletal class II cases.
