The purpose of this study was to investigate the relationship between the size and
position of tongue, position of teeth, and orofacial morphology during growth period.
The subjects used in this study were 172 children, ranging from 7 to 13 years of age,
without anatomical abnormalities or aberrant oral habit.
Cephalometric radiographs and study models were used to evaluate the size and
position of tongue, position of teeth, orofacial morphology and their relationships.
The obtained results were as follows :
1. The average distance of Ul -M was 20.1§® in deepbite group, 19.0§® in normal
group, 16.1 §® in anterior crossbite group, and 15.5§® in open bite group. There was a
statistical significance among groups (P<0.01).
2. There was generally low correlation between the size and length of tongue, size of
arch on the dental cast, and the position of teeth(r=0.25-0.49).
3. There was moderate correlation between the size and length of tongue, and anterior
facial height in normal group and deepbite group(r=0.40-0.69).
4. The position of teeth showed close correlation with anteroposterior position of the
tongue than that of vortical position in openbite group and anterior crossbite
group(y=0.32-0.66).
5. There was low correlation between the size and length of tongue, anterior facial
height, and posterior facial height in deepbite group(r=0.30-0.40).
6. There was moderate correlation between the vertical position of tongue, ODI, and
APDI in anterior crossbite group(r=0.45 , r=0.54 ).
In conclusion, morphologic patterns of the tongue were thought to be factors which
influence the size of arch, position of teeth, and orofacial morphology, which play an
important diagnosticrole in children malocclusion treatment.
