Abstract

SKELETAL CLASSIFICATIONS OF JAWS

Subjects and methods: cross-sectional study of


90 subjects with different skeletal classifications (30 samples in class I, 30 samples in class II, 30 samples in class III) examined and treated at School of Odonto- Stomatology – Hanoi Medical University. Results: width of nasopharyngeal class I: 24.9 ±2.97, class II: 25.55 2.9, class III: 24.52 2.88; width of oropharyngeal class I: 10.12 ± 3.58, class II: 8.92 ± 2.97, class III: 10.17 ± 3.71 mm; width of hypopharyngeal class I: 16.98 ± 4.33, class II 16.45 ± 3.64, class III: 18.48 ± 4.3 mm; soft palate thickness class I: 8.5 ± 1.5, class II 7.53 ± 1.75, class III: 8.45


± 1.83 mm; soft palate length class I: 32.78 ± 4.15, class II: 33.26 ± 3.45, class III: 30.71 ± 4.77 mm;


tongue length class I: 68.08 ± 6.59, class II: 66.18 ± 6.64, class III: 66.22 ± 5.21 mm; tongue height class I: 34.7 ± 3.26, class II: 32.83 ± 4.12, class III: 35.65


± 3.88 mm. Conclusion: the nasopharyngeal airway width in class II subjects is more than class I, and in class I subjects is more than class III. The oropharyngeal, hypopharyngeal airway width in class III subjects are more than class I and class I subjects are more than class II, but not significantly. Soft palate length in class II subjects is more than class I and in class I subjects is more than class III. Tongue length, soft palate thickness in class I subjects are more than class III and in class III subjects are more than class II.
