Abstract

Abstract:

BACKGROUND: Location relationship between maxillary incisor labial inclination and the thickness of anterior alveolar bone displays ethnic and regional differences.
OBJECTIVE: To study the correlation of alveolar bone structure and incisor labial inclination in adolescents with skeletal class II malocclusion in Uygur and Han populations of Xinjiang, China.
METHODS: Sixty Uygur and 60 Han patients at 11-16 years of age (average 13.8 years old), 32 males and 28 females, with skeletal class II malocclusion were included. The thickness of anterior alveolar bone and incisor labial inclination were measured on lateral cephalometric films, and the results were analyzed using SPSS 17.0 statistical software.
RESULTS AND CONCLUSION: In Han and Uygur populations, palatal alveolar bone thickness in maxillary incisor region was significantly negatively correlated with the inclination of maxillary incisor (r=-0.715 for Han, r=-0.651 for Uygur, P < 0.05), while labial alveolar bone thickness in mandibular incisor region was significantly positively correlated with the lower incisor inclination (r=0.902 for Han, r=0.745 for Uygur, P < 0.05). These results indicate that the palatal alveolar bone thickness in maxillary incisor region decreases with the increase of the inclination of maxillary incisor; however, the labial alveolar bone thickness in mandibular incisor region increases with the increase of the lower incisor inclination.
