Abstract:
Objective:To investigate the difference of condylar bone density,volume and surface area in adult female patients with different vertical skeletal features of skeletal Class Ⅱ.Methods:This study was a retrospective case-control study.150 female patients aged 18-30 years were included as the subjects.Lateral cephalic radiographs were measured and the cases with high angle,average an-gle and low angle of skeletal Class Ⅱ were included and respectively grouped(n=50),the CBCT images were collected,the condyles were reconstructed by Mimics Reseach 20.0 software,the bone density,volume and surface area of the condyles were measured.Univa-riate analysis of variance(ANOVA)was used to compare the difference of condyle measurements among the 3 groups.Results:The overall difference of condylar bone density,volume and surface area among the 3 groups were statistically significant(P＜0.05).Pair-wise comparison showed that the condyle bone mineral density in high angle group was lower than that in average angle group(P＜0.05),in average angle group was lower than that in low angle group(P＜0.05),in high angle group was lower than that in low angle group(P＜0.001).Condyle volume and surface area in high angle group were lower than those in low angle group(P＜0.05),in aver-age angle group was lower than those in low angle group(P＜0.001),in high angle group was lower than those in average angle group(P＞0.05).Conclusion:The condyle bone density,volume and surface area of the different vertical skeletal features of skeletal class Ⅱ in adult female patients are different.
