To assess volume and surface of the mandibular condyle on cone beam computed tomography (CBCT) scans by comparing Class I, II, and III malocclusions.
CBCT scans of 55 patients were assessed to measure ANB angle, condyle volume, and surface by using VistaDent software. The values were compared between the different skeletal malocclusions and correlated to gender and sides. Kruskal-Wallis test was used for comparison of malocclusions and Mann-Whitney test and Wilcoxon test for comparisons of genders and sides. Statistical significance was defined as < 0.05.
There were no significant differences in volume ( = 0.588) and surface ( = 0.830) between the malocclusion classes. The comparison between sides showed a statistically significant difference for surface ( = 0.038).
Condylar volume and surface evaluated on CBCT scans showed no statistically different values for Class I, II, and III malocclusions.
通过比较安氏 I 类、II 类和 III 类错颌畸形，评估锥形束 CT（CBCT）扫描中下颌髁突的体积和表面积。
使用 VistaDent 软件评估 55 例患者的 CBCT 扫描，以测量 ANB 角、髁突体积和表面积。在不同的骨骼错颌畸形之间比较这些值，并将其与性别和侧别进行相关性分析。采用 Kruskal-Wallis 检验比较错颌畸形，采用 Mann-Whitney 检验和 Wilcoxon 检验比较性别和侧别。统计学意义定义为 < 0.05。
在体积（ = 0.588）和表面积（ = 0.830）方面，错颌畸形之间没有显著差异。侧别之间的比较在表面上有统计学显著差异（ = 0.038）。
在 CBCT 扫描中评估的髁突体积和表面积在安氏 I 类、II 类和 III 类错颌畸形之间没有统计学差异。
