摘　　要：目的:利用CBCT研究不同矢状骨面型儿童及青少年腭中缝分期(MPS)在不同性别和年龄段的差异性。方法:选取2020—2023年天津市口腔医院正畸科就诊的600例6~20岁患者的CBCT影像资料,根据ANB角将其分为Ⅰ、Ⅱ、Ⅲ类矢状骨面型,每组200例;按年龄分为6~10岁、11~13岁、14~16岁、17~20岁4组,每组50例;按照文献方法将MPS分为A、B、C、D、E、F 6期;使用卡方检验分析性别和年龄因素对MPS分布的影响。结果:MPS在不同性别间分布差异显著(χ^(2)=12.872,P<0.05)。C期的受试者人数最多,男性C期103例(34.33%)、女性C期93例(31.%)。A~C期受试者人数男性多于女性。E~F期受试者人数女性多于男性。不同矢状骨面型MPS在同性别中分布无差异(均P>0.05)。6~10岁和17~20岁女性不同矢状骨面型MPS的分布差异有统计学意义(χ^(2)=15.237、13.63,均P<0.05)。6~10岁MPS的分布主要处于A~C期,17~20岁MPS主要处于E~F期。结论:不同矢状骨面型儿童及青少年MPS在不同性别的分布无显著差异。不同矢状骨面型女性在6~10岁和17~20岁年龄段的分布存在显著差异。Objective:To investigate the variability of midpalatal suture stage(MPS)in children and adolescents with different sagittal facet types in different gender and age groups using CBCT.Methods:The CBCT imaging data of 600 patients aged 6-20 years in the Department of Orthodontic of Tianjin Stomatological Hospital from 2020 to 2023 were selected and classified into classⅠ,classⅡ,and classⅢsagittal facet type according to ANB angle,200 cases in each group.Based on age,patients were classified into four groups of 6-10 years old,11-13 years old,14-16 years old,and 17-20 years old,50 cases in each group.MPS was classified into A,B,C,D,E,and F,6 stages according to Gaolu′s midpalatal suture staging method.The effects of gender and age factors on the distribution of MPS were analyzed using the chi-square test.Results:The difference in the distribution of MPS between genders was significant(χ^(2)=12.872,P<0.05).Stage C had the largest number of subjects,with 103(34.33%)males and 93(31.%)females in stage C.The number of male subjects in stages A to C was higher than that of females.The number of subjects in stages E to F was more females than males.There was no difference in the distribution of different sagittal facet types of MPS among the same gender(all P>0.05).The difference in the distribution of different sagittal facet types of MPS between females aged 6-10 years and 17-20 years was statistically significant(χ^(2)=15.237,13.63,both P<0.05).The distribution of MPS in ages 6-10 years was mainly in the A to C stage,and the distribution of MPS in ages 17-20 years was mainly in the E to F stage.Conclusion:The distribution of MPS in children and adolescents with different sagittal facet types do not differ significantly between genders.There is significant difference in the distribution of females with different sagittal facet types in the age groups of 6-10 years and 17-20 years.
