Abstract

Introduction: This study aimed to evaluate the midpalatal suture (MPS) maturation stages using the cone-beam computed tomography classification method in Chinese children aged 5-10 years, adolescents aged 11-15 years, and postadolescents aged 16-20 years and identify a correlation between maturation stage and age and sex.

Methods: Axial sections of tomographic images from 717 participants (369 female and 348 male participants) aged 5-20 years were used to classify the maturation stage of the MPS (stages A, B, C, D, and E). Kappa statistics were used to evaluate the measurement error. The chi-square test was applied to analyze the differences in the distribution of MPS stages by age group and by sex among all participants, as well as the adolescent group. The Fisher exact test was employed to assess the differences in MPS stage distribution by sex among children aged 5-10 years and among the postadolescent group. The Mann-Whitney U test was used to assess the potential variance in age distribution between stages C and D.

Results: The most prevalent maturation stage was stage C (40.3%). Of the total population, 69.4% had MPS in stages A, B, or C. A significant difference in age distribution was observed between stage C and stage D (P <0.001). The distribution of the MPS maturation stage significantly varied by age group (P <0.001) and sex (P <0.001).

Conclusions: The distribution of participants in advanced maturation stages increases with age. Female patients generally experience earlier MPS maturation than male patients, particularly between the ages of 11-20 years.

使用锥束计算机断层扫描评估 5 至 20 岁儿童的腭中缝成熟阶段。

介绍：本研究旨在采用锥束计算机断层扫描分类法评估中国 5-10 岁儿童、11-15 岁青少年和 16-20 岁后青少年的腭中缝（MPS）成熟阶段，并确定成熟阶段与年龄和性别之间的相关性：方法：采用717名5-20岁参与者（369名女性和348名男性）的断层图像轴切片对MPS的成熟阶段（A、B、C、D和E期）进行分类。卡帕统计法用于评估测量误差。采用卡方检验分析所有参与者以及青少年组中各年龄组和性别的 MPS 阶段分布差异。费雪精确检验用于评估 5-10 岁儿童和青春期后组别中按性别划分的 MPS 分期分布差异。曼-惠特尼 U 检验用于评估 C 阶段和 D 阶段之间年龄分布的潜在差异：结果：最普遍的成熟阶段是 C 阶段（40.3%）。C 期和 D 期之间的年龄分布存在显著差异（P 结论：C 期和 D 期之间的年龄分布存在显著差异：成熟晚期患者的年龄分布随着年龄的增长而增加。女性患者的 MPS 成熟期一般早于男性患者，尤其是在 11-20 岁之间。

期刊介绍： Published for more than 100 years, the American Journal of Orthodontics and Dentofacial Orthopedics remains the leading orthodontic resource. It is the official publication of the American Association of Orthodontists, its constituent societies, the American Board of Orthodontics, and the College of Diplomates of the American Board of Orthodontics. Each month its readers have access to original peer-reviewed articles that examine all phases of orthodontic treatment. Illustrated throughout, the publication includes tables, color photographs, and statistical data. Coverage includes successful diagnostic procedures, imaging techniques, bracket and archwire materials, extraction and impaction concerns, orthognathic surgery, TMJ disorders, removable appliances, and adult therapy.
