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.
