Maintaining good masticatory function from a young age promotes lifelong health, yet limited studies have explored masticatory performance in young individuals. We investigated the relationship of sex, age, and individual oral functions with masticatory performance among junior and senior high school students and young adults.
This cross-sectional study included students aged 12-13, 14-15, and 16-17 years (groups S1, S2, and S3, respectively) and young adults aged 20-40 years (group YA). We assessed oral functions, the number of functional teeth, and anthropometric measurements. Masticatory performance was evaluated using color-changeable chewing gum. We analyzed sex-related differences in each group and age-related differences in each sex. Multiple linear regression analysis was performed using masticatory performance as the dependent variable to investigate related factors.
Among the 522 children and 100 young adults, males exhibited significantly higher masticatory performance than females in groups S1, S3, and YA. Among males, groups S2, S3, and YA exhibited significantly higher masticatory performance than group S1. Among females, group S2 exhibited higher masticatory performance than groups S1 and S3. Male sex, the maximum occlusal force and tongue pressure, and the number of functional teeth were significantly correlated with masticatory performance.
Masticatory function development differed by sex, with males exhibiting higher masticatory performance than females. We identified that male sex, the maximum occlusal force and tongue pressure, and the number of functional teeth were significantly associated with masticatory performance. Our findings provide a basis for masticatory performance assessment in different age groups.
从年轻时就保持良好的咀嚼功能可促进终生健康,但目前很少有研究探讨年轻人的咀嚼功能。我们调查了性别、年龄和个体口腔功能与初中生、高中生和年轻成年人咀嚼功能的关系。
本横断面研究纳入了 12-13 岁(S1 组)、14-15 岁(S2 组)和 16-17 岁(S3 组)的学生和 20-40 岁的年轻人(YA 组)。我们评估了口腔功能、功能牙数和人体测量指标。咀嚼功能采用变色口香糖进行评估。我们分析了每个组中性别差异以及每个性别中年龄差异。采用多元线性回归分析咀嚼功能作为因变量,以探讨相关因素。
在 522 名儿童和 100 名年轻人中,男性在 S1、S3 和 YA 组中的咀嚼功能显著高于女性。在男性中,S2、S3 和 YA 组的咀嚼功能明显高于 S1 组。在女性中,S2 组的咀嚼功能明显高于 S1 组和 S3 组。男性、最大牙合力、舌压和功能牙数与咀嚼功能显著相关。
咀嚼功能的发展因性别而异,男性的咀嚼功能高于女性。我们发现,男性、最大牙合力、舌压和功能牙数与咀嚼功能显著相关。本研究结果为不同年龄组咀嚼功能评估提供了依据。
