Masticatory function is thought to be related to various eating habits, but it is difficult to evaluate overall masticatory function by assessing complex eating habits. Maximum occlusal force is an important indicator of masticatory function that is affected by age and sex. This preliminary study focused on the maximum occlusal force of young women and their eating habits, excluding food and nutritional factors, and investigated whether individual eating habits and eating habit patterns predict maximum occlusal force. We measured the maximum occlusal force for the whole dentition of 53 healthy young women before they ate lunch. The participants also completed a 12-item questionnaire about their eating habits. Scores were determined from the relationship between each item and increased maximum occlusal force. We found a significant but weak relationship between maximum occlusal force and some questions. The total questionnaire scores for the participants' eating habits showed an almost normal distribution (mean ± standard deviation: 22.7 ± 2.6, median: 23.0, mode: 23.0, range of total scores: 17-28). The accuracy of the linear regression between the total scores for eating habits and maximum occlusal force was high but not perfect (β: standardized regression coefficient = 0.527, P < 0.001). Although further research is needed, our findings confirm that eating habit patterns are significantly associated with maximum occlusal force and may help predict occlusal force. Our results provide important information about eating patterns in humans.
咀嚼功能被认为与各种饮食习惯有关，但评估复杂的饮食习惯很难全面评估咀嚼功能。最大牙合力是咀嚼功能的一个重要指标，它受年龄和性别影响。本初步研究集中于年轻女性的最大牙合力及其饮食习惯，不包括食物和营养因素，并调查个体饮食习惯和饮食习惯模式是否可以预测最大牙合力。我们在 53 名健康年轻女性吃午饭前测量了全牙列的最大牙合力。参与者还完成了一份关于他们饮食习惯的 12 项问题的问卷。通过每个项目与最大牙合力的增加之间的关系确定分数。我们发现最大牙合力与一些问题之间存在显著但较弱的关系。参与者饮食习惯问卷总分呈近似正态分布（均值 ± 标准差：22.7 ± 2.6，中位数：23.0，众数：23.0，总分范围：17-28）。饮食习惯总分与最大牙合力之间的线性回归的准确性较高但并不完美（β：标准化回归系数=0.527，P<0.001）。尽管需要进一步研究，但我们的发现证实饮食习惯模式与最大牙合力显著相关，并可能有助于预测牙合力。我们的研究结果提供了有关人类饮食习惯的重要信息。
