目的探讨习惯食用硬质口香糖对口腔功能的影响。目的探讨习惯食用硬质口香糖对口腔功能的训练效果。方法将受试者分为训练组(6名女性，8名男性，平均年龄27.6+/-3.5岁)和对照组(2名女性，7名男性，平均年龄28.3±4.9岁)。训练组在为期3个月的时间里，每周三次吃九种定制的硬软糖。通过测量训练前、训练后1、2、3个月、停止训练后1个月、2个月、3个月的最大咬合力、咀嚼能力、最大舌压、吞糖前的咀嚼循环次数、咀嚼持续时间和循环时间来评价训练效果。结果1个月后的咀嚼能力(p=0.01)、2个月后的最大咬合力(p<；0.01)和3个月后的最大舌压(p=0.02)较干预前显著增加(p=0.02)，训练2个月后的周期时间(p=0.02)明显缩短。训练结束后，除咀嚼功能外，其余效果均维持1个月。训练组IEMG/FORCE变化不明显，但有肌肉肥大的趋势。结论习惯性进食硬糖是一种任务专业性训练，能改善包括舌压在内的整体咀嚼功能。
Background Although various training methods have been reported for improving oral function such as occlusal force, there are few reports that show the training effect of eating hard food on the oral functions.Objective To examine the training effects of habitually ating hard gummy candies on oral functions.Methods Participants of this cohort study were recruited into a training (six women, eight men; mean age 27.6 +/- 3.5 years) and control group (two women, seven men; mean age 28.3 +/- 4.9 years). The training group ate nine custom-developed hard gummy candies three times per week for 3 months. Training effects were evaluated by measuring the maximal occlusal force, masticatory performance, maximal tongue pressure, number of chewing cycles until swallowing the candy, duration of chewing and cycle time before training, after 1, 2 and 3 months of training, and 1 month after stopping training. The iEMG/force, which evaluates masseter muscle hypertrophy with electromyograms (EMG), was calculated.Results Masticatory performance after 1 month (p = 0.01), maximal occlusal force after 2 months (p < 0.01) and maximal tongue pressure after 3 months of training were significantly increased (p = 0.02), and the cycle time after 2 months of training (p = 0.02) was significantly decreased compared to before the intervention. Except for masticatory performance, the other effects were maintained for 1 month after stopping training. Changes in iEMG/force were not significant, but a tendency for muscle hypertrophy was observed in the training group.Conclusion Habitual eating of hard gummy candies is a task-specific training that can improve overall masticatory function, including tongue pressure.
