咀嚼器官如舌、唇、颊和下颌骨的运动功能已知随着年龄的增长而退化，从而影响咀嚼性能。然而，关于舌、唇功能与咀嚼功能关系的研究报道较少。目的：通过对有牙颌青年人的咀嚼能力、咀嚼混合能力和咀嚼剪切能力的评价，探讨舌唇功能与咀嚼综合能力的关系。参与者包括51名平均年龄为25岁的有齿成年人。测量最大舌压和口腔运动，以评估舌和唇功能。使用花生进行多次筛分方法以评价粉碎能力。进行变色口香糖以评价混合能力。进行测试胶状果冻以评估剪切能力。用Pearson相关系数分析舌唇功能与咀嚼功能的关系。此外，进行逐步多元回归分析，以确定破碎能力的预测因子。压碎能力与最大舌压和音节/pa/、/ta/和/ka/的重复次数显著相关。最大舌压和音节/pa/的重复次数被确定为压碎能力的重要预测因素。混合能力与音节/pa/的重复次数显著相关。剪切能力与舌和唇功能无显著相关性。咀嚼脆性食物（如花生）和固体食物（如口香糖）时的咀嚼表现似乎与舌头和嘴唇的功能相关。
Motor functions of masticatory organs such as the tongue, lips, cheeks and mandible are known to deteriorate with age, thereby influencing masticatory performance. However, there are few reports on the relationships between tongue and lip functions and masticatory performance. To investigate the relationship between tongue and lip functions and comprehensive masticatory performance, by evaluating crushing, mixing and shearing abilities in young dentate adults. Participants comprised 51 dentate adults with a mean age of 25years. Maximum tongue pressure and oral diadochokinesis were measured to evaluate tongue and lip functions. A multiple sieving method using peanuts was performed to evaluate crushing ability. A colour-changeable chewing gum was performed to evaluate mixing ability. A test gummy jelly was performed to evaluate shearing ability. The relationship between tongue and lip functions and each masticatory performance was assessed using Pearson's correlation coefficients. In addition, stepwise multiple regression analysis was performed to identify predictors of crushing ability. Crushing ability was significantly correlated with maximum tongue pressure and the number of repetitions of the syllables /pa/, /ta/ and /ka/. Maximum tongue pressure and number of repetitions of the syllable /pa/ were identified as significant predictors for crushing ability. Mixing ability was significantly correlated with the number of repetitions of the syllable /pa/. Shearing ability was not significantly correlated with tongue and lip functions. Masticatory performance during the chewing of brittle foods such as peanuts and solid foods such as chewing gum appears to be correlated with tongue and lip functions.
