Quantitative clinical assessment tests for oral function have become popular in patient assessment; however, their comparability remains unclear.
To assess the reliability and comparability of pairs of different instruments for measuring maximum tongue pressure (MTP), chewing function (CF) and maximum lip force (MLF), and to analyse the influence of subjects' characteristics on the applied instruments.
Each pair of instruments, as well as a single device measuring the maximum voluntary bite force (MBF), was assessed across 26 healthy volunteers. The respective pairs of devices were compared using Bland-Altman plots and linear regression analysis. Furthermore, the influence of age, occlusal support zones, number of functional occlusal units, MBF, MTP and MLF were investigated as predictors on CF using a generalised estimating equation model.
Neither the two assessments of CF, nor of MLF were correlated to each other, but there was a significant correlation between the assessments of MTP. Hue-Check Gum was able to demonstrate a significantly higher CF in younger compared to older individuals (P = .004) and individuals with high numbers compared to low numbers of occlusal units (P < .001). Those differences could not be demonstrated with the Vivident chewing gum.
The absolute values of MTP assessed by the two applied devices cannot directly be compared, although normalised values may be directly comparable. Moreover, our observations suggest that the Hue-Check Gum was able to discriminate the effects of age and the number of occlusal units on CF. Our observations suggest that the two gums cannot be used interchangeably.
用于口腔功能的定量临床评估测试在患者评估中变得越来越流行；然而，它们的可比性仍不清楚。
评估用于测量最大舌压（MTP）、咀嚼功能（CF）和最大唇力（MLF）的不同仪器对的可靠性和可比性，并分析受试者特征对应用仪器的影响。
对 26 名健康志愿者使用每对仪器以及一种单独测量最大随意咬合力（MBF）的设备进行评估。使用 Bland-Altman 图和线性回归分析比较相应的仪器对。此外，使用广义估计方程模型调查年龄、咬合支持区域、功能咬合单位数、MBF、MTP 和 MLF 作为 CF 的预测因子的影响。
CF 和 MLF 的两项评估均彼此不相关，但 MTP 的评估之间存在显著相关性。Hue-Check 口香糖在年轻个体（P =.004）和具有高数量的咬合单位的个体（P <.001）中与年长个体相比，显示出更高的 CF。Vivident 口香糖无法显示出这种差异。
虽然归一化值可能直接可比，但两种应用设备评估的 MTP 的绝对值不能直接比较。此外，我们的观察结果表明，Hue-Check 口香糖能够区分年龄和咬合单位数量对 CF 的影响。我们的观察结果表明，这两种口香糖不能互换使用。
